Congratulations on your purchase of a

Sound Storm Laboratories

FORCE Amplifier.

It has been designed, engineered and manufactured to bring you the highest level of performance and quality, and will afford you years of listening pleasure.

Thank you for making Sound

Storm Laboratories your choice for car audio entertainment!

Features About 2 Ohm operation

Your FORCE amplifier has been designed to operate efficiently at loads down to 2 Ohms. This means that you can install four 8 Ohm speakers per channel, when using parallel wiring.

Increasing the number of woofers per channel at low frequencies (below

100Hz) produces an acoustic coupling effect. This acoustic coupling effect increases your power output by about

3dB per speaker, or the equivalent of an additional 10W per speaker.

When operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%. The

current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2Ohm load.

If you lack adequate current, your music reproduction will be distorted.

Introduction

With the Sound Storm Laboratories

FORCE MOSFET amplifier series, we are introducing eleven new amplifiers, all designed in the USA. This new series includes six 2-channel, four

4-channel amplifier and a two monoblock amplifiers.

All FORCE models feature variable low pass crossovers and variable input gain controls. They also incorporate a fixed high pass crossover for added system flexibility, and the F1200M and

F2000M feature an input voltage sensitivity selector.

For further flexibility in the use of a subwoofer, Bass Boost control has been included on all amplifiers: variable 0-+18dB on the two and fourchannel amplifiers, and selectable

0/+18dB on the F1200M and F2000M.

You can control the subwoofer level with the remote level control module.

Sound Storm Laboratories understands that amplifiers are placed in many different kinds of installations, so we have also included an input sensitivity control to help you integrate the amp into your system regardless of the nature of your input source.

What is included?

When first unpacking your new amplifier, please check first that the package contains all of the items below. If something is missing, contact the store where you purchased the player.

• FORCE amplifier

• Remote subwoofer level control

• Remote subwoofer control cable

•High input cable with connector

• Four (4) mounting screws

Features About 2 Ohm operation

Your FORCE amplifier has been designed to operate efficiently at loads down to 2 Ohms. This means that you can install four 8 Ohm speakers per channel, when using parallel wiring.

Increasing the number of woofers per channel at low frequencies (below

When operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%. The

current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2Ohm load.

If you lack adequate current, your music reproduction will be distorted.

Features About 2 Ohm operation

Your FORCE amplifier has been designed to operate efficiently at loads down to 2 Ohms. This means that you can install four 8 Ohm speakers per channel, when using parallel wiring.

Increasing the number of woofers per channel at low frequencies (below

100Hz) produces an acoustic coupling effect. This acoustic coupling effect increases your power output by about

3dB per speaker, or the equivalent of an additional 10W per speaker.

When operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%. The

current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2Ohm load.

If you lack adequate current, your music reproduction will be distorted.

FORCE MOSFET Amplifier User’s Manual - page 3

Before installing and using your new Sound Storm Laboratories amplifier, please become familiar with all the information contained in this manual.

Please keep this manual in a safe place for future reference.

• Do not open or attempt to repair this unit yourself. Dangerous high voltages are present which may result in electric shock. Refer any repairs to a qualified service technician.

• To avoid risk of electronic shock or damage to the amplifier, do not permit any of this equipment to become damp or wet from water or drinks. If this does occur, immediately unplug the power wires and send the amplifier to your local dealer or service center as soon as possible.

• If there is smoke or any peculiar odor present during use or if there is damage to any of the component enclosures, immediately unplug the power wire and send the amplifier to your local dealer or service center as soon as possible .

Installation precautions

Before you drill or cut any holes, investigate your car's layout very carefully. Take special care when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring.

Never operate the amplifier when it is unmounted. Attach all audio system components securely to prevent damage, especially in an accident.

Before making or breaking power connections in your system, disconnect the vehicle battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals.

If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the amplifier. Using a fuse of a different type or rating may result in damage to your audio system or your amplifier which is not covered by the manufacturer's warranty.

Mounting the amplifier

1. Find a suitable location in the vehicle in which to mount the amplifier.

2. Make sure there is sufficient air circulation around the intended mounting location.

3. Mark the location for the mounting hole screws by positioning the amplifier where you wish to install it. Use a scribe or mounting screw, inserted through each of the amp's mounting holes, to mark the mounting surface.

If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen.

4. Drill pilot holes in the mounting surface for the mounting screws. Place the amplifier in position, and attach the amplifier to the mounting surface securely using screws.

SHOCK HAZARD! Do not open the case

of this product. There are dangerous voltages present within the unit. There are no user-serviceable parts within the unit.

7. Insert fuse(s) into the battery fuse holder(s).

8. Recheck all connections before powering up the amplifier.

9. Set all level controls to minimum position, and set all crossover controls/switches to the desired frequency points.

10. Power up the head unit and the amplifier. Then set the volume control on the head unit to about 3/4 volume, and adjust the amplifier’s input level control(s) to just below the level of distortion.

11. Further fine tuning of the various controls may be necessary to obtain best results.

Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for best audio performance.

Troubleshooting

If you experience operation or performance problems with this product, compare your installation with the electrical wiring diagram on the previous pages. If problems persist, read the following troubleshooting tips which may help eliminate the problems.

SYMPTOM POSSIBLE REMEDY

Protection LED comes on when amplifier is powered up.

Check for short circuits on speaker leads.

Turn down the volume control on the head unit to prevent overdriving.

Remove speaker leads, and reset the amplifier. If the Protection LED still comes on, then the amplifier is faulty and needs servicing.

High hiss in the speakers.

Squealing noise from speakers.

Distorted sound.

Amplifier gets very hot.

Engine noise

(static type)

Engine noise

(alternator

whine)

Disconnect all RCA inputs to the amplifiers. If the hiss disappears, then plug in the component driving the amplifier and unplug its inputs. If the hiss disappears at this point, go on until the faulty/noisy component is found.

It is best to set the amplifier's input level control as low as possible. The best subjective signal-to-noise ratio is achieved in this manner. Try to set the head unit as high as possible (without distortion) and the amp input level as low as possible.

Check for improperly grounded RCA interconnects.

Check that the Input Level Control is set to match the signal level of the head unit. Always try to set the Input Level as low as possible.

Check that all crossover frequencies are properly set.

Check for short circuits on the speaker leads.

Check that the minimum speaker impedance for the amp model is correct.

Check that there is good air circulation around the amp. In some applications, it may be necessary to add and external cooling fan.

This is usually caused by poor quality RCA cables,which can pick up radiated noise. Use only the best quality cables, and route them away from power cables.

Check that speaker leads are not shorted to the vehicle chassis.

Check that the RCA grounds are not shorted to the vehicle chassis.

Check that the head unit is properly grounded.

FORCE MOSFET Amplifier User’s Manual - page 4

Connecting the amplifier

Before doing any wiring, look through this manual and identify the diagrams to follow for power, input and speaker connections for your particular installation. Be sure you understand all the connections before you proceed.

1. Connect the power ground terminal to the closest point on the chassis of the car. Keep this ground wire to less than 39" (100 cm) in length. Use 8 gauge (or heavier) wire.

2. Connect the remote terminal to the remote output of the head unit using

16 gauge (or heavier) wire.

3. Connect an empty fuse holder within

18" (45 cm) of the car battery, and run

8 gauge (or heavier) cable from this fuse to the amplifier location.

4. Check that the fuse holder is empty.

Then connect the fuse holder to the

"BATT+" connection on the amplifier.

5. If multiple amplifiers are being used in your system, either:

• Run a separate pair of cables from the battery and a chassis ground point to each amplifier. Each (+) cable must have its own inline fuse.

-or-

• Run a #4 cable from the fuse holder at the battery to a distribution block at or near the amplifier's location. Then run separate cables from the amplifier to this distribution block and to independent chassis ground points.

6. Connect all line inputs and outputs

(if used) using high-quality cables.

Connect all speakers, following the diagrams in this manual. Be sure to observe proper polarity to avoid audio phase problems.

7. Insert fuse(s) into the battery fuse holder(s).

8. Recheck all connections before powering up the amplifier.

9. Set all level controls to minimum position, and set all crossover controls/switches to the desired frequency points.

10. Power up the head unit and the amplifier. Then set the volume control on the head unit to about 3/4 volume, and adjust the amplifier’s input level control(s) to just below the level of distortion.

11. Further fine tuning of the various controls may be necessary to obtain best results.

Don't misuse the level control!

Do not mistake the input level control for a volume control! It is designed

ONLY to match the output level of your audio source to the input level of your amplifier.

Do not adjust this input level to maximum unless your input level requires it.

Ignoring these instructions will result in an input overload to the amplifier, and excessive audio distortion. It can also cause the protection circuit to engage.

Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for best audio performance.

Features About 2 Ohm operation

Your FORCE amplifier has been designed to operate efficiently at loads down to 2 Ohms. This means that you can install four 8 Ohm speakers per channel, when using parallel wiring.

Increasing the number of woofers per channel at low frequencies (below

100Hz) produces an acoustic coupling effect. This acoustic coupling effect increases your power output by about

3dB per speaker, or the equivalent of an additional 10W per speaker.

When operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%. The

current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2Ohm load.

If you lack adequate current, your music reproduction will be distorted.

Features About 2 Ohm operation

Your FORCE amplifier has been designed to operate efficiently at loads down to 2 Ohms. This means that you can install four 8 Ohm speakers per channel, when using parallel wiring.

Increasing the number of woofers per channel at low frequencies (below

100Hz) produces an acoustic coupling effect. This acoustic coupling effect increases your power output by about

3dB per speaker, or the equivalent of an additional 10W per speaker.

When operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%. The

current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2Ohm load.

If you lack adequate current, your music reproduction will be distorted.

FORCE MOSFET Amplifier User’s Manual - page 3

General precautions

Before installing and using your new Sound Storm Laboratories amplifier, please become familiar with all the information contained in this manual.

Please keep this manual in a safe place for future reference.

• Do not open or attempt to repair this unit yourself. Dangerous high voltages are present which may result in electric shock. Refer any repairs to a qualified service technician.

• To avoid risk of electronic shock or damage to the amplifier, do not permit any of this equipment to become damp or wet from water or drinks. If this does occur, immediately unplug the power wires and send the amplifier to your local dealer or service center as soon as possible.

• If there is smoke or any peculiar odor present during use or if there is damage to any of the component enclosures, immediately unplug the power wire and send the amplifier to your local dealer or service center as soon as possible .

FORCE MOSFET Amplifier User’s Manual - page 4

7. Insert fuse(s) into the battery fuse holder(s).

8. Recheck all connections before powering up the amplifier.

9. Set all level controls to minimum position, and set all crossover controls/switches to the desired frequency points.

10. Power up the head unit and the amplifier. Then set the volume control on the head unit to about 3/4 volume, and adjust the amplifier’s input level control(s) to just below the level of distortion.

11. Further fine tuning of the various controls may be necessary to obtain best results.

Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for best audio performance.

Troubleshooting

If you experience operation or performance problems with this product, compare your installation with the electrical wiring diagram on the previous pages. If problems persist, read the following troubleshooting tips which may help eliminate the problems.

SYMPTOM POSSIBLE REMEDY

Protection LED comes on when amplifier is powered up.

Check for short circuits on speaker leads.

Turn down the volume control on the head unit to prevent overdriving.

Remove speaker leads, and reset the amplifier. If the Protection LED still comes on, then the amplifier is faulty and needs servicing.

High hiss in the speakers.

Squealing noise from speakers.

Distorted sound.

Amplifier gets very hot.

Engine noise

(static type)

Engine noise

(alternator

whine)

Disconnect all RCA inputs to the amplifiers. If the hiss disappears, then plug in the component driving the amplifier and unplug its inputs. If the hiss disappears at this point, go on until the faulty/noisy component is found.

It is best to set the amplifier's input level control as low as possible. The best subjective signal-to-noise ratio is achieved in this manner. Try to set the head unit as high as possible (without distortion) and the amp input level as low as possible.

Check for improperly grounded RCA interconnects.

Check that the Input Level Control is set to match the signal level of the head unit. Always try to set the Input Level as low as possible.

Check that all crossover frequencies are properly set.

Check for short circuits on the speaker leads.

Check that the minimum speaker impedance for the amp model is correct.

Check that there is good air circulation around the amp. In some applications, it may be necessary to add and external cooling fan.

This is usually caused by poor quality RCA cables,which can pick up radiated noise. Use only the best quality cables, and route them away from power cables.

Check that speaker leads are not shorted to the vehicle chassis.

Check that the RCA grounds are not shorted to the vehicle chassis.

Check that the head unit is properly grounded.

Features About 2 Ohm operation

Your FORCE amplifier has been designed to operate efficiently at loads down to 2 Ohms. This means that you can install four 8 Ohm speakers per channel, when using parallel wiring.

Increasing the number of woofers per channel at low frequencies (below

100Hz) produces an acoustic coupling effect. This acoustic coupling effect increases your power output by about

3dB per speaker, or the equivalent of an additional 10W per speaker.

When operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%. The

current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2Ohm load.

If you lack adequate current, your music reproduction will be distorted.

FORCE MOSFET Amplifier User’s Manual - page 3

General precautions

Before installing and using your new Sound Storm Laboratories amplifier, please become familiar with all the information contained in this manual.

Please keep this manual in a safe place for future reference.

• Do not open or attempt to repair this unit yourself. Dangerous high voltages are present which may result in electric shock. Refer any repairs to a qualified service technician.

• To avoid risk of electronic shock or damage to the amplifier, do not permit any of this equipment to become damp or wet from water or drinks. If this does occur, immediately unplug the power wires and send the amplifier to your local dealer or service center as soon as possible.

• If there is smoke or any peculiar odor present during use or if there is damage to any of the component enclosures, immediately unplug the power wire and send the amplifier to your local dealer or service center as soon as possible .

Features About 2 Ohm operation

Your FORCE amplifier has been designed to operate efficiently at loads down to 2 Ohms. This means that you can install four 8 Ohm speakers per channel, when using parallel wiring.

Increasing the number of woofers per channel at low frequencies (below

100Hz) produces an acoustic coupling effect. This acoustic coupling effect increases your power output by about

3dB per speaker, or the equivalent of an additional 10W per speaker.

When operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%. The

current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2Ohm load.

If you lack adequate current, your music reproduction will be distorted.

FORCE MOSFET Amplifier User’s Manual - page 3

General precautions

Before installing and using your new Sound Storm Laboratories amplifier, please become familiar with all the information contained in this manual.

Please keep this manual in a safe place for future reference.

• Do not open or attempt to repair this unit yourself. Dangerous high voltages are present which may result in electric shock. Refer any repairs to a qualified service technician.

• To avoid risk of electronic shock or damage to the amplifier, do not permit any of this equipment to become damp or wet from water or drinks. If this does occur, immediately unplug the power wires and send the amplifier to your local dealer or service center as soon as possible.

• If there is smoke or any peculiar odor present during use or if there is damage to any of the component enclosures, immediately unplug the power wire and send the amplifier to your local dealer or service center as soon as possible .

FORCE MOSFET Amplifier User’s Manual - page 4

7. Insert fuse(s) into the battery fuse holder(s).

8. Recheck all connections before powering up the amplifier.

9. Set all level controls to minimum position, and set all crossover controls/switches to the desired frequency points.

10. Power up the head unit and the amplifier. Then set the volume control on the head unit to about 3/4 volume, and adjust the amplifier’s input level control(s) to just below the level of distortion.

11. Further fine tuning of the various controls may be necessary to obtain best results.

Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for best audio performance.

Troubleshooting

If you experience operation or performance problems with this product, compare your installation with the electrical wiring diagram on the previous pages. If problems persist, read the following troubleshooting tips which may help eliminate the problems.

SYMPTOM POSSIBLE REMEDY

Protection LED comes on when amplifier is powered up.

Check for short circuits on speaker leads.

Turn down the volume control on the head unit to prevent overdriving.

Remove speaker leads, and reset the amplifier. If the Protection LED still comes on, then the amplifier is faulty and needs servicing.

High hiss in the speakers.

Squealing noise from speakers.

Distorted sound.

Amplifier gets very hot.

Engine noise

(static type)

Engine noise

(alternator

whine)

Disconnect all RCA inputs to the amplifiers. If the hiss disappears, then plug in the component driving the amplifier and unplug its inputs. If the hiss disappears at this point, go on until the faulty/noisy component is found.

It is best to set the amplifier's input level control as low as possible. The best subjective signal-to-noise ratio is achieved in this manner. Try to set the head unit as high as possible (without distortion) and the amp input level as low as possible.

Check for improperly grounded RCA interconnects.

Check that the Input Level Control is set to match the signal level of the head unit. Always try to set the Input Level as low as possible.

Check that all crossover frequencies are properly set.

Check for short circuits on the speaker leads.

Check that the minimum speaker impedance for the amp model is correct.

Check that there is good air circulation around the amp. In some applications, it may be necessary to add and external cooling fan.

This is usually caused by poor quality RCA cables,which can pick up radiated noise. Use only the best quality cables, and route them away from power cables.

Check that speaker leads are not shorted to the vehicle chassis.

Check that the RCA grounds are not shorted to the vehicle chassis.

Check that the head unit is properly grounded.

Troubleshooting

If you experience operation or performance problems with this product, compare your installation with the electrical wiring diagram on the previous pages. If problems persist, read the following troubleshooting tips which may help eliminate the problems.

SYMPTOM POSSIBLE REMEDY

Protection LED comes on when amplifier is powered up.

Check for short circuits on speaker leads.

Turn down the volume control on the head unit to prevent overdriving.

Remove speaker leads, and reset the amplifier. If the Protection LED still comes on, then the amplifier is faulty and needs servicing.

High hiss in the speakers.

Squealing noise from speakers.

Distorted sound.

Amplifier gets very hot.

Engine noise

(static type)

Engine noise

(alternator

whine)

Disconnect all RCA inputs to the amplifiers. If the hiss disappears, then plug in the component driving the amplifier and unplug its inputs. If the hiss disappears at this point, go on until the faulty/noisy component is found.

It is best to set the amplifier's input level control as low as possible. The best subjective signal-to-noise ratio is achieved in this manner. Try to set the head unit as high as possible (without distortion) and the amp input level as low as possible.

Check for improperly grounded RCA interconnects.

Check that the Input Level Control is set to match the signal level of the head unit. Always try to set the Input Level as low as possible.

Check that all crossover frequencies are properly set.

Check for short circuits on the speaker leads.

Check that the minimum speaker impedance for the amp model is correct.

Check that there is good air circulation around the amp. In some applications, it may be necessary to add and external cooling fan.

This is usually caused by poor quality RCA cables,which can pick up radiated noise. Use only the best quality cables, and route them away from power cables.

Check that speaker leads are not shorted to the vehicle chassis.

Check that the RCA grounds are not shorted to the vehicle chassis.

Check that the head unit is properly grounded.
