TROUBLESHOOTING

Continued...

AMPLIFIER FUSE KEEPS BLOWING? 1) Incorrect wiring or short circuit: Using your DMM, make sure that all voltage polarities are correct, review section

(Installation) for proper wire connection. 2) Amplifi er being driven too hard: Turn down the volume. Gain or

Bass Boost not properly set, Review section (Tuning) for setting the Gain and Bass Boost properly. 3)

Under-sized or faulty fuse installed: Replace the fuse with a fuse of the same rating in accordance with the manufacturer’s suggestion.

WHINING NOISE WHEN ENGINE IS ON? 1) RCA cables too close to power wire: Separate RCA and power cables, Run an extra set of RCAs on the outside of the vehicle, and if noise is eliminated, you might need a better shielded RCA cable. 2) Ground loop problem: Re-Ground the amplifi er to a more electrically conductive location, Re-Ground the stereo head unit to a more electrically conductive location,

Re-ground the amplifi er to a point of the vehicle that is secure and not thin metal. Make sure that bare metal is in contact with the connector. 3) Induced noise: Relocate components away from electrical noise sources such as engine control computers and

ABS brake control modules.

AMPLIFIER SHUTS DOWN AFTER PLAYING FOR

A PERIOD OF TIME? 1) Thermal protection circuits are shutting the amplifi er off: Check the location for adequate ventilation (Relocate amplifi er if necessary),

Impedance may be too low and overheating the amplifi er.

GETTING STARTED

Mounting

• Mount the amplifi er on a fl at, secure surface.

• Investigate the layout of your automobile thoroughly before drilling.

• Place the amplifi er in a location that allows air to circulate around it to keep it cool.

• If possible, mount the amplifi er vertically for proper heat dissipation.

• Avoid mounting the amplifi er upside-down as this will not provide adequate ventilation for the amplifi er.

• In order to prevent overheating, avoid covering the amplifi er with carpet or enclosing it behind the interior panels.

• If the amplifi er is installed in a tight area, it must have at least a 1-inch air gap all around for proper cooling.

WARNING!

• Be aware of gas tanks, gas lines, hydraulic lines and electrical wiring when drilling mounting holes to prevent serious or life threatening injuries.

• Do not leave the amplifi er unmounted in order to prevent the unit from ejecting like a projectile in the unexpected event of an accident.

• Do not mount the amplifi er on top of wires or metal surfaces in order to prevent electrical short circuit or a fi re.

• Never mount the amplifi er in the engine compartment.

TROUBLESHOOTING

If the bass package system does not appear to be working properly, check the following troubleshooting suggestions.

NO SOUND? 1) Source unit volume is turned down or muted: Turn volume up slowly or turn mute off.

2) Amplifi er may not be receiving an input signal:

Check the output signal of the audio source using an AC voltmeter. 3) Speaker wires are not properly connected to the enclosure terminal: Check speaker connections at amplifi er and at speaker box terminals,

4) Blown fuse on the amplifi er: Replace with new fast-blow fuse (same rating). 5) Power wires are not making proper connections: Check battery terminal connections, Check amplifi er terminal connections,

Use a DMM and check power voltages at all power terminals. 6) Speaker wires shorted: Check all speaker wires and ensure that bare wires are not touching metal or each other.

DISTORTED AUDIO? 1) Gain may not be properly set: Review section (Calibration) for setting the

Gain properly. 2) Speaker wires may be shorting out: Inspect the speaker wires from each terminal connection and along the wire route. Make sure wires are not pinched or exposed. 3) Speaker may be damaged: Inspect each speaker cone for signs of damage (frozen cone, burned smell, separated or ripped surround or spider).

CALIBRATION

Continued...

Setting Bass Boost

1. Turn the gain and bass control all the way down (counterclockwise).

2. Turn the vehicle on, and make sure the source unit is turned on.

3. Insert a CD/DVD with undistorted music.

4. Start to increase the volume at the source unit until you hear distortion (about 90%).

5. Turn the volume down at the source unit until the distortion goes away.

6. At the amplifi er, slowly turn the Bass Boost control up (clockwise) until you hear a slight distortion from the speakers.

7. Turn the Bass Boost control back down until the distortion goes away.

8. When the Bass Boost control is properly set, you should be able to achieve the maximum undistorted output with the volume turned all the way up.

Warning!

Do not set or increase the amplifi er’s gain when setting the Bass Boost control. Increasing the gain even slightly will cause the amplifi er to heat up and amplifi er failure could occur.

17

Wiring

• Before you begin routing and connecting the power wires, disconnect the negative ground cable from the vehicle’s battery.

• Install and connect the highest possible wire gauge the amplifi er’s terminal will accept (1/0

GAUGE) for both power cables (+12V and GND).

• Install an in-line fuse into the positive (+) wire 18 inches away from the car battery. It should be the same rating as the amplifi er’s internal fuse(s)

• Route all power and speaker wires inside the vehicle toward the amplifi er prior to mounting it.

• Avoid routing electrical wires where they are at risk of getting pinched.

• Use rubber or plastic grommets to protect any wires when routing through metal.

• Route the power cables through one side of the vehicle while routing the RCA audio cables through the other side.

• The ground connections should be as short as possible and always be connected to chassis metal. Chassis ground connection should be clean, rust free, unpainted and as close to the amplifi er as possible.

WARNING!

• Disconnect the negative (-) battery terminal before routing cables and wires to prevent electrical shorts.

• Never route wires underneath the vehicle.

• Do not run wires through sharp edges.

• Always turn off amplifi er(s) before making any type of connection.

INSTALLATION

Make sure to mount the amplifi er in a location where there is enough room to have access to the knobs and terminals.

1. Turn the gain and bass control all the way down (counterclockwise).

2. Turn the vehicle on, and make sure the source unit is turned on.

3. Insert a CD/DVD with undistorted music.

4. Start to increase the volume at the source unit until you hear distortion (about 90%).

5. Turn the volume down at the source unit until the distortion goes away.

6. At the amplifi er, slowly turn the Gain control up (clockwise) until you hear a slight audio distortion.

7. Turn the Gain control back down until the audio distortion goes away.

8. When the Gain control is properly set, you should be able to achieve the maximum undistorted output with the volume turned all the way up.

Warning!

Do not set the amplifi er’s gain very high as noise, distortion and amplifi er heat will increase signifi cantly and amplifi er failure could occur.

If Bass Boost is used, keep the Gain setting down.

AUDIO INPUT

The audio inputs on the side panel of the amplifi er receive low level signals from the RCA outputs of the stereo head unit. If your stereo head unit does not have RCA outputs, a High-to-Low level converter (not included) must be used. Both line inputs need to be connected to the stereo head unit in order to use all of the speaker outputs.
