CAR AUDIO POWER AMPLIFIER OWNER’S MANUAL

Installation Warnings and Tips:

• Always wear protective eyewear when using tools.

• Disconnect the negative (–) lead from your vehicle’s battery.

• At the installation sites, locate and make a note of all fuel lines, hydraulic brake lines, vacuum lines and electrical wiring. Use extreme caution when cutting or drilling in and around these areas.

• If the amplifier’s fuse must be replaced, use only the same type and rating as that of the original.

• Choose a mounting location in the trunk or cargo area where the amplifier will not be damaged by shifting cargo.

• Make sure there is sufficient air circulation at the mounting location for the amplifier to cool itself.

• Make sure that the amplifier is mounted securely using nuts and bolts or the supplied mounting screws.

• Mount the amplifier so that it remains dry – never mount an amplifier outside the vehicle.

What’s in the Box?

(4) #8 x 2-1/2" Philips panhead screws for mounting the amplifier

(2) 20A ATC-type fuses

0 Speaker Output Connectors

• Connect the speakers to these terminals observing proper polarity.

• Four-channel operation: Connect the front left speaker to the Front L+ and L– terminals, and the front right speaker to the Front R+ and R– terminals. Repeat for rear speakers using the

Rear R+ and R– terminals.

• Three-channel operation: Connect the stereo speakers to the Front terminals as above.

Connect the single speaker into which the amplifier’s rear channels will be bridged to the

Rear R+ and Rear L– terminals.

• Two-channel (bridged) operation: Connect one speaker to the Front R+ and Front L– terminals. Connect the other speaker to the Rear

R+ and Rear L– terminals.

• Minimum speaker impedance for stereo operation is 2 ohms. Minimum speaker impedance for bridged operation is 4 ohms.

1 Fuses

• Replace only with same type and rating.

2 Power Input Connectors

• +12V: Connect to the positive terminal of the vehicle’s battery. 8 AWG wire is recommended.

Install an appropriate fuse holder and fuse (40A minimum) within 18 inches of the battery. Make sure the wire is not damaged or pinched during installation. Install protective grommets when routing wires through the firewall or other sheet metal.

• GND: Connect to the vehicle’s chassis. Clear away the paint from the chassis location where you will connect the ground wire. Use a ring terminal, tapping screw and star washer.

Factory Bolt Ring Connector

Note: Remove any paint below ring connector.

Ground Wire

Star Washer

• REM: Connect to the “Remote Out” lead from source unit or to a source of switched 12V+

(ACC).

3 Aux Output Connectors (RCA)

• Summed, nonfiltered pass-through output.

Front right and rear right inputs are combined and sent to the right AUX output. Front left and rear left inputs are combined and sent to the left AUX output. Connect to the input of an additional subwoofer amplifier.

4 Front Input Connectors (RCA)

• Connect to front RCA outputs from the source unit or signal processor.

5 Front Input-Level Control

• Used to match the front input level of the amplifier to the output level of the source unit.

• See F for adjustment procedure.

6 Front Crossover-Frequency Control

• 12dB/Octave crossover, variable from

32Hz to 320Hz.

• See G for adjustment procedure.

7 Front Crossover-Filter Selector

• LPF – Select for subwoofer(s).

• Flat – Select for full-range speakers when no subwoofer will be used in the system.

• HPF – Select for midrange speakers or full-range speakers when a subwoofer is used in the system.

8 Rear Bass-Boost Control

• Set the Bass-Boost control according to your preference, being careful not to apply enough boost to damage your speaker(s).

9 Rear Crossover-Filter Selector

• LPF – Select for subwoofer(s).

• Flat – Select for full-range speakers when no subwoofer will be used in the system.

• HPF – Select for midrange speakers or full-range speakers when a subwoofer is used in the system.

A Rear Crossover-Frequency Control

• 12dB/Octave crossover, variable from

32Hz to 320Hz

• See adjustment procedure in G.

B Rear Input-Level Control

• Used to match the rear input level of the amplifier to the output level of the source unit.

• See 16 for adjustment procedure.

C Power On LED

• Illuminated when the amplifier is on.

D Protect LED

• Illuminated under any of the following fault conditions: Battery over/under voltage, short circuit in speaker wires, amplifier is too hot, amplifier’s output circuit has failed (DC voltage present in the amplifier’s output).

E Rear Input Connectors (RCA)

• Connect to rear RCA outputs from the source unit or signal processor.

F Setting Input Level

A Turn all Input-Level controls counterclockwise to 6V (minimum).

B With a dynamic music track playing, turn head unit’s volume control to the 3/4 position.

C Turn Front Input-Level control clockwise until the music is so loud that it no longer sounds clear (distortion is present in the output).

D Turn Front-Input-Level control counterclockwise gradually, just until the music sounds clear, once again.

E Front-level input is now adjusted correctly.

F Adjust Rear Input-Level control so that the level of the rear speakers is proportionate to the level of the front speakers according to your preference.

G Setting the Crossover

A Crossover setting for 5" or larger full-range speakers when no subwoofer is included in the system.

B Crossover setting for midrange and/or full-range speakers when a subwoofer is included in the system.

C Crossover setting for subwoofers.

Note: Acceptable frequency ranges indicated in gray.

Amplifier Troubleshooting Guide

1. Status LED on Amplifier not Lit - Head Unit (Source) Turned ON

Verify:

A. Remote turn-on wire from source to amplifier has proper voltage

B. Power (B+) connections at amplifier, terminal blocks, and battery are secure

C. Ground (GND) connections at amplifier and vehicle chassis are secure

D. Battery B+ fuse (if used) is OK

E. Amplifier fuse is OK

F. B+ at battery and B+ at amplifier has proper voltage

2. Status LED’s Lit, No Output from Speakers in Normal Operating Condition

Verify:

A. RCA cables from amplifier to source are securely connected

B. Volume adjustment on amplifier is correctly adjusted

C. Source is ON and playing

3. Engine Noise From Speaker(s)

Turn source OFF, Disconnect RCA cables at amplifier. If noise stops, check equipment & cables leading to amplifier.

Verify:

A. RCA cables are of good quality with no breakage to internal shields

B. RCA cables from source to amplifier are not run alongside any power cables

4. Amplifier Output Distorted Music

Verify:

A. Source output music to amplifier is not distorted

B. Source output sensitivity is correctly adjusted

5. Amplifier Shuts Down, Green LED.s are Lit - Amplifier is in Thermal Protection Mode

Verify:

A. Amplifier is mounted with adequate air circulation around heatsinks or vents

B. Amplifier is not mounted under carpet or sealed enclosure

C. Speakers meet correct impedance for application (mono or stereo hookup)

6. Amplifier Does Not Turn ON, and Red LED is Lit Amplifier (and not Connected to a Shorted Speaker)

Verify:

A. Speaker crossover (if used) is not defective
