Installation Instructions

Disconnect the negative cable from the car battery. Tape up the end

so it is isolated form the battery.

Run the power wire from the battery to the amplifier. Plan this part of the

installation carefully. This cable will carry very high current. If it should

short to the body and it is not properly fused it could catch fire.

Connect the power wire to the battery using a fuse capable of the total

current load of all amplifiers connected. Don't install the fuse yet. Wait

until the end. Locate the fuse as close as possible to the battery. If the

fuse is further that 18 inches (wire length) from the battery you should

reevaluate the wire and fuse placement.

Find the closest clear metal area to the amp for a ground. Sand, grind or

scrape all paint and undercoating from the body and screw the ground

securely to the body.

It is advisable to test the ground with an ohmmeter between the

ground cable and the negative battery cable to insure a good low

resistance connection. Some alloys used in modern cars do not

offer the best ground. If you believe this is the case consult with the

vehicle manufacturer.

Run the speaker wire to the speakers. It is advised that you leave some

extra wire at this point. You can "clean it up" later.

If you haven't already done so, mount the amp now.

Connect the power and ground to the amplifier.

Only after this step should you install the fuse at the battery.

Connect the remote wire from the head unit to the amplifier. Now is a

good time to turn on the amp for the first time. Make sure it turns on

properly and does not go into protect.

Connect the speaker wire to the amp and speakers (make sure

the amp is off first). Make sure the polarity (+ and-) is correct.

10.

Connect the RCA's to the amp.

11.

Double check the amplifier controls at this time. Make sure

everything is set correctly for your system.

12.

Now you're ready to play it for the first time. It is best to leave the

gain all the way down at first. Start with the head unit volume low

and work your way up.

13.

Now you can tune the amp. Take your time and make only one

adjustment at a time. It may take some time to get the system

fully adjusted. During this time the amp is drawing current from

the battery. You should check the battery voltage from time to time

and re-charge it if it gets low. Battery voltage can affect the way

the amplifier performs.

14.

You're done. Now have fun.

This amplifier is equipped with an advanced diagnostic system

controlled by the microprocessor. In the event that this unit goes

into protection for any reason it will flash the status light found on

the control end of the amplifier. The different sequences indicate

the "Code" for faster trouble shooting.

GREEN FLASHING

NORMAL TURN ON

THERMAL PROTECTION (Turn the volume

down and wait for the amplifier to cool)

SHORT

(Turn the amplifier off and check

for a shorted speaker or wire.)

REPEATED SHORT

(Correct the short

and leave the amp off for 5 minutes.)

OVERVOLT

(This is a charging system

failure. DO NOT START THE ENGINE.)
