Installation Instructions

Before you start, disconnect the negative cable from the car battery. Tape up

the end so it is isolated form the battery.

Run an appropriate gauge 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 in place.

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 protection.

Connect the speaker wires 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. That's it.

You're done. Now have fun.
