Installation Instructions

Below is a very abbreviated set of installation instructions. This is not meant as a step by step procedure but is

intended to give you a general idea of what is involved and which steps come rst. Every installation will be

di erent and may require reordering of these steps. NEVER install the fuse at the battery or connect the negative

battery cable until all your connections are nal.

Before you start, disconnect the negative cable from any batteries in the car. Tape up the end so it is isolated from

the battery.

Run an appropriate gauge wire from the battery to the ampli er (8 AWG Min.). 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 re. You DID use a grommet or loom when you ran it through any metal bulkheads, didn't you?

Connect the power wire to the battery using a fuse that does not exceed the fuse rating or the ampli er

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 than 18 inches (wire length) from the battery, you should reevaluate the wire and fuse placement.

Find a close clear metal area to the amp for a ground. In many cases the best ground location is the batter itself.

Sand, grind or scrape all paint and undercoating from the body and screw the ground securely in place. A nut, bolt

and lock washer is advisable here.

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 modern alloys do not o er the best ground. If you believe this is

the case, consult with the vehicle's 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 ampli er.

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

Connect the remote wire or select the auto sense feature if compatable. Now is a good time to turn on the amp for

the rst 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 o

rst). Make sure the polarity (+ and -)

is correct.

Connect the RCA signal wires to the amp.

Double check the ampli er controls at this time. Make sure everything is set correctly for your system.

Now you're ready to play it for the rst time. It is best to leave the gain all the way down at rst. Start with the head

unit volume low and work your way up.

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.

ave fun.
