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 first. Every installation will be
different 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 final.
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 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. You
DID use a grommet when you ran it through the firewall, didn't you?
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 than 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. 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 alloys used in modern cars do not offer 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 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.
Connect the RCA signal wires to the amp.
Double check the amplifier controls at this time. Make sure everything is set correctly for your system.
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.
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.
