Your PowerBass Xtreme amplifier requires unrestricted current to deliver peak performance, so do not “starve”
your amplifier by using small power cable. Using under sized power cable can result in unnecessary over-
heating of the amplifier, distortion at high volume levels and might even cause the thermal protection circuitry
to shut-off the amplifier. Remember, bigger wire is better! For best results we recommend a PowerBass ampli-
fier install kit, available at your local PowerBass dealer.
•
Use rubber grommets when running cables through any metal or sharp plastic, to prevent accidental
shorting or shearing. Make sure the cables do not interfere with normal operation of the vehicle.
•
The audio signal cables (RCA interconnects) should be kept far away from any potential sources of
electrical interference such as electronic vehicle management systems (relays, engine computers etc.),
wiring harnesses, fuel pumps etc.
These amplifiers are designed to work within a 10 to 16 volt DC range. Before any wires are connected, the
vehicles electrical system should be checked for correct voltage supply with the help of a voltmeter.
First, check the voltage at the battery with the ignition in the OFF position. The voltmeter should read no less
than 12V. If your vehicles electrical system is not up to these specifications, we recommend having it checked
by an auto electrician before any further installation. Once the vehicle is checked, make certain the correct
cable gauge is used. The XL amplifier terminals are capable of accepting up to 4 gauge power and ground
cable. We recommend using as large a gauge cable as possible, use the Power Cable Selection Chart to cal-
culate the correct power wire size for your application.

*** WARNING ***
Disconnect the negative (-) battery terminal before you start any wiring work! The
battery of your car audio system must be disconnected until the entire wiring
installation is completed.
