This amplifier is designed to work within a 9-16 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. We recommend using as large a gauge cable as possible, use the Power Cable Selection
Chart to calculate 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.
Your PowerBass Xtreme Class D amp will draw large levels of current, so use the largest gauge power/ground
cable as possible. Using too small of 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!
•
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 wiring
harnesses, fuel pumps etc.)
