This amplifier is designed to work within a 9 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. 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. Remember Bigger is Better!
*** WARNING ***
Disconnect the negative (-) battery terminal before you start any wiring work! The bat-
tery of your car audio system must be disconnected until the entire wiring installation is
completed.
Your PowerBass Autosound Mono amp will draw large levels of current, so use the largest gauge power/
ground cable possible. Using too small of power cable can result in unnecessary over-heating of the ampli-
fier, 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 amplifier 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 wir-
ing harnesses, fuel pumps etc.)
