(volume) to maintain operation. For this reason the amplifier should be mounted in a location which will allow air to circulate freely. The compact size of the PowerBass XAX Series amplifier allows greater flexibility in mounting.
The best places to mount your amplifier are: The floor of the trunk, under a seat, or on the back of the rear seat. For alternate installation locations, please consult your authorized PowerBass Dealer. *** WARNING *** •...
CONTROL PANEL LAYOUT BRIGED BA TT+ REMOTE FUSE SPEAKER OUTPUT Fig.2 Panel Layout NOTE: Panel Layout and Controls may differ by model. 1. Line INPUT (RCA) Jacks These RCA style input jacks are for use with source units that have RCA line level outputs. A source unit with a minimum of 0.5 volt is required for proper operation.
12. GND (Ground Input Connection) A good quality ground is required for your PowerBass Xtreme amplifier to operate at peak performance. A short length of cable the same gauge as the Power cable should be used to attach the Ground terminal directly to the chassis of the vehicle.

Remember, bigger wire is better! For best results we recommend a PowerBass ampli- fier install kit, available at your local PowerBass dealer.
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.

Secure the ground cable to the body using a bolt, star washer and nut. Spread silicon over the screw and bare metal to prevent rust and possible water leaks. NOTE: The Ground must be capable of carrying the same amount of current as the positive wire. Now it’s time to connect the power and ground cables to the amplifier.

RCA INTERCONNECT Fig.4 Low Level Input using RCA Choose the correct length and style of RCA interconnects for your needs. Always use high quality RCA audio cables (not supplied) for signal connections—those with multiple layers of shielding or a twisted pair variety for better noise rejection.
SET UP ADJUSTMENTS INPUT Gain Adjustment GAIN Input Sensitivity Control Fig.5 GAIN Control This control allows you to match the input level of the amplifier to the output level of your head unit. Matching the input can be accomplished in three simple steps: Set the volume of GAIN on the amplifier to Min (completely counter clock wise).
