XAX 500D XTREME SERIES MINI AMPLIFIER Owners Manual Please read through this manual to familiarize yourself with your new amplifier. Should your PowerBass Xtreme mobile amplifier ever require service, you will need to have the original dated receipt.

In the interest of safety, PowerBass USA highly recommends listening at lower volume levels when driving.
Wired Remote Gain Control INSTALLATION EXPERIENCE Installation of PowerBass mobile amplifiers requires detailed knowledge of electronics wiring and proper speaker impedance. We strongly recommend installation by an authorized PowerBass dealer. This Own- ers Manual only provides general installation and operation instructions. If you have any reservations about your installation skills, please contact your local PowerBass dealer for assistance.
MOUNTING THE AMPLIFIER Fig.1 Mounting the Amplifier Due to the high power output of the PowerBass Xtreme Class D amplifiers, considerable heat may be produced when the unit is in operation. For this reason the amplifier should be mounted in a location which will allow air to circulate freely.
The amplifier should be protected from exposure to moisture and direct sunlight. 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 the driver’s seat, or on the back of the rear seat. For alternate installation locations, please consult your authorized PowerBass Dealer.
CONTROL PANEL LAYOUT 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 output of 500mV is required for proper operation.

5. BRIDGED CONNECTION Port For linking two of the same model PowerBass Autosound Class D amps together. Connect the INPUT of the MASTER to a suitable source via a standard telephone wire with RJ45 modular connectors to the jack on the SLAVE amplifier.

16. REMOTE (Remote Input Connection) All PowerBass Xtreme amplifiers can be turned on by applying 12 volts to this terminal. This can be found on the rear of the source unit in the form of an electric antenna output, or a remote output. If this is not available you can wire to the ACC position on the key.

Your PowerBass Autosound 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 am- plifier, distortion at high volume levels and might even cause the thermal protection circuitry to shut-off the amplifier.
POWER WIRING BATT+ (Power) This amplifier should be wired directly to the vehicle battery using the appropriate size cable. Start at the vehicle battery and run the power cable through to the amplifier. Avoid running the power cable over engine components and near heater cores.

REMOTE (Remote Trigger) This terminal must be connected to a switched +12V source. Typically, remote turn-on leads are provided at the source unit that will turn on and off the amplifier in correspondence with the source. If the source unit does not have a remote turn-on lead, then a power antenna wire can be used.
RCA INTERCONNECT WIRING 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 four simple steps: Make sure that the remote gain control is not plugged in until after the master gain control is set.

Fig.9 Connection with RJ45 Jack Remote Gain Controller Connection Your PowerBass Xtreme Class D amp includes a Remote Gain control module. It uses standard telephone wire and telephone RJ45 connectors. To connect the Remote Gain Control to the amplifier, simply insert one end of the telephone plug into the REMOTE Gain port.
Speaker Load Keep in mind your PowerBass Autosound Class D amp is a high power amplifier and not a high current ampli- fier. In other words it requires a minimum impedance of 1 ohm. If you are unsure of calculating impedance loads please consult your Authorized PowerBass Autosound Dealer before damaging your amplifier.

Maintaining proper impedance is critical when wiring the Class D model amplifiers. Improper wiring can cause severe damage to BOTH the woofer and the amplifier. Detailed wiring diagrams are supplied with all PowerBass woofers. IF YOU ARE NOT EXPERIENCED OR UNCOMFORTABLE READING THE WIRING DIAGRAMS CONSULT...

NOTE: If the Status L.E.D. is activated and glows RED with no speakers connected to the amplifier, and all the power connections are correct, this would indicate an internal problem with the ampli- fier. Contact PowerBass USA or your local dealer.
