Page 1: Owners Manual
XTA 4000D XTA 5000D XTREME SERIES CLASS D 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. - Page 3 AMPLIFIERS Thank you and Congratulations Thank you for your decision to purchase a PowerBass Xtreme mobile amplifier! Our PowerBass Xtreme am- plifiers are the result of extensive engineering, testing, and bullet proof construction. They feature the latest in D Class microprocessor technology. Their versatility enables compatibility with optional signal and audio processors.
- Page 4 Keys To Safe Installation Since you are reading this, you’re probably reading the manual; hopefully very carefully. We have warnings here for your protection. Please pay close attention to the warnings in this manual. This will help give you years of safe listening enjoyment. The PowerBass XTA5000D can develop over 5000 watts RMS, and can draw well over 400 Amps.

Page 5: Technical Features
Installation of PowerBass mobile amplifiers requires detailed knowledge of electronics wiring and proper speaker impedance. We strongly recommend installation by an authorized PowerBass Xtreme dealer. This Owners 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. -
Page 6: Mounting The Amplifier
MOUNTING LOCATION Your PowerBass Xtreme D Class amplifier comes with mounting feet that may need to be attached to the am- plifier prior to installation. Once the feet are in place, use the amplifier as a template and mark the four screw locations. - Page 7 The amplifier should be protected from exposure to moisture and direct sunlight. 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 dealer. *** WARNING *** •...

LPF (Low Pass Filter) Control This control is continuously adjustable and varies the crossover point from 50Hz to 250Hz at 24dB per oc- tave. - Page 10 14. REM (Remote Input Terminal) All Powerbass Xtreme amplifiers can be turned on by applying 12 volts to this terminal. This can be found a the rear of the source unit (usually the blue with white stripe wire). If there is not a remote turn on lead the power antenna lead (usually blue) can be used in its place.

Page 11: Wiring And Connections
Your PowerBass Xtreme Class D amp will draw large levels of current, so use the largest gauge power/ ground cable possible. 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 may even cause the thermal protection circuitry to shut off the amplifier. - Page 12 This amplifier is designed to work within a 10 to 16.5 volt DC range. Before any wires are connected, the vehicles electrical system should be checked for correct supply voltage with the help of a voltmeter. The gauge of the power and ground cables must be capable of handling the current needed by the entire system.
- Page 13 REM (Remote) 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.

Page 14: Rca Interconnect Wiring
RCA INTERCONNECT WIRING 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. Most trunk/hatchback installations will require a 15-20 foot (4.5 meter) RCA cable, while pickup trucks will require a 6-12 foot (2 meter) RCA cable. -
Page 15: Input Gain Adjustment
Remote Gain Controller Connection Fig.5 Connection with RJ12 Jack Your PowerBass Xtreme D Class amp includes a remote GAIN control module. It uses standard 6-pin telephone wire and modular (U.S.A. style) telephone connectors. To connect the remote GAIN Control to the amplifier, simply insert one end of the telephone plug into the REMOTE GAIN port. -
Page 16: Phase Adjustment
BASS EQ 18dB Fig.7 Bass EQ Control Bass EQ Adjustment This special feature is designed to provide you boost at 45Hz, and it allows you to boost the real Bass EQ up to +18dB. Keep in mind that more is not always better. Setting the control (fig. 7) to the max (18dB) will stress the amplifier and the speakers and could result in damage. -
Page 17: Speaker Wiring
Speaker Load Keep in mind your PowerBass Xtreme D Class amp is a high power amplifier and not a high current amplifier. In other words it requires a minimum impedance of 1 ohm. Both speaker outputs are internally paralleled, thus a minimum speaker impedance of 2 ohms is required when using more then one of the speaker outputs. - Page 18 Too low of an impedance could send your amplifier into protection mode and/or permanently damage the amplifier. At the amplifier end, insert the stripped (bare) speaker wires into the properly marked terminals. Use a Philips (cross) screwdriver to loosen the speaker terminals on the amplifier. Make certain that no bare wire ends touch each other.

If a impedance load of less than the 1-ohm minimum is used, you will eventually damage your amplifier and void your warranty!
- Page 21 Wiring for Dual Link/Strapping Two Amplifiers Connect an RCA cable from the head unit or other signal source to the LINE IN on the MASTER amplifier. Connect single channel RCA cable from the SLAVE OUTPUT RCA jack to the SLAVE IN RCA jack on the SLAVE amplifier as shown below.
- Page 22 You must follow the preceding diagrams carefully when attempting to wire two of the same model PowerBass Xtreme Class D amplifiers together. Make sure the MASTER and SLAVE switches are properly selected on each amplifier as shown (see #6). Failure to do so will result in damage to the system.

Page 23: Reconnect Battery
(or both) speaker wires may be disconnected. Protection Indicator All PowerBass Xtreme amplifiers incorporate self diagnostic Multi-Protection circuitry. This four- way system protects against Impedance Overload, Speaker Short Circuit, Thermal Overheating, and DC Output. The RED L.E.D. provides a visual indication that a problem exists and the protec- tion circuitry has protected the amplifier by shutting down. -
