XMA MINI CLASS D MONO AMPLIFIER Owners Manual Please read through this manual to familiarize yourself with your new ampliﬁ er. Should your PowerBass Xtreme mobile ampliﬁ er ever require service, you will need to have the original dated receipt.
Page 2: Technical Features
Fan Cooling (XMA-1205D only) 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 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 3: Installation Precautions
Fan (XMA-1205D only) 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.
Page 4: Mounting Location
For alternate installation locations, please consult your authorized PowerBass Dealer. If mounting under a seat, make sure there is at least 1-inch (2.5cm) of space above the ampliﬁers heatsink to permit proper cooling.

5. BRIDGED CONNECTION Port For externally bridging two of the same model PowerBass Xtreme Class D amps together. Connect the INPUT of the MASTER to a suitable source via a standard telephone wire with RJ11 (4-pin) modular connectors to the jack on the SLAVE ampliﬁer.
Page 8 17. REM (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 a remote output. If this is not available you can wire to the ACC position on the key. An 18 gauge wire is sufﬁcient to run the REMOTE.
Page 9 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.
Page 10: Power Wiring
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.
Page 11: Fuse Requirements
FUSE REQUIREMENTS While the panel on your PowerBass ampliﬁer may use one or more fuses, these do nothing to protect the vehicle from a dangerous short circuit. It is absolutely vital that the main power lead to the ampliﬁer(s) in the system be fused within 18-inches (45cm) of the connection to the vehicle battery.
Page 12 RCA INTERCONNECT WIRING Fig.5 Low Level Input using RCA Low Level Input - 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.
Page 13 The balanced input of this XMA series ampliﬁer can receive either low RCA or high speaker lead level signals from the source unit (radio). A high level signal can be run from the source units speaker lead outputs to the low level RCA ampliﬁer inputs via the PowerBass HL-AD2 wiring harness (available separately as shown below).
Page 14: Set-Up Adjustments
SET UP ADJUSTMENTS GAIN Fig.7 GAIN Control Input GAIN Adjustment 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 level control is not plugged in until after the master gain control is set.
Page 15 25Hz 250Hz Fig.9 Low Pass Control LPF (Low Pass Filter) Adjustment The crossover frequency adjustment ﬁlters out frequencies that you don’t want your subwoofer(s) to repro- duce. Using the LPF control, adjust the Low Pass Frequency to limit the amount of mid range you want going to your woofer(s).
Page 16 Fig.11 Connection with RJ12 Jack REMOTE LEVEL Controller Connection Your PowerBass Xtreme Class D amp includes a Remote Level control module. It uses standard telephone wire and telephone RJ12 connectors. To connect the Remote Level Control to the ampliﬁer, simply insert one end of the 6-pin telephone plug into the REMOTE LEVEL port.

Page 21 The XMA-2000D minimum speaker impedance is 1 ohm. Both subwoofer OUTPUT 1 and OUTPUT 2 are internally paralleled, thus a minimum impedance of 2 ohms is required when using more than one of the outputs. If you are unsure of calculating impedance loads please consult your PowerBass Xtreme dealer before damaging the ampliﬁer.
