  • Page 1: Owners Manual

    XL POWERSPORT 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 In the interest of safety, PowerBass USA highly recommends listening at lower volume levels when driving.

  • Page 3: Technical Features

    Installation of PowerBass mobile amplifiers requires detailed knowledge of electronics wiring and proper speaker imped- ance. 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 4: Installation Precautions

    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.

  • Page 5: Mounting Location

    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. NOTE: Do not use a drill with driver bit to mount the amplifier. Excessive force could cause the plastic mounting feet to crack.

    CONTROL PANEL LAYOUT Fig.2 Panel Layout NOTE: Panel Layout and Controls may differ by model. 1. POWER/STATUS Indicator This clear LED lights Blue when the power is on—or turns Red constantly when the built-in protection circuitry is activated. Red indicates a problem with the system in relation to the amplifier (See Troubleshooting Tips).
  • Page 7 10. 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 an electronic antenna output, or a remote output. If this is not avail-...

  • 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

    Insert the stripped (bare) portion of the wire into the terminal and tighten the screw securely. FUSE REQUIREMENTS Due to the small size of the PowerBass XL series amplifiers, no fuses are incorporated into the panels that normally protect the unit from excessive current. Instead we have included a wired loop in-line fuse holder and fuse for this purpose.

  • Page 12: Rca Interconnect Wiring

    RCA INTERCONNECT WIRING Traditional radio setup Fig.6 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.
  • Page 13 Smartphone, MP3 Player, etc instead of a traditional radio as your music source. Above is a typical two amplifier system—a multi-channel amplifier (our 2-channel XL-2200M or our 4-channel XL-4160M) to power the full range speakers and a mono bass amplifier (our mono XL-350DM or XL-600DM) to power the subwoofer(s).

  • Page 14: Set-Up Adjustments

    SET UP ADJUSTMENTS Input GAIN Adjustment GAIN Fig.8 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 level control is not plugged in until after the master gain control is set.
  • Page 15 Fig.12 Connection with RJ25 Jack REMOTE LEVEL Controller Connection Your PowerBass Xtreme Class D amp includes a Remote Level control module. It uses standard telephone wire and telephone RJ25 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 16 SPEAKER WIRING AND CONFIGURATIONS Bridging Although the XL-350DM and XL-600DM have two sets of subwoofer outputs, they are mono and the outputs cannot be bridged. The two sets of outputs are in parallel inside the amp to a single channel. This allows easier wiring during the installation of multiple voice coils or woofers.
  • Page 17 Speaker Load Keep in mind your PowerBass Xtreme Class D amplifier is a High Power Amplifier and not a high current amplifier. In other words it requires a minimum impedance of 2-ohms (1-ohm for the XL-600DM). Both sub- woofer outputs are internally paralleled, thus a minimum impedance of 4-ohms (2-ohms for the XL-600DM) is required when using more than one of the subwoofer outputs.
