  • Page 1 XL POWERSPORT FULL RANGE MX 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 3 In the interest of safety, PowerBass USA highly recommends listening at lower volume levels when driving.

  • Page 4: Technical Features

    This amplifier represents the very latest in Class D technology. The XL Series uses the new IR® (International Rectifier) platform which has been under development for the past several years. IR®, a leader in PWM circuit design, has worked in conjunction with PowerBass engineers to produce more stable power output, minimal RF interference and improved sound quality.

  • Page 5: Preparing For Installation

    Soldering iron • Electronic (Rosen not Acid Core) Solder INSTALLATION PRECAUTIONS NOTE: Proceed only if you are a qualified installer, otherwise; see your Authorized PowerBass Dealer to professionally install this amplifier. Always wear protective eyewear when using tools. • Turn off all stereo and other electrical devices before you begin.

  • Page 6: Mounting The Amplifier

    MOUNTING THE AMPLIFIER Fig.1 Mounting Amplifier To keep your PowerBass Xtreme amplifier running at top performance, choosing the proper location is of utmost importance. Both Thermal and Overload protection are built in. In the event of overheating, the amplifier will turn off and only restart when cooled. For this reason the amplifier should be mounted in a location which will allow air to circulate freely.

  • Page 7: Mounting Location

    The best places to mount your amplifier are: The floor of the trunk, under a seat, on the back of the rear seat or a storage compartment will air can circulate. 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 mounting feet to crack.
  • Page 8 XL-2305MX CONTROL PANEL LAYOUT Fig.2 2-Channel Panel Layout NOTE: Panel Layout and Controls may differ by model. 1. Low Level Inputs/Outputs (from left to right) A. LOW LEVEL RCA Inputs Low Level RCA input that connects to source units with RCA line level outputs. A source unit with a minimum input of 250mV is required for proper operation.
  • Page 9 C. 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 your power cable should be used to attach the ground directly to the chassis of the vehicle. Make sure that all of the paint is sanded or scraped away to ensure a quality ground connection.
  • Page 10 XL-4255MX CONTROL PANEL LAYOUT Fig.3 4-Channel 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 11 C. 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 your power cable should be used to attach the ground directly to the chassis of the vehicle. Make sure that all of the paint is sanded or scraped away to ensure a quality ground connection.
  • Page 12 POWER WIRING AND SIGNAL CONNECTIONS *** WARNING *** Disconnect the negative (-) battery terminal before you start any wiring work! The battery of your car audio system must be disconnected until the entire wiring installation is completed. • Use rubber grommets when running cables through any metal or sharp plastic, to prevent accidental shorting or shearing.

  • Page 13: Power Wiring

    POWER WIRING BATT+ (Power) - Red Wire 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 14: Fuse Requirements

    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 an in-line fuse holder and fuse for this purpose.
  • Page 15 SOURCE INTERCONNECT Fig.8 Input using RCA or 1/8" Shielded Cable 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 16 The balanced input of this XL 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 17 3.5mm AUX INPUT/OUTPUT WIRING Typical 2 amplifier setup Fig.10 AUX Input using 1/8" (3.5mm) MP3 or Portable Device as a Source The XL Powersport Series amplifiers all feature a AUX source input. This allows you to substitute a portable music device such as an iPOD, Smartphone, MP3 Player, etc instead of a traditional radio as your music source.

  • Page 18: Set-Up Adjustments

    SET UP ADJUSTMENTS INPUT Gain Adjustment GAIN Fig.11 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).
  • Page 19 Fig.14 High Pass Control (HPF) 40Hz 400Hz HPF (High Pass Filter) Adjustment When you are using coaxial or component speaker system, this allows you to adjust high-pass X-over frequency from 40Hz to 400Hz. To get better sound quality from coaxial or component speaker system, we recommend the frequency should be higher than 80Hz.
