XL-400.1D XL-600.1D XL POWERSPORT CLASS D MONO 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.
AMPLIFIERS Thank you and Congratulations Thank you for your decision to purchase a PowerBass USA Xtreme mobile amplifier! Our new mini amplifiers are the result of extensive engineering, testing, and bullet proof construction. Their versatility enables compatibility with optional signal and audio processors. These high quality MOSFET amplifiers may be configured to allow maximum flexibility in designing different types of speaker systems.

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. Disconnect the negative (-) lead from your vehicles battery. Locate all fuel lines, brake lines, oil lines, and electrical cables when planning the install.
MOUNTING LOCATION The XL Series amplifiers have a conformal coating applied to the PC board. This coating makes them resistant to water and dust—however they are not waterproof. Therefore, care should still be taken to protect the amplifier from water and find a mounting location that is not likely to get wet. Take care not to mount in a vehicle/ vessel where it can cause interference with the factory installed electronic devices.
CONTROL PANEL LAYOUT Fig.2 Panel Layout NOTE: Panel Layout and Controls may differ by model. 1. HIGH/LOW INPUT Use this Low Level 4-pin Molex style input is where the wiring harness plugs in for the Low Level 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. However, this input can accept levels up to 10Vrms. 2. AUX Input Jack This 1/8-inch (3.
4. SUBSONIC Control This control is continuously adjustable from 10Hz through 50Hz at 12dB per octave to provide an extra level of speaker protection from bass robbing power at unheard frequencies. 5. BASS EQ Control This equalization circuit is used to enhance the low frequency response of the vehicle’s interior. With up to 18dB of boost centered at 45Hz, the BASS EQ can be adjusted to meet your own personal taste. 6.
FUSE-IMPORTANT Due to the limited space on the XL amplifier chassis they do NOT come with internal fusing! Instead we have included an in-line fuse holder that can be connected directly to the BATT+ input on the amplifier. Please note the proper ampere fuse for each model are listed below. Never replace a fuse with a higher rating then what is listed. XL-400.1D XL-600.
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. Your PowerBass Xtreme Class D amp will draw large levels of current, so use the largest gauge power/ground cable as possible.
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. The use of an inline fuse or circuit breaker is a must; this will prevent the risk of a potential fire caused by a short in your power cable.
Proper Ground Connection For UTVs, Motorcycles or Boats Fig.5 Proper Ground Connection For UTVs, Motorcycles or Boats REM (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 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. Be extra careful when routing your RCA audio interconnect cables. Car environments are notorious for poorly insulated wires.
HIGH LEVEL SPEAKER LEVEL WIRING Alternate radio setup White (Solid) = Left + White / Black (Striped) = Left Grey (Solid) = Right + Grey / Black (Striped) = Right - Fig.7 High Level / Speaker Level Input 1) Cut RCA Plugs off at the black heatshrink in the middle of the pigtail wires. 2) Connect the wires from the speaker output of the radio to the white and grey wires of the amplifier input wires using the color codes in above drawing.
AUX INPUT WIRING Typical 2 amplifier setup Fig.8 AUX Input using 1/8" (3.5mm) AUX (MP3 / PORTABLE DEVICE) 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. Above is a typical two amplifier system—a multi-channel amplifier (our 2-channel XL-250.2 or our 4-channel XL-800.
BLUETOOTH INPUT WIRING Typical 2 amplifier setup Fig.9 AUX Input using 1/8" (3.5mm) XL-BTR1 as a Source The XL Powersport Series amplifiers all feature a AUX source input. This allows you to use our XL-BTR1 (pictured) or XL-BTRS, instead of a traditional radio as your music source. Above is a typical two amplifier system—a multi-channel amplifier (our 2-channel XL-250.2 or our 4-4-channel XL-800.4) to power the full range speakers and a mono bass amplifier (our mono XL-400.1 XL-600.
SET UP ADJUSTMENTS Input GAIN Adjustment GAIN Fig.10 GAIN Control MIN MAX 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: 1. Make sure that the remote level control is not plugged in until after the master gain control is set. 2. Set the GAIN control on the amplifier to Min (completely counter clock wise). 3.
Fig.13 Bass EQ Control 0dB +18dB BASS EQ Control This special feature is designed to provide you more powerful sound quality, and it allows you to increase the bass output up to +18dB at 45Hz. Keep in mind that more is not always better. Setting the control to the max (18dB) will stress the amplifier and the speakers and could result in damage. NOTE: More is not always better. By turning the BASS EQ all the way up to +18dB you can overwork the amplifier and send the unit into thermal protection. Fig.
