Dual Link Power Doubling Circuit (Amp-to-Amp Bridged at 2 ohm minimum) 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 Own- ers 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 Amplifier Due to the high power output of the PowerBass Autosound 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 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.
Page 6: Control Panel Layout
CONTROL PANEL LAYOUT Fig.2 Panel Layout 1. POWER/STATUS Indicator The BLUE L.E.D. lights up when the power is on. This L.E.D. turns RED constantly or flashes when the built-in protection circuitry is activated. This indicates a problem with the system in relation to the amplifier (see Troubleshooting Tips page 21).
Page 7 10. BRIDGED CONNECTION Port (RJ45 Jack) For linking two of the same model PowerBass Autosound Class D amps together. Connect the INPUT of the MASTER to a suitable source via a standard telephone wire with RJ45 modular connectors to the jack on the SLAVE amplifier.
Page 8 16. REM (Remote Input Terminal) All PowerBass AutoSound 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.
Page 9 Your PowerBass Autosound 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 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.
Page 11 Insert the stripped (bare) portion of the wire into the terminal and tighten the screw securely. FUSE REQUIREMENTS While the panel on your PowerBass amplifier incorporates 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
RCA INTERCONNECT WIRING Fig.5 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: Set-Up Adjustments
SET UP ADJUSTMENTS Input GAIN Adjustment GAIN Fig.6 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 14 Fig.10 Connection with RJ45 Jack REMOTE LEVEL Controller Connection Your PowerBass Autosound Class D amp includes a Remote Level control module. It uses standard telephone wire and telephone RJ-45 connectors. To connect the Remote Level Control to the amplifier, simply insert one end of the telephone plug into the REMOTE LEVEL port.
Page 15 SPEAKER WIRING AND CONFIGURATIONS Speaker Load Keep in mind your PowerBass Autosound Class D amp is a high power amplifier and not a high current amplifier. In other words it requires a minimum impedance of 1 ohm. If you are unsure of calculating impedance loads please consult your Authorized PowerBass Autosound Dealer before damaging your amplifier.

NOTE: If the Status L.E.D. is activated and glows RED with no speakers connected to the amplifier, and all the power connections are correct, this would indicate an internal problem with the ampli- fier. Contact PowerBass USA or your local dealer.
