Remote Level Control Port(for optional controller) 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 4: Installation Precautions
MOUNTING THE AMPLIFIER Fig.1 Mounting Amplifier Due to the high power output of the PowerBass Autosound mono 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 the driver’s 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. -

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 an electric antenna output, or a remote output. If this is not available you can wire to the ACC position on the key.
- Page 8 Your PowerBass Autosound Mono amp will draw large levels of current, so use the largest gauge power/ ground cable possible. Using too small of power cable can result in unnecessary over-heating of the ampli- fier, distortion at high volume levels and might even cause the thermal protection circuitry to shut-off the amplifier.
- Page 9 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 10 REM on the amplifier. 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 13: Set-Up Adjustments
SET UP ADJUSTMENTS Fig.5 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 gain control is not plugged in until after the master gain control is set. Set the GAIN control on the amplifier to Min (completely counter clock wise). - Page 14 BASS EQ 12 dB Fig.8 Selectable Bass EQ Bass EQ Switch This special feature is designed to provide you more powerful sound quality, and it allows you to boost the Bass EQ to 12dB. Keep in mind that more is not always better. Setting the control to the max (12dB) will stress the amplifier and the speakers and could result in damage.
- 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 this amplifier requires a minimum impendance of 1-Ohm mono to operate trouble free.

Detailed wiring diagrams are supplied with all PowerBass woofers. IF YOU ARE NOT EXPERIENCED OR UNCOMFORTABLE READING THE WIRING DIAGRAMS CONSULT YOUR AUTHORIZED POWERBASS DEALER BEFORE YOU ATTEMPT TO WIRE THE SYSTEM.
