    Remote Gain Control (Included) 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 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.

  • Page 6: Control Panel Layout

    CONTROL PANEL LAYOUT Fig.2 Panel Layout 1. POWER Indicator The clear L.E.D. lights BLUE when the power is on. 2. STATUS Indicator This L.E.D. turns RED when the built-in protection circuitry is activated. This indicates a problem with the system in relation to the amplifier (see Troubleshooting Tips). 3.
  • Page 7 5. LINE OUT (RCA) Jacks RCA style pass through output jacks allow for a signal to be sent to other amplifiers in a daisy-chain configura- tion. Only one Remote Bass Control can be used when multiple bass amplifiers are connected. 6.
  • Page 8 15. 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 avail- able 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 Now it’s time to connect the power and ground cables to the amplifier. Cut both cables to length. Strip off 1/2 inch (12mm) of the insulation so that the bare wire fits all the way in the terminal block on the side panel of the amplifier, seating it firmly so no bare wire is exposed.

  • Page 12: Rca Interconnect Wiring

    RCA INTERCONNECT WIRING Fig.4 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 provides better noise rejection.
  • Page 13 HIGH LEVEL CONNECTIONS (Optional) High Level inputs have been included to connect the amplifier to a radio without low-level outputs (i.e. factory radio). This connection will allow you to connect directly to the speaker output of the radio without the need of an external adapter.

  • Page 14: Set-Up Adjustments

    SET UP ADJUSTMENTS Input Gain Adjustment Fig.5 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 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 16 Speaker Load Keep in mind your PowerBass Autosound Class D amp is a high power amplifier and not a high current ampli- fier. 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.

  • Page 18 Maintaining proper impedance is critical when wiring the Class D model amplifiers. Improper wiring can cause severe damage to BOTH the woofer and the amplifier. 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.
