    Low Level Line Inputs and Outputs 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

    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 electrical devices before you begin. • Disconnect the negative (-) lead from your vehicles battery.

  • Page 5: Mounting Location

    The amplifier should be protected from exposure to moisture and direct sunlight. The best places to mount your amplifier are: 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.

  • Page 6: Control Panel Layout

    CONTROL PANEL LAYOUT Fig.2 Panel Layout NOTE: Panel Layout and Controls may differ by model. 1. Line OUTPUT (RCA) Jacks RCA style pass through output jacks allow for a signal to be sent to other amplifiers. 2. Line INPUT (RCA) Jacks These RCA style input jacks are for use with source units that have RCA line level outputs.
  • Page 7 8. REMOTE LEVEL Port This is the connector port for the optional Remote Level Control. Now the amplifiers secondary gain circuit can be adjusted from the driver’s seat. (See your local PowerBass dealer and ask for model PB-GAIN1 sold separately.) 9.
  • Page 8 14. REM (Remote Input Connection) 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 9 Fig.3 Power Input Connection These amplifiers are designed to work within a 9 to 17 volt DC range. Before any wires are connected, the vehicles electrical system should be checked for correct voltage supply with the help of a voltmeter. First, check the voltage at the battery with the ignition in the OFF position.
  • Page 10 GND (Ground) When grounding your amplifier, locate a metal area close to the amplifier that is good source of ground (preferable the floor pan). Once again, investigate the area you wish to use for electrical wires, vacuum lines, and brake or fuel lines. Use either a wire brush or sandpaper to eliminate unwanted paint for better contact of the ground.
  • Page 11 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. The value of this fuse (or circuit breaker) should be no greater than the sum of the fuses found on all of the equipment being connected to that power wire.

    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 three simple steps: Set the volume of GAIN on the amplifier to Min (completely counter clock wise).

  • Page 14: Input Mode

    “LPF”. REMOTE LEVEL Port This is for the optional Remote Gain Control (part# PB-GAIN1 see your Authorized PowerBass dealer for details). Plugging in the remote Bass Control overrides the BASS EQ Control on the amplifier side panel.
  • Page 15 SPECIAL CONTROLS FOR THE ASA3-1200.2 The following instructions apply to the model ASA3-1200.2 only. You will not find this switch on any of the other models in this series. Fig.12 Sub Sonic Adjustment SUB SONIC Switch When set to the ON position, the sub sonic control will filter out all frequencies below 28 Hz from going to the speaker(s).

  • Page 16: Speaker Wiring

    SPEAKER WIRING AND CONFIGURATIONS Speaker Load Keep in mind your PowerBass Autosound amplifier is a high power amplifier and not a high current amplifier. In other words this amplifier requires a minimum impedance of 2 ohms STEREO and 4 ohms bridged MONO to operate trouble free.
