Setup & Installation
Safety Precautions
Always disconnect the vehicle's negative battery terminal before beginning any electrical installation. Ensure all wiring is correctly routed and securely fastened to prevent damage or interference. Professional installation is highly recommended for optimal performance and safety.
Wiring Connections

- Power (+12V): Connect the +12V terminal to the positive terminal of your vehicle's battery.
- Remote (REM): Connect the REM terminal to the remote turn-on output of your head unit or an accessory switch that provides +12V when the ignition is on.
- Ground (GND): Connect the GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a secure, low-resistance connection.
Audio Inputs
- Low Level Inputs (RCA): Use RCA interconnect cables to link the BAB10 with the RCA outputs of your source unit. Most aftermarket radios have multiple pairs of RCA outputs.
- High Level Inputs: Speaker level inputs are used to connect the BAB10 to your factory radio or an aftermarket radio that does not have low-level (RCA) outputs.
Remote Subwoofer Control
Connect the included BASS Knob to the "REMOTE" port on the subwoofer's control panel. This allows for convenient bass level adjustment from the driver's seat.
Mounting
The low-profile design of the BAB10 allows for flexible mounting options. It can be placed under a seat or in the trunk, depending on available space in your vehicle. Ensure the subwoofer is securely mounted using appropriate hardware to prevent movement during vehicle operation.

Operating Controls
- GAIN (Input Gain): Adjusts the input sensitivity of the amplifier to match the output level of your source unit. Start with the gain at minimum and slowly increase until desired volume is achieved without distortion.
- LPF (Low-Pass Filter): Controls the upper frequency limit of the subwoofer. Adjustable from 50Hz to 150Hz. Set this to prevent higher frequencies from being played by the subwoofer, ensuring clear bass reproduction.
- BASS (Bass Boost): Increases the bass output at 45Hz, adjustable from 0dB to +18dB. Use this to enhance the low-frequency impact.
- PHASE: A switch to adjust the phase of the subwoofer output between 0° and 180°. This helps to synchronize the subwoofer's output with other speakers in the vehicle, optimizing bass response.
- PWR (Power LED): Illuminates green when the subwoofer is powered on and operating correctly.
- PRT (Protect LED): Illuminates red if the amplifier detects a fault condition (e.g., overheating, short circuit) and enters protection mode.
- Remote Subwoofer Control (BASS Knob): An external wired control that allows you to adjust the subwoofer's output level from the driver's seat.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the subwoofer. Avoid abrasive cleaners or solvents.
- Fuse Replacement: The subwoofer is equipped with a replaceable 25A fuse. If the power LED does not illuminate, check and replace the fuse with one of the same type and rating.
- Regular Checks: Periodically check all wiring connections for tightness and ensure no wires are frayed or damaged.
Troubleshooting
- No Power (PWR LED off):
- Check the +12V, Remote, and Ground connections for proper installation and continuity.
- Verify the fuse is intact and correctly installed.
- Ensure the vehicle's battery has sufficient charge.
- Protection Mode (PRT LED on):
- Check speaker wiring for short circuits.
- Ensure proper ventilation around the subwoofer to prevent overheating.
- Reduce the input gain or bass boost settings.
- No Sound:
- Verify all wiring connections (power, ground, remote, audio inputs).
- Check the source unit's volume and output settings.
- Ensure the subwoofer's gain is not set too low.
- If using high-level inputs, ensure the auto-start feature is enabled or the remote wire is connected.
- Distorted Sound:
- Reduce the gain setting on the subwoofer and/or the source unit.
- Adjust the bass boost and LPF settings.
- Check for damaged speaker wires or faulty audio inputs.
- Weak Bass:
- Increase the gain setting.
- Adjust the LPF to a higher frequency.
- Increase the bass boost.
- Check the phase switch for optimal alignment with other speakers.
