JBL BassPro Go is a powered subwoofer designed to easily mount and charge in any vehicle. It acts as a subwoofer or a full-range speaker in the vehicle; and, with its quick-disconnect feature, becomes a portable Bluetooth speaker. It features easy-to-use controls and a convenient safety cover to help protect the speaker when used out of the vehicle, and to provide an IPx5 marine rating.

IMPORTANT: Disconnect the vehicle’s negative (–) battery terminal before beginning the installation.

  • Wear protective eyewear when using tools.
  • Choose a safe mounting location. Check clearances on both sides of the location. Be sure that screws will not puncture brake or fuel lines or wiring harnesses, and that wire routing will not interfere with vehicle operation. Use caution when drilling or cutting.
  • When making electrical connections, make sure they are secure and properly insulated.
  • Using the dock as a template, mark the locations of the holes on the mounting surface.
  • Drill pilot holes in the mounting surface.
  • Attach the dock to the mounting surface with the included sheet metal screws and washers.
Mounting the Dock in the Vehicle

Use the included sheet metal screws to secure the dock to the mounting surface in the vehicle. Ensure that the included wire is long enough to reach the desired mounting location before securing the dock.

Installation & Wiring 01

Mounting the Speaker in the Dock
  1. Pull the handle out.
    Installation & Wiring 02
  2. Rest one corner of the speaker on the dock at a slight angle to get the speaker seated.
  3. Rotate the speaker until it is completely in place in the dock.
    Installation & Wiring 03
  4. Release the handle to finish securing in place.

NOTE: It will be easiest to connect the wire harness before mounting the speaker in the dock.

Power and Ground Connections in the Vehicle

Installation & Wiring 04

  1. Power: Connect the red +12V power wire in the wire harness to the positive terminal of the vehicle battery. Install a 20A fuse and fuse holder within 18″ (457mm) of the battery.
  2. Ground: Connect the black GND wire in the wire harness to bare metal of the vehicle’s chassis, such as at a seat belt bolt.
    NOTE: If possible, remove any paint from the chassis for best contact. It is recommended to use a star washer below the ring connector for a secure connection.
  3. Remote-In: Connect the blue remote turn-on wire in the wire harness to the “Remote Out” lead of the source unit, if using low-level signal inputs.

NOTE: 12V ACC turn-on is the preferred method. If you are using high-level signal inputs (vehicle speaker wires), you can choose to have the DC offset feature or the audio-sensing feature turn the amplifier on. You will not have to connect the remote turn-on wire and can terminate the connection.

Power/Protect Indicators when Connected to the Vehicle

The power button on the control panel indicates the speaker’s modes of operation.

Signal Input in the Vehicle

Line-level inputs: If your source unit offers preamp outputs, connect them to the RCA inputs in the wire harness. Use front or rear preamp outputs for full-range operation, or subwoofer preamp outputs (if available) for subwoofer mode.

Installation & Wiring 05

Note: When using low-level signals and remote turn-on lead, set the “Auto Turn-on” switch to “12V,” and set the speaker’s input level to “LO” in the settings menu (see “setting the input level”). Set the “Auto-on” switch to 2V, 4V, or 6V, whichever most closely matches the voltage of your source unit’s preamp outputs.

High-level inputs: If your source unit does not have line-level outputs, use the supplied high-level input adapters to connect to the speaker output wires of your source unit to the RCA inputs in the wire harness.

Installation & Wiring 06

NOTE: When using high-level signals, set the “Auto Turn-on” switch to “DC” (to turn on when it receives battery power) or “AUDIO” (to turn on when it senses audio signal). Set the input level to “HI1” in the settings menu (see “setting the input level”). If no sound plays, change the input level to “HI2”.

Connecting the Remote Bass Control in the Vehicle

Plug the remote bass controller into the appropriate input in the wire harness. Mount the remote in a convenient location, such as under the dash, using sheet metal screws.
Turn the dial clockwise to increase the bass output, and counterclockwise to decrease the bass output.
NOTE: Remote bass control will only operate in subwoofer mode.

Installation & Wiring 07


In Settings Mode, you can adjust the input level, gain, low-pass crossover, phase control, and bass boost.


NOTE: To enter Full-Range Mode from Subwoofer Mode, press and hold the JBL Connect and Play/Pause buttons for 5 seconds. To switch back to Subwoofer Mode, repeat the same process.

Entering Settings Mode

Press and hold the JBL Connect button and the Bluetooth button for 5 seconds to enter Settings Mode. The power button will illuminate in yellow and an alert will sound. Press the JBL Connect button to toggle between settings. Press the “+” and “–” buttons to change the value of each setting.

Entering Settings Mode

The color of the first LED indicates which setting you are adjusting. The five white LEDs display the value of the adjustment.

Setting the Input Level

When the BassPro Go is docked in your vehicle, you will need to set the input level to accept the type of signal it receives from your source unit. Select level options by pressing the “+” and “–” buttons.

Setting the Gain

When the BassPro Go is docked in your vehicle, you will need to match the gain (input sensitivity) to output of the signal it receives from your source unit. To set the gain:

  1. Start with gain control switch set to 2V.
  2. Choose music with substantial bass content and turn the volume control on your receiver to 75% of its total output.
  3. Increase the gain one step at a time by pressing the “+” button, listening carefully to the bass output, as the LED read out displays each step. To increase the interval of the gain you are adjusting, move the gain control switch to 2V, 4V, or 6V as necessary. If you hear distortion, lower the gain one step at a time by pressing the “–” button until the distortion disappears.
