JL Audio RBC-1 JL Audio amplifiers feature bass-boost circuitry to help you adjust low-frequency impact in your vehicle. The RBC-1 wired remote bass control works with all of JL Audio’s A-Series, G-Series and most Slash v2 amps. You can mount the RBC-1 controller in the front of your vehicle and dial in the amount of bass you want from the driver’s seat — mounting instructions, hardware, and a 18′ cable are included. Connect the RBC-1 to your amp, and it converts the amp’s selectable bass boost (0 or 6 dB) to a variable boost (0 to 12 dB). With the Slash v2 amps, the RBC-1 takes the place of the amp’s boost knob, allowing you to adjust your bass boost from 0 to 15 dB.
