JL Audio amplifiers come equipped with bass-boost circuitry, allowing you to fine-tune the low-frequency impact in your vehicle. The RBC-1 wired remote bass control is compatible with all of JL Audio's A-Series, G-Series, RD Series, mono JX-Series, and most Slash v2 amplifiers. With the RBC-1 controller, you have the flexibility to adjust the bass output from the driver's seat. Simply mount the controller in a convenient location in the front of your vehicle using the included mounting instructions, hardware, and 18' cable. This setup gives you easy access to dial in the perfect amount of bass to suit your preferences while on the road.
