JL Audio M-RBC-1

This M-RBC-1 wired remote controls the output level of JL Audio's HX-Series and MHX-Series amps — amps designed for powersport and marine applications that need a wired remote built for rough conditions. The remote's cable incorporates waterproof gaskets to keep the electrical connections dry, so you can mount the M-RBC-1 controller in the front of your vehicle or boat, then dial in the amount of bass you want from the driver's seat — mounting instructions, hardware, and an 18-foot cable are included.
