The JL Audio RBC-1 remote bass control (sold here as TMP Global SKU JLM-RBC-1) gives you convenient, on-the-fly bass adjustment from the helm or dash by connecting to compatible JL Audio amplifiers equipped with a Remote Bass port.

Depending on the amplifier model, the RBC-1 works as either (1) a remote level (attenuator) control or (2) a remote Bass EQ boost control that overrides/defeats the amplifiers onboard Boost knob.
