PAC LC-1 Universal Car Amp Bass Knob Audio Component

Universal Car Amplifier Bass Knob

The PAC LC-1 is a remote level controller designed to adjust the volume of any RCA line-level signal in a car audio system. It adds dedicated subwoofer level control to any head unit, allowing fine-tuning of bass output directly from the driver's seat. The compact housing mounts virtually anywhere for convenient fingertip access. Simple in-and-out connections require no additional wiring.

Installers Adding Subwoofer Control

This component suits installers or enthusiasts who need independent volume balance for a subwoofer amplifier without replacing the factory or aftermarket head unit. It works with any amplified system that uses stereo RCA connections for signal input. Builders whose amplifiers already include a wired remote level port, or those requiring digital signal processing, should look at alternative solutions.

Stereo RCA Pass-Through Level Control

The single specification that decides fit is the stereo RCA input and output pair combined with a rotary level knob. The unit sits inline between the source unit and amplifier, attenuating the signal without active processing or external power. Verify that the signal path uses RCA connectors and that a passive, in-line attenuator matches the system design.
