PLC-U Bass Control

The Rockford Fosgate PLC-U is a universal level remote control for convenient volume control of audio signals. It allows you to individually adjust the signal level—for example, to control a subwoofer—directly from the dashboard or center console.

Thanks to its high-quality audio potentiometer, the PLC-U offers smooth and precise level control across the entire rotation range. The control is integrated directly into the RCA signal path and can therefore be used with any amplifier model.

The PLC-U offers exceptional flexibility thanks to its various mounting options. In addition to the standard flush-mount installation with two different rotary knobs, it can also be mounted under the dashboard or in a switch housing. The switch version also features an integrated 3.5-mm AUX jack for connecting external audio sources.
