You can mount this remote almost anywhere so you can easily reach it to make adjustments. It's ideal for classic cars where the radio is often installed out of sight, or for larger vehicles like an RV or tour bus. The remote connects between your aftermarket receiver and amplifier, via RCA patch cables (not included), adding a volume control in a more convenient and visible location than the control on your receiver. The PLC-U features a linear-taper rotary control that intuitively matches the program volume to the knob's rotary position — 12 o'clock position is half volume, 3 o'clock is three-quarters full, for example. Custom options and an auxiliary input The PLC-U comes with three mounting options (panel, under dash, and panel knockout) and two different size knobs to match the look and feel of your vehicle's interior. The panel knockout bracket includes an auxiliary 3.5 mm input jack that allows you to play music from a portable device. Warranty: 1 year.
