Kicker ZXMRLC vs Kicker ZXRC

[jstenger]

Other than obvious differences like dual zone and RCA plugs, what is the difference between these two controllers?

Thanks

The ZXM-RLC is a dual-zone volume control and 9V line-driver. The RC is the optional Bass-Level control knob that works with the Kicker Mono amps and many of the full-range amps when used in lo-pass to drive a sub-woofer. Although the look similar and work similar in terms of rotating a knob, they do not work the same and the control knobs are not interchangeable.
