product description
Universal Fit
Compatibility
CTRLX is amplifier-agnostic. If your amplifier or DSP has a standard RCA input — and almost all do — CTRLX will work with it. No brand lock-in. No proprietary cables. No firmware flashes.
Any Amplifier with RCA
Plugs into the remote-bass / RCA input on the back of your amplifier. The receiver is wired in-line between your head-unit and amp — the wireless half lives in your hand.
Any Class · A / B / D / Mono
Class doesn't matter. Power doesn't matter. If it has an RCA in (mono or stereo), CTRLX speaks to it.
RCA up to 6.5V Max
Tested with high-output head-units, DSPs, and pre-amps. The receiver tolerates up to 6.5 V on the RCA side without distortion.
Mono Bass Channel
Designed specifically for the bass / sub channel. One mono control point — exactly how the amp's existing bass-level pot works.
9 V – 18 V Vehicle Range
Works on 12 V cars, 24 V commercial vehicles, and on the bench with a regulated supply. The voltmeter calibrates inside that range.
No App. No Account.
Pair once at the factory — done. No phone needed. No login. No cloud. The CTRLX Link talks directly between knob and receiver.
If you're wondering
"Will it work with my setup?"
Look at the back of your amplifier. If you see a stereo or mono pair of RCA jacks labelled BASS REMOTE, REMOTE LEVEL, R.E.M., or simply two RCA inputs — CTRLX will plug straight in. We’ve tested it with Pioneer, Kenwood, Alpine, Sony, Hertz, JL Audio, Rockford Fosgate, Audison, Helix, Massive, ARX, DD Audio, and dozens of Indian aftermarket brands. Same answer every time: it works.
Not sure about your specific amp? Send us a photo of the back panel and we’ll confirm before you order.
