product description

The CTRLX Wireless Bass Knob is a premium wireless bass level controller designed for car audio enthusiasts who want precise subwoofer control without the limitations of a wired remote. Engineered for compatibility with most aftermarket amplifiers featuring RCA inputs, the CTRLX system replaces the traditional wired bass knob with a compact wireless controller, providing a clean installation while maintaining responsive and accurate bass adjustment.

The system consists of a wireless transmitter (bass knob) and a compact receiver module that installs between the audio source and amplifier. The receiver is powered from a standard 12V DC vehicle electrical system and features RCA input and output connections for seamless integration into existing car audio systems. The transmitter and receiver are factory paired, allowing quick installation with no complicated setup or programming required.

The wireless bass knob features a bright OLED display that provides real-time information including bass level, connection status, vehicle battery voltage, and controller battery level. The display remains easy to read in both daylight and nighttime driving conditions. The rechargeable controller charges through a modern USB-C port, eliminating the need for disposable batteries while providing long operating life.

CTRLX utilizes a low-latency wireless communication system designed specifically for automotive environments. This ensures smooth, responsive bass adjustments without the signal delays commonly associated with generic wireless devices. Intelligent pairing and automatic reconnection allow the controller to reconnect to the receiver whenever the vehicle is powered on.

The controller offers smooth, precise adjustment of the subwoofer output level, allowing users to increase bass for music that demands more low-frequency impact or reduce bass for spoken audio and everyday listening. Unlike traditional wired remote knobs that require routing cables throughout the vehicle, the wireless design significantly reduces installation time while providing greater flexibility for controller placement.

Additional intelligent features include automatic sleep mode to conserve battery power, fast wake-up when the vehicle is started, and stable wireless performance inside the vehicle cabin. The compact receiver can be mounted discreetly behind the dashboard or near the amplifier, maintaining a clean, professional installation.

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 REMOTEREMOTE LEVELR.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.
