Memphis Audio MXABTRK Rocker Carling Switch Style Bluetooth Controller w/Aux/USB

The MXABTRK is a Bluetooth audio controller that mounts into a standard Carling rocker switch opening, which means it goes where a switch already lives on a side-by-side, boat, or utility vehicle dash. No head unit, no bracket, no cutting a new hole.

It streams over Bluetooth 4.1 and sends a 5 volt preamp signal out over 3.5mm, which is enough to feed a powersports amplifier cleanly. Front panel controls cover volume up and down, track forward and back, pause, and aux switching, and volume works on both the Bluetooth and aux sources. A 3.5mm aux input handles anything streaming does not, and a remote output turns the amplifier on and off with the controller so nothing draws current when the machine is parked.

A 1 amp USB port keeps a phone charged while it streams, which is the difference between music all day and music until lunch. At 0.83 inches wide by 1.45 inches high, the face sits flush with the rest of the switch panel.

Use it as the source for a simple two-speaker-plus-amp setup, as a second control point on a larger build, or as a replacement for a phone sliding around the console. For open cab machines where a traditional head unit makes no sense, this is the practical way to run audio.
