Take complete command of your soundtrack on the water or across rugged trails with the Memphis Audio SBT4 controller. Built tough for high-vibe adventures, its heavy-duty rotary dial lets you tweak volume and tracks smoothly even when things get bouncy.

Switch seamlessly between Bluetooth streaming, AUX, and USB charging with a vibrant RGB LED backlit knob that glows to display your active source. The hideaway marine-grade control box delivers extended wireless range, making flexible flush, surface, or bar mounting a breeze.
