EASY-TO-READ Display: The MM105 stereo’s ultrabright 3.5-inch full-colour LCD display features separate day/night themes for clear visibility in all lighting conditions. While in motion, you’ll appreciate the intuitive user interface and oversized, illuminated control knob along with the large backlit buttons. Four Audio Zones: The stereo’s premium sound is deployed via 4 separate audio zones, each with its own independent control options and subwoofer output, with built-in, selectable low-pass crossover. Volume, tone (bass, midrange, treble) and balance can all be adjusted separately — or linked with zone 1. Max volume levels can be set for each zone. Simple Zone Level Control: The RCA zones feature the JL Audio zero-clipping circuit design with self-limiting tone controls to help prevent speaker damage at high listening levels.
