MEMPHIS AUDIO SMC2A App Controlled Hideaway Head Unit

The Headless Unit

The SMC2A is an extremely innovative solution for creating a complete audio experience in your vehicle without the need to alter your vehicle’s dash to accommodate an aftermarket head unit. Much more than a simple Bluetooth controller, this is an entire head unit packed into a hideaway box. The SMC2A features a built-in 50×4 amplifier, 5  source options, and front /rear /subwoofer RCA outputs allowing you to build your entire system directly off the unit. The hideaway box is controlled via the Memphis APP  allowing you to control your EQ, AM/FM presets, RGB LEDs, and more. The attached wired remote fits in standard knock-out locations but is not required. This is the ultimate Powersports, marine, hot rod, and classic car audio integration where you don’t want to alter the appearance of your dash.
