Thanks for chiming in Dave, actually our little unit is quite sophisticated, it has 2 pairs of pre-amp outs, USB input (for flash drive), 2 aux inputs (front and rear), remote turn on / amp turn on lead--- samsung mp3/wma decoder, all in a radio body that is only 4" wide! we've had some of our customers that have american muscle cars put together some sophisticated systems with 4 and 5 channnel amps (which already handle most of the crossover processing). Our radio caters to customers that want exactly what you mentioned, the look of a shafted radio, but with modern features that blends into the dash well. Thanks, Michael
