I drive an 82 corvette and I would like to update the stereo. I bought 2 10'' 600w pioneer subs and an orion 250 hcca digital reference amp. I would like to hook up the amp to the rear speakers and the subs. And leave the radio to power the 2 speakers in the front. If I do this what kind of in dash receiver would I need to buy? Oh and I would like it to be ipod compatible. (I would love for it to be under $100 or so) Thanks!
