stay far away from boss and pyle. they are bothe JUNK. they will break a short time down the road. also stay away from crutchfield. they have great service but there prices are a little inflated. just about anything you can get from crutchfield you can get from sonicelectronix for way cheaper. heres a Kenwood deck that should work pretty good for you. its 109$ shipped.
