Here is a link to the ipod cable I bought:
http://www.amazon.com/Metra-AIP-RCA-...d+to+rca+cable . I ran the RCA cables to a mgain control knob (like you would use to control sub input- RCA in and out), then ran that back the amp (with splitters- it's a 4 channel amp). I am sure the sonic quality can be outdone, but the price was right. The rest of my system is 6 1/2 Pioneer seperates in the doors (tweeters in the a-pillars), and Pioneer 6x9's in Jeff's (bigblock73) 6x9 brackets. Everything except the brackets and ipod cable were leftovers from a buddy and it gets the job done. The best part is that it is mostly hidden, and I can put an 8 track player back in the dash. That was really my whole goal all along.
