Just bought an 02 wrx. The car is in its stock condition with the stock 6 disk head unit. I have an acendant audio 15" ported and a elemntal designs amp(set up kicks ass ). I researched using the stock head unit but the wire splicing and what not will not cut it(correct me if im wrong). I would like the best head unit for under 500 dollars that money can buy me. I have an xm satalite radio subscription and would like to put it to use without the protable thing. Any sugestions. I would like to keep the flow of the size of the stock head unit if posible(Which may not be the best option) and run satalite radio without the prortable divice. Oh and I own a microsoft zune which was audio outs like a tv audio set.
