i have a sony headunit now, its 52 x 4, and presonally, i think it sounds great, with my stock pioneer speakers.

the one problem is that it doesnt play to the front right, because i bought it on ebay. i brought it to united radio to get it fixed, they said they fixed it, but they didnt, and i dont want to go through their system again, so im thinkin about another one....

i heard pioneer sounds pretty good, any other suggestions?
