I'm not expecting perfect, or even great (or even good?) sound. I have a stock tape deck in a 10 year old Pathfinder. Wind noise, tire noise, rattling of various parts is awful. There's no way I'm spending more than a couple hundred on everything, as there's no way I can really get the acoustics in good shape. I just want dirt cheap and "not total crap."

Of course, since I don't have a CD player, I'd probably end up getting a cheap CD receiver to go with it.

Would it make more sense (sound a lot better?) if I just got a new receiver instead?
