alright, so after looking around online and through the stores this week, I went to Best Buy tonight and picked up a nice Sony head unit that was on sale and had a free install on top of it. Well, I buy the thing, walk outside to the bay where they install car audio stuff to make an appointment for tomorrow, and after talking to the guy for a minute he is kind enough to inform me that he will not install my head unit in my car (2000 volvo S40), because it requires too much wiring [each speaker has a small amp, as opposed to the amp being in the stock head unit], even though I asked about this problem before I bought the damn thing. He suggests I try tweeter instead. Should I head back tomorrow and try to get them to install it anyways, risking paying more for "custom" installation; or just return the thing and pay more elsewhere?
