I've been looking into some more car audio recently. I found a lot of stuff online and on ebay etc, but I don't really know how good any of it is. Some of the people on ebay want you to think its great stuff. I found this guy selling head units, that he claimed were the greatest thing he's found. He didn't have much info, but I looked them up, and they were 25x4's. That sucks! Anybody else know stuff that would benefit me?
