I've already decided that I'm going to get a pair of Kenwood KFC-W3003 subs. I found a seller on ebay who has a bunch of car audio auctions, and a lot of feedback and he's selling a lot of stuff below retail. The name is Scala1. I'd like to buy all of my stuff from him to possibly get a discount. Anybody deal with him? Anyway, what type of amp should I get to power these bad boys? I was going to buy a Rockford Fosgate, but they seem kinda expensive, and I'm all confused about the bridged and other such terminology that goes along with the amplifers. Help me out
