this guys are pretty good as far as knowing what they are talking about. Fabrication is about the best i have seen in this area. Their work is amazing. Store setup is a plus also with amps in a glass floor and with the usual HU board and subs in the wall, also with the midrange speakers in the wall. They will work with you on the price and give good advice. DB show is pretty decent that i went to last year about the best one i have been to. I purchased my zapco amp from them and will continue to do business with them.
they sell: Memphis, punch, eclipse, diamond audio, and there might be jus 1 or 2 more for the HU's
