Had them replace a stock subwoofer for my car. I already had an 4 way amp running the front and back door speakers. They fit a kicker 8"" sub and rerouted the amp back to the sub and front speakers only. Also purchased speaker damping material for the sub. They did an excellent job listening to what I wanted knowing I did my homework about my vehicle. They ran a quote of $310 and ended up paying $269. I would do business with them anytime.
