DB Drive is the way to go. The PL series is a sweet set up about 750 rms a peice. BEAT, but still have good sound quality, and cover a large frequency range. Box size is small compared to other brands with great results. If the money is tigh go with their sister company Quantum audio. My boss has 2 12" DB Drive subs and one of myt boys has the same set up Quantum. the DB drive takes it by 3db, which depending on you style of music and how trained your ear is, is not a audible difference
