You can get away with a small 100W Amp High currant Amp of your preference and make your self a 10" band pass box for all the thump your looking for. There the smallest design with the most bass you'll ever get, the only down fall is that the band pass box is tuned to a low frequancy so you need to upgrade the rest of your speakers to compensate for the mids and highs. But worth the band pass box system.
