I like realy loud music, and the fjammer and 9 speaker setup has worked great for me. I did put in 2 12"kicker cvr subs, but they took u wayy to much space. So I had a local shop build me a very narrow wedge for one, that sits in the back. I had to modify it a little because it was not deep enough. I still have my same amp, so I definitely get enough bass out of it. I will post pics if I can remember
