I listen to alot of different music and this system really rocks. I don't listen much to bass tracks, but it plays those surprisingly well for 8's. I have 4 6x9 Kappas in the doors so I already have fairly good bass response, but the subs really fill in the bottom. I would be very careful selecting subs as I tried Infinity Kappas (pre-Perfects) and listened to Kicker Solos before the JL's. Not many subs will go into a small enough box to fit easily on the left side. My boxes are only about .27 cu ft.
The metal on the package shelf is fairly thin, I cut it with a jig saw.
