got a ? I got a yzen 450 the other day with a superbass pro box. the thing is the box came with sum "probox rocks" speakers in it. i had never heard of them before but i know the guys real well and one of them has the same set up with a set of 12s in it and hes getting like 155db. i didnt believe it till i heard it. the thing is that my speakers after being hooked up will kill ur body with rap but with rock songs it only hits on certain songs like tool-prison sex and some manson songs. whats the deal with that i mean when i listen to alice in chains-rooster i should have trouble seing why is it hitting sssooooooo freaking hard with rap and sounding like its dying for power with everything else??????
