ahem.. i never said that that amp only produced 150 watts.. i just said 150 watts on a GOOD sub wont do much! so for example 150 watts on a jl w7. wont do much right? right! i never said anythin about that rockford amp or anythin. the post above mine says "150 watts and a 12 inch sub sounds like overkill for me" and i replied with 150 watts isnt goin to do much on a good sub. he also said at the first thread if you actually read it that he does not need to be heard a block away so a w7 would be a lil too much for his use. and about underpowering subs ok i might be wrong about that but ive had my share of underpowered subs and ended up wreckin them. my system is a 2 12" infinity kappa perfect dvc running off a jbl bp 600.1.. and ive also got plenty of juice for that sub.
