lookin at buying a subwoofer i want good quality sound thats fairly loud would prefer the amp to be built into the sub but not too bothered if i can get both sub and amp for under £200 im currently looking at the Fli Ft12 which is 2x 1000W fli subs with a built in amp lowest price iv seen is £180. Anybody got any suggesting or if any one has the fli sub then any reviews on it would be good also.
