RE: in 12s in a 4th gen.
I run one sony 1200W sub off a JL 250 mono amp. With the amp turned @ about less than half and the Sub control on my Sony deck almost off, it F-in pounds. To be totally honest, it all depends on what your running. If you have crap, expect crap. If you have a quality deck,amp and speaker, you dont need a Jillion watts for it to sound bad @$$.

i agree with chappie. Your speakers/subs are only going to sound as good as whats powering them. If you have a weak amp your going to get a low quality result. The higher quality the power source for the sound system the cleaner power will be made (clean power is basically being able to turn the stereo up to a higher point without the speakers clipping.)
