You will still get the rattles. I was playing with different setups back in '01 and even a 8" sub with a 500watt RMS amp was causing issues. I then stripped the car to the shell and sound deadened the shiet out of it. When all was said and done, my 2K watt system did not produce 1 rattle.mkell said:That's what I expected. I know that in some cars that I have heard, the trunk really takes away from the sound quality that the sub produces. I plan on running a 12" JL 12w6v2 and feeding it with about 4-500w rms. So I guess I shouldnt hae any issues.
