sounds to me like you want to buy some subs put them to a huge amp and make alot of noise. fuck that! there are to many aspects of a good sounding system to do things like that, and if it gets done its sounds so fucking ghetto. just get yourself 2 12w6's and a pure 1000 watt amp and then some quality mids and highs with a nice power class 4 channel amp and then play the all important part of making it sound even. of course you will need things like bass blockers and a cap here and there and maybe a cross over or 2 but when its all done you will be mega haappy.
