I agree with the last poster...there comes a point of diminishing returns. I think that point is about 1500.00 for me, more like 2500.00 for most people. 2500 will get you top quality stuff at every component. 1500 for me because I refuse to pay more than 175-200 per sub when the best quality sub on the market is about 179.00.

Plus, I would do stuff like build my own crosovers and such which would allow a pretty cheap system.
