well my setup now with 6x9 in the rear i have a low pass electronic filter set at 5000 hz, and that gives the best sound. I heard tweets only play over 10,000hz, so i figured i would do without them. But with my current stock speakers it probably sounds crappy because I dont have tweets?

I guess its a matter of taste but Its just so hard to tell unless u already have it installed and usaully by then its too late. Does anyone else have anythign that might help me?
