The stock stereo routes freq's to the door speakers that they cannot handle. A low pass filter will let them be mid-range speakers, and let you boost the bass to the subwoofers without that annoying distortion.
Check out the "best stereo bang for the buck" thread.
It's a simple mod and really cleans up the sound.
I am all for doing the capacitor mod, but I have only one concern. I really like a lot of bass in my music such as the thump you get from rap. What I've noticed is that most of that comes from the door speakers. Will you still get the same thump and bass levels, but just from the rear speakers?
