[QUOTE="cleanerupper, post: 2095067, member: 569517"] Is your speaker sealed into your door correctly? If not, do that. Also I would get rid of the EQ at 125Hz and 200Hz, and widen the Q of the boost at 80Hz a little bit. Your amp might be either clipping from too much boost and/or pumping too broad of a frequency boost into the speakers (80-200Hz), causing the distortion effect at higher volumes. You have to be careful boosting midrange sounds. You say your components are high passed at 100Hz@6db/oct, so lower frequencies shouldn't be the problem causing distortion. I don't know what BBE or Comp is because I don't know Pioneer decks, but it sounds like they may be audio enhancement features, which also apply their own bass boost. Try lowering the setting to 1 or turning it off all together. If this gets rid of too much midbass, you can raise up equalizer settings to compensate. Still, try to use only 1 band of EQ in the 80-200Hz range, not 3, since that will introduce distortion earlier. Instead, try centering the boost at 100Hz and widening the Q a bit. [/QUOTE]
