hey sport,
have you noticed the drift in the bass level at different volumes? i put one of my alpines in my wifes 99 yuk to drive two infinti 12s and noticed that at low volume levels the bass is way into overkill, but when you get it up to what should be a perfect level, the bass just gets weak. i've got chokes (47mfd front and 99mfd rear) on the factory speakers to keep from distorting them when i get to borrow the family wagon, but that just seems to make the all around sound seem like a poorly adjusted eq. i've tried all the factory presets for jazz, pop, etc, they just don't sound right. i've set up $500 systems to sound killer, and i have also seen customers spend over $5k and their cars come out of the shop sounding like crap, so i know that proper tuning is the key. i was just wondering if you had noticed the same thing, and what you make of it.
