So I gots me one. 160k miles. Previous owner was a neat freak and and a bass head.
I was out in the parking lot messing with the audio when a guy driving by complimented the undistorted thump. I asked where he was when he heard it, thinking he was in the parking lot. He said he was on the third floor. Great, now everybody knows. I moved the car to the other side of the building where they don't know I'm an @sshole.
Money For Nothing, it turns out, can make the back of your head feel like a phone set to vibrate.
I'm in the process of unbridging the amps. The feed for the 4 door speakers was split from the rear speaker feed but the right rear fed the front left and the left rear fed the right front. I spent a couple of days trying to balance and fade that before looking at the wiring. Good times. It actually took me a long time (over a day) to even understand what had been done with the wiring. I had confused right and left for pos and neg in my analysis which left me thinking 'car fire'.
Uhmmm ... then I duct taped the air box where some previous wiring melted a 3/4" diameter hole ... maybe a little bigger: oblong so it's hard to say. Not that big.
