That was the preclay an I only worked on the center portion yesterday. It did help a little bit but not enough for me to sit there for hours. As for the head unit I finaly spent the time to get rid of this high pitch whine that you could even hear outside of the car. Turns out the ground wire coming from the stereo was connected directly to some of the speakers. I dont know I'm just as confused as you why it was like that to begin with. I know I need a new stereo because the current one doesnt fit and I didnt find a mount for it, but I'm debating on rewiring and replacing the speakers.
