David:

I have a diagram of the location of the compnents on the stock C system for 98, and they show an amp. I have been told by many that just changing the front speakers will go a long way towards improving things, and I am about to do that (Installing Koni adjustable Sport shocks first! ). If you want a copy of the diagram or want to go over the speaker arrangements I am planning, drop me an email.
