I just wanted to get your thoughts. This is for a coupe, by the way - After reading everyone's posts, I went ahead and went to home depot. A worker there said what might work better than fiberglass insulation is the stuff from a can ... "Great Stuff" is what it is called. I had enough to fill 3/4ths of the left and right compartments, and just stuffed blankets and sheets in the middle section.
After driving, I still didn't notice any difference (*maybe* a very slight difference ... maybe). Did I just mess up? Should I go for the cone foam instead? Is it because I have a coupe? I'd love to hear what those of you having done it have to say. Thanks!
Yep, you goofed up. BTW, the guy was kidding about filling the compartments with foam! The fiberglass dissapates and absorbs soundwaves. SOLID FOAM does not ! AND you need to do all 3 compartments with fiberglass or lightweight foam sound insulation.

I'm going to try something like that (not Great Stuff, he's got to be kidding about that!!!) in our C4 convert. with muffler eliminators. I like the full sound at WOT, just don't like the resonance and constant drone when cruising at 80. Great thread.
I took the heavy rubber mat that you buy for pickup truck beds and cut it down to fit the back area of the C-5,it makes a huge difference and fits under the carpet well.
