Cheap, easy, effective soundproofing (with picture)
I have to give credit to Choreo's post about soundproofing, when he said that carrying a roll of fiberglass wall insulation home from the store reduced his car's noise, I got thinking.
I cut 3 pieces of 3 1/2 inch thick fiberglass batt insulations to fit in the rear three compartments. I used paper faced with paper up. 6 inch insulation would fit, but I used what I had on-hand.
The results in cutting noise are AMAZING !
This is probably the best and cheapest mod I have done to my car. Those wells must be acting as "speaker enclosures" and amplifying the sounds.
Z06's who don't even have lids on these wells, do this and put wood or cardboard (carpet covered) over them and you will be amazed.

The tubs in the back are just perfect for resonating, and picking up a ton of road noise. Especially considering their relation to the wheels and exhaust.
What he did was stuff the rear tubs with insulation. Cheap and effective way to do it, though you lose storage space.
If you were to take about 1" thick of foam, and attach it to the bottoms of the storage lids, you could get much the same effect.

It looks like he hasn't seen your Frost King write-up. If it's been a while since it was posted you might want to re-post it so many of the newbies can learn about it.
I did the Frost King mod on my 02 vert mn-6 over a year ago and it really made a big difference.

Does sound like a nice, cheap way to cut down on noise. Thanks for the idea.

Does any of this fiber glass insulation come in contact with water... I had a friend of mine ,,,,,back in the 80's,, he put that insulation in his door panels, trunk area,, and where ever he could.. Well the insulation in the doors sucked up so much water it destroyed the doors.. You have to careful what you're covering up when you soundproof, you could end up doing more harm than good..

True, just adding something like a Lloyds Carpeted - Heavy Foam Cargo Mat will pretty much take care of the sound coming up through the rear compartments - it is very similar to adding DynoPad only more versitile and looks good. This was my first sound deadening step 6 years ago and it drops the noise level in the rear significantly.

None of the fiberglass contacts water, this is INSIDE your rear compartments.
I already added a Lloyds full rear carpet, it may have cut down some noise, but not anything like the fiberglass batts did.
Still waiting for my picture to be processed.
