Re: Sound proofing a C4 (MEATHOUSE)
One of the main functions is to deaden a panel from the drum effect and cancel this making it sonically dead
"drum effect" ... that's the best description I've seen describing the noise generation. Exactly describes what is happening.
What material did you end up using?

Re: Sound proofing a C4 (Mike Mercury)
I am going to finish the installation of the Frost King sound proofing this weekend weather permitting. I am very happy so far with the results from the passenger side install I've done so far. Thanks for the description kudos. I worked as an installer for 3+ years and have built home speakers and done "friend" installs for the past 15 years. I'm hoping the FK will work well enough to kill my exhaust resonance and quiet the flywheel rattle. Seems to be doing the trick on the one side but until I get it all in I won't know for sure. Since it is relatively easily reversable,cheap and lighter than other sound proofing, I figured I'd give it a go. Thanks for the idea Mercury Mike!

Thanks for the heads up Mike. I still need to do the rest of my car. Even if it doesnt work as well as some of the more expensive stuff, the price was definitely right!

Re: Sound proofing a C4 (VetteNoob)
Mike, I'm very eager to hear your result with the Frost King after you complete your job. I looked for it at a local Lowes, they told me only the superstores carry the product, nearest store 35 miles. I will wait to hear your results before I take the trip.

Re: Sound proofing a C4 (92dreamin)
I did the rear this weekend. This leaves the tranny tunnel top and the driver's side to do. Wish I had a garage with AC to work in. Working in the lot with the temp reaching 100 degrees just slows me down to much. Anyway, the rear was finished and the noise dropped dramatically. Obviously I have a vert and I also have a large sub box filling the cargo area. So the proofing went in a u-shape over both tire wells and along the back and took about an hour. This quieted the exhaust note from the PE to about 2/3s the amount it was louder than the stock exhaust. I can talk again to my passengers without shouting under acceleration. Also, the noise level at cruise is back to stock. Very nice. I figure with the rest done it should sound like I'm at the stock noise level inside with a power effects exhaust, aluminum flywheel, and stage three clutch.

Re: Sound proofing a C4 (Mike Mercury)
Sorry Mike still too danged hot for me to sit in the back of the vette in my apt complex parking lot in 95+* Texas heat :crazy: Ill get to it in a few weeks once the weather has cooled down or when I visit the parents in Houston. Though I may feel kinda bad for being in the garage the whole time when Im supposed to be visiting them :lol:

Re: Sound proofing a C4 (VetteNoob)
Well I started mine yesterday. The frost knik stuff is pretty easy to work with. The hard part is getting everything to lin up with the extra layers in there. I double coated the bottom pan to further kill the drum effect. I might be over killing.
I can't wait to hear it all done, or that is not hear it. Took 2 hours to do the pass side door and pass side cockpit.

Re: Sound proofing a C4 (Glasman66)
I didn't take any. Looks like the brown bread photos Nomad had and Mercury Mikes Z06. Just think of putting double sided tape with foil backing all over. I removed screws for a few wire harnesses and mounted the wires back on top of the insulation. Pretty easy job. Taking apart the interior was the tougher part. I'll try to take some pics when I do the front. I don't have a digital camera yet so I'll have to scan some at work.

Re: Sound proofing a C4
Well, I had to pull my pass. door apart this weekend as the window stopped working. Got to the harness and I think it was just corrosion of the contacts. Cleaned 'em and reseated it and seems to be working. Anyway, since the door was apart, I went and bought a roll of the Frost King stuff and did the outer door panel (inside of the door behind the window). Pretty easy to work with. I plan on doing the rest here and there when I have time.
Curious about 2 things for the other guys who are pursuing this. Were you able to fit any of the material on the inside of the door under the trim cover or did you place it all inside the door (behind the window)? Also, are you using multiple layers or does one seem to be sufficient?

Re: Sound proofing a C4 (VetteNoob)
I called all the Home Depots in Oklahoma City and they didn't even have the SKU mentioned above and don't show Frost King as a vendor. They said it might be a regional (cold north maybe?). Called Lowe's and finally found a guy that had a clue and said they had the tape in plumbing. Went down there and had to be a little persistent, but finally got a dept manager who knew what it was and where it was located. In this store it was in the far back near the water heaters :confused:
Anyway to make it easy for someone else the SKU at Lowe's is 28929.
Already had both doors stripped down replacing the window motors. Have removed all the door latch and handle pieces for cleaning and relube. Thanks to this post I will cover the metal center panels with the Frost King.
Have all my new window seals and new door panels. Hopefully when I put them on I won't be seeing the inside of the door for a loooong time. :yesnod:

Re: Sound proofing a C4
This is a great topic and wanted to suggest a few things.
If youre doing the car and have extra pieces left over,try installing some inside of the roof where the Halo panels are above the seats.I have them off and can see the bare skeleton of the frame work and see where GM stuck a few small sticky pieces of noise reduction pads but theyre marginal.May cut down some noise by insulating in there as well.
For the spray foam route,if you jack the car up and remove the back splash shields from there,you can see the inside of the back quarters and crevices behind the door jamb frame etc.May be good areas to spray in there to help lower tire/road noise.
You may even be able to use some dynamats or equivalent in these areas in small sections(may need to find a more permanent way to attach them) and then the splash sheild will cover them up once reinstalled.
These are just ideas Ive had since I had these pieces off the car for some time while doing some work here and there and noticed these areas.
Either way,Good luck and keep us all posted.I may take on this project myself when the weather cools down a bit more next month.
