Sound Insulation

[Joenavy85]

Has anybody used sound insulation on their roof? I had to drive through a downpour yesterday and the noise was almost deafening (had the Ipod hooked up and the head unit on 35 and could barely hear the music). I was thinking that adhesive backed rubber sheet, maybe 1/8"(3mm) thick might dampen the sound by a fair amount. Anybody have any suggestions?

It's not a big deal while parked, but I prefer not to drive with earplugs in. Sometimes it's nice to talk to the occasional passenger and that doesn't work well with earplugs

what is dynamat like? isn't it for deadening/insulation?

Yes that is what dynamat is for but check out Elemental Designs: Car Stereo, Home Speakers, Electronics . They have a few different solutions the cTherm blocks more of the upper frequencies and helps insulate.

Look for "Fatmat" on eBay, it's a dynamat knock off that performs just as good, and is much cheaper.
