[QUOTE="soydeedo, post: 2919469, member: 574991"] closed cell foam could be a decent comprimise between no deadening and heavy deadening since you'll at least get a little of the sound absorption qualities. also liquid deadening might be a little more lightweight than regular mats. but yeah a big part of deadening is to add weight to thin sheet metal to reduce vibrations, but maybe if you reduce the acoustic energy the sheet metal receives [via overkill or ensolite] you can help in that regard without adding as much weight. shrug.
