how much???

how much would i need to sound deaden my whole single cab tacoma???
i seen this 8-24x27 sheets of scosche for 300

 

You mean vibration dampening? Cause that is different than sound deadening. About 6-8 sq feet per front door (12-16 total inside and out, 8 sq feet for the rear wall, and around 8 square feet for the roof. So 32 square feet of vibration dampener. You may have a little left over for misc small spots on the floor and kicks... truck has tons of floor deadening from factory. Thats for a deadener that requires more coverage due to thinness like Dynamat, Fatmat, Soche Accumat, or whatever. That Sosche Accumat is horribly overpriced for what you get. I dont know why you are obsessed with very particular off brands. Do you have a shop that sells it or are you reading about it somewhere?

Thats just vibration dampener... it wont block external sound well. That requires closed cell foam and mass loaded vinyl... which will be about twice as expensive as the vibration dampener.

yes a shop carries it.Also my main goal is to get rid of vibration from the sub and to get rid of the outside sound in the back of the single cab.... mainly around the vents.... i was reading you cant seal them up or can you???? if not then i guess would it be best to epoxy the plastic vent to the cab to stop the vibration from the vents vibrating and.....
