I'm in the middle of upgrading my car stereo, including replacing the front components with Diamond Audio M561s. While I have the doors apart, I wanted to work on sound deadening the doors. (The car is already relatively quiet, but more is better...or maybe less is more...)
I had been using p/n 9709T18 from McMaster-Carr (
www.mcmaster.com). This is a heavy (0.7 lbs/sq ft), cheap self-adhesive sheet of asphalt-based damping mastic. I got one door finished before I ran out, now they have a 19 day backorder, so I need something quick!
I am also considering adding some material under the carpet while I have the car apart. I definitely want to add some material to the trunk as well.
Q: Should I rip out what I have done on the driver's door so that both doors will use the same material?
Q: What material should I use in the doors? The vinyl nitrile foam? If so, what thickness is preferred or at least adequate (I'm on a budget)?
Q: Do I use the same stuff in the trunk as the doors?
Q: Use mass loaded vinyl for the floor? If so, do I need the foam backing? Does the whole surface area of the floor need to be covered?
Q: Do you sell your adhesive in smaller quantities, or is there an alternative? I'm guessing I don't need a quart for this application.
Q: Do you sell (or can you recommend) a spray-on deadener similar to Dynashield for hard to reach areas?
Thanks!
