    Dynamat Installation by "Pros"

    Has anyone every subbed out (went to a shop!) for a full Dynamat install? 2014 Hatch. Want it more quiet. I just know the WRX has very little sound deadening. I have actually installed Dynamat and other sound insulation before and did a nice silence job on my old Volvo 1985 245Ti and before that a 1971 Datsun 510. But those cars I wasn't worried about taking door panels off and such. Plus now I just don't have any time. (I worked 62 hours at my regular job this week and didn't count the hours at my two companies that I run)

    Where the heck do I start? Car Audio shop? How much do they charge? Will they F up my car? Obviously a complete newbie - any helps from CLUBWRX would be sweet! (no I'm not asking on the BIG NA.... site)

    Thanks!

    It's not just mat that's important on these cars...

    Good deadening writeup:

    It's one about an older model, and not a hatch, but it gives you some info

    Found a really GREAT local guy through a local gun forum Chris at Home . Great little series of shops. He took the entire day dedicated to my car and used quite a bit of Accumat (effective as Dynamat, easy to use and stick better). I would have taken a LOT longer and I would have broken stuff. I watched him work for awhile at the beginning and end. Well worth it, IMHO.

    The result. Simply, unbelievably amazing. I can get all into the boost getting on the freeway and I don't need to turn the radio up. Simply quiet.

    How much weight do you think this process added to your car? I'm toying with the idea for when I overhaul my stereo, but I'm not sure If I want the excess weight.

    I've been considering doing this to the trunk and back seat area of my 2010 sedan. I love my exhaust, don't want to change it. Just would like to reduce the drone a little for long driving intervals.

    I read that dynamat combined with something like Raatmat?? Was better at deadening the sound.

    The WRX has so little, just adding some to the larger panels will help.

    What you want more than matting material is mass loaded vinyl.. but you have to isolate it from the other panels of the car with some closed cell foam.

    Good MLV is about 1lb per sqft... so you can figure out the weight from that alone.
