sound deadening review and stickied?

Chuck33079 · 07-14-2013, 09:20 AM

One layer of Raamat in the hatch, with a layer of closed cell foam over it. It cut down on the road noise, and the bass does sound clearer. No before or after db readings, though. I'll do the doors, floor and headliner when it's time to redo the stereo. I'm only opening the doors up once. I'm trying to avoid creating rattles.

stay away from anything tar based, other than that second skin is my fav stuff.

How much do I need just for the two doors? any forum member discount?

This stuff sounds lightyears ahead of everything else being multi layered with different layer types unlike everything else out there!

changed my mind and will go with GT Onyx. I'm going to support those that support our community.

If you sent us a PM, sorry for the delay in responding. I've been out of the office.

NP, I just sent msg to GTmat on how to buy. My speaker/woofer just came so I'm getting ready to do everything at once. I even DL a simple DB meter for my phone to record before and after.

Hey Markesc,
I no longer work for the company. If you give them a call and offer to purchase over the phone, they used to give 15% off but I'm not sure if that's the case anymore. Less would be more so I'd say maybe 2 squares for each door, cut and strategically placed.

Just ordered some, they're doing 15% off right now. Got 15 sq feet, so should be able to do the doors and rear hatch/trunk area with some spares for future use.

I think this plus those lanzars and callin it a day. Would love to upgrade the tweeters but I'm lost on what will/won't fit/and is not harsh sounding but will work with the low powered stock deck.

For future reference, Noico is relatively cheap and works well. No smell at all. Definitely beats paying for overpriced deadener like Dynamat.

I've tried second skin in the past, which did well, but layering the luxury liner pro ontop of it just didn't make much of a difference to warrant the additional weight penalty in an 07 wrx.

My hope this time is that the multi layered gt mat stuff will do a little better, but I'm going for a single layer and calling it a day because of the weight penalty which I plan to offset by removing the spare? I had a lexus sc300 and when I removed the spare on that one, it created more noise, so it stayed.

Agree 100% I did doors with Dynamat extreme, then tried Noico for the hatch area. Noico cost was so much more reasonable, and quality was at least as good.

Anyone looking for info on this a great resource is https://www.sounddeadenershowdown.com/

He sells his own products too... but the information, guides, etc on there are beyond useful. There is more to these upgrades than just loading a ton of mass to the body... reading up will help you decide between products which, on the surface, all appear to be pretty much the same thing.
