DIY: Sound Deadening The Hatch

flashburn · 09-06-2010, 04:39 PM

Yep, totally worth it, and not really that much work compared to the amount of use I get out of the car.

Did you finish your doors?

Is it a "night and day" difference in road noise reduction?

flashburn · 09-06-2010, 05:42 PM

Nope, haven't done the doors yet. I probably will once it cools off.

370z2k10 · 09-06-2010, 08:04 PM

Where are you...Orlando area?

flashburn · 09-06-2010, 08:28 PM

Yeah, I work in Orlando, commute from Deltona.

I have to echo flashburn, totally worth it. I did my Z after reading this write up. I didn't order enough damplifier in my first order and only got about half the hatch done, and in my second order I got the damplifier pro, which I think made a difference over the regular damplifier. My car sounds 100% better and is now tolerable. Not perfect, but much much better. I did not do doors, and don't think I will at this point.

Did you use the luxury liner pro on top of the damplifier?

tsolin01 · 09-08-2010, 11:43 AM

It definitely helps with the road noise but watch out if you're using Luxury Liner Pro as it's very thick. The back panels don't quite fit right anymore and it's hard to line up those plastic tabs back in the holes. Also I have the bose system and I couldn't get the sub to screw back into place because the LLP was too thick. It doesn't rattle around or anything but I figure I need to secure it better eventually.

I got mine to a decent fit but I'll need to go back and really look at how things fit and maybe redo where I placed the LLP. I would recommend at most 2 sheets of LLP for the hatch, but probably 1 would do the job without bulking everything up.

flashburn · 09-08-2010, 11:50 AM

Yep, I mention it in the guide I believe, to be careful with where you are putting LLP. Some of those panels are extremely snug as it is, so in some spots you can't add any LLP. From what I've seen myself and read, the doors are an even bigger problem. I probably won't do LLP in the doors, just SPL Tiles.

With thid mod, the car will be extremely better when it is time for you to replace those stock tires (Bridgestone RE050A) with the Continental ExtremeContact DW. The Continental tires are much quieter, last twice as long, and have a very high performance rating.

So how much of the damplifier pro is needed for the hatch? I'm thinking I'll do this mod soon.

I am thinking of doing my hatch and I was trying to figure that out too. I found an old link to the SPL tiles, and appears that they are 6" x 10". The pics in the DIY (tiles next to spray can and scissors) seem to support that. DIY says about 25 of the SPL tiles are enough. That's works out to 10.4 sq ft. The second skin site has a 10 sq ft pack for $34.... getting time to do the install is the real problem for me.

flashburn · 09-15-2010, 06:13 PM

Yeah, I think the 10 sq ft pack should be good for the trunk area.

FaZt 1 · 09-16-2010, 02:50 PM

Actually, I think I used two packs of Damplifier (acutally one of Damplifier and one of Damplifier pro). Used all of it and probably could have used a couple more sheets. I think each pack was 10 ft.

flashburn · 09-16-2010, 04:53 PM

Wow, did you do multiple layers or something? My calculations were for a single layer, as I didn't want to add too much weight to my car.
