How much sound deadening material?

Hey Big! Been reading your posts for a couple of months before my account got approved. Love the massive treasure trove of knowledge you have provided to the forums.

I'm not looking to eliminate road noise, but I do want to try and get maximum reduction of future bass rattle once I put one or two 10's in the back. I place a premium on SQ, so anything that helps that is what I am interested in.

Edit - Looking at the second skin stuff, and that might be the way to go it seems. About double the price, but if it works as well as it seems to that would be worth the investment.

Thank you Knight!, Always enjoy sharing knowledge.

So I can see maybe needing probably 20 sq ft with a few sheets left over. This should do your doors and your trunk lid and your trunk depending on how crazy you go on the doors. Make sure to roll up some of the rubber from a sheet and apply some around the clip openings for your panels to help with vibration as well.

Zbeach - can you throw up a link? I can't find anything on Amazon.

I went full out tweaking on getting rid of rattles last year around this time. I have zero rattles in my car unless I really crank up my subs. I used Noico as it works very well and was cheaper than other brands. However, I think using a sound deadener is really only the first step.

I remember there being a plastic piece or wire on the passenger side near the rear wheel well that was causing a loud annoying rattle. I used some speaker gasket tape and wrapped it, which eliminated that issue. It is very annoying to actually get some foam back there though. It took me about 20 minutes to get it to sit right.

I also lined all the outside edges of my panels (where the panel meets the metal) with speaker gasket tape (i.e. closed cell foam). Like bigaudiofanat mentioned, throwing some rubber or foam around the clips also helps. To be more clear, I took off all the clips, wrapped them in foam, and shoved them back into the panel.

It's very difficult to eliminate all the rattles in the doors. I have about 50 sq ft (possibly more) in just my doors. I think each car will be different but another possible tip that may help is to loosen up your door handles while you have your panels off, and shove some closed cell foam underneath the door handle where it meets the metal. I was also getting a lot of rattles from that section when the woofers hit.
