Dynamat 10415 Xtreme Speaker Kit 2 Sheets

Installation was very easy, just peel and stick. I could definitely see an improvement in bass, sound quality, and I also noticed that the rattles around the speakers have disappeared. Unfortunately there was still a lot of rattling throughout the door, and distortion seemed to be there on high volumes still on my Alpine speakers.

Overall, this was a decent buy. It may be difficult to install for those who have no idea how to take out the door panel. The price is quite nice though, for those who are iffy on the whole Dynamat scheme.

Dynamat worked for me. My rear speakers rattled the trunk of my Millenia when I installed my pioneer 6 X 9's. this weekend I removed them and put some of this around the speaker opening and the rattling is gone. also the distortion at higher volumes is gone and the bass sounds better. I also purchased some pioneer 6X8's her on amazon for my front doors and added the dynamat to them also. They too sound great with good sound and bass.

I will say that installing this stuff in the rear was a bit more work than I envisioned but it was well worth it. I did not by a roller, I just smoothed it down with my hand and the back of a srewdriver. What I did buy to cut it was Black & Decker SZ360 3.6-Volt Ni-Cad Cordless Power Scissors from Marshalls. They were $12 and worked perfectly. I wore gloves when I tried to lay the dynamite down but the backing kept getting stuck to my gloves so I just installed it without gloves. That worked better for me and did not get my hands all sticky like some other people here.

I would recommend. Great price too. $25 for 4 sheets here and $25 for 2 sheets at circuit city.

I started with the speaker packs. I saw very little result. Then dynamat said, well you really need to do the whole door, so I did. $400 later, I still have as much road noise as before and I covered my entire door frame on all 4 doors.

Don't buy in to the hype.

Thought that this would be a miracle worker for taking the vibrations from my car away. After several applications, (One over another) I realized, the vibrations just are not going away. Pretty disapointing for the money spent..............

this stuff really works!! gets rid of that annoying rattle that can disturd your listening pleasure
