## Description

Product description

Review: Worth the money. - I installed a basser box 10 inch in my Audi s5 sportback in the right side compartment. I had it for a months but just added this sound deadening behind it. It made such a huge difference. The rattle from the metal panels are gone and all the sound goes into the cabin instead of out of the side of the car. Pretty easy install and I didn’t even use a roller tool.
Review: Amazed at the effectiveness of this product! - I have been an car audio enthusiast for many years, but had previously not used this product. I recently upgraded the rear factory speakers in my 2013 Honda Accord coupe with a pair of JL Audio 6.5" coax speakers and decided to use Dynamat with the install. My EX-L V6 Accord came with 2 speakers and a sub mounted on the rear deck above the trunk. The metal mounting surface has multiple small holes in various areas that prevented the trunk area from being a tightly sealed enclosure for the 3 speakers. I installed the new JL speakers in place of the factory singe cone units and tested their performance for a bit before applying the Dynamat and reassembling the rear trim onto the deck. The new speakers were a big improvement, however after installing the Dynamat and closing the trim up the bass response from the rear speakers and sub was amazing! It sounded like I had added an aftermarket amp to the sub. The rear deck has a rather irregular surface and required cutting quite a few separate pieces to be installed sort of like a jigsaw puzzle. My son and I took our time and were able to completely cover about 90% of the area using just a little over half of the 18" x 32" sheet. The acoustic improvement was so impressive, I will now likely plan to address the inside of the trunk lid and the inside of the door panels. I couldn't recommend this more highly!

## Questions & Answers

**Q: Can this be used on a engine cover/dog house on a inboard outboard boat**
A: I can't speak for your I/O boat but I used it in my van's engine cover which gets really hot and have had no problem what so ever.  Good luck.

**Q: Is there enough material to cover two doors**
A: Not unless you have really small doors. The better way to do it is with the "door kit". It consists of 4pcs of 12"x36" and is made for 2 doors. What ever you don't use on the inner door skin you should use on the outer door skin. And don't forget directly behind the speaker. I used 36 sq ft on a 04 f150 with the doors and rear wall including back floor where the dual subs are.

**Q: how many sheet would you use for 4 car speaker?**
A: Hi Thank you for the question, and it really depends on how much you want to spend.For example, "I" would use just one of these 32x18 sheets for one door. Applying to the outer door inner panel as well as the door panel for the speaker.This way you will not loose your music to the car next to you, or entertaining everybody you pass.You may look into getting 4 boxes of these and do that, or you can get (2) two door speaker kits (12X12).I would recommend the full coverage for medium to high powered audio systems. Especially if your vehicle is Honda , Toyota, or where the sheet metal is super thin.Thank you for choosing the Wires Zone.

**Q: How does it hold up when it gets wet regularly? My jeep leaks...**
A: Water does not effect dynamat at all. Once installed it sticks very well to the metal surface of your vehicle. Just make sure the edges are pressed down well so water can’t seep under it and start the rusting process on your Jeep. Clean the surface well before putting the Dynamat down so it sticks.

Excellent product that meets the description very well. It is firmly adhesive and stays in place after it is applied and it can be rolled out flat very quickly making a nice smooth surface.
