JBL Stage 800BA

This multi layer sound deadening is great. In the past I have used multiple layers to get the best results for my vans and this stuff combines them to cut install time in half. Noise inside my camper van is significantly cut making long drives much more pleasant. The sheet size is perfect to cover large areas. My only complaint is that some of the foam layer tore while rolling making it hard to get super clean look. But since most areas get hidden this is not a problem

Using this product in the door areas for mid bass improvement. I used 2 of the SDBBP40 (without the third layer of foam) to cover the whole inside of the vehicle. When I ran out of material and needed a bit more for the doors, I was thrilled to Find NVX added a dampening material with the foam backing. This is a NVX install all the way: speakers, amps, cables...

Decided to try this over the regular sound dampener due to the foam layer. So far it seems to be working and has minimized the rattling from my bass speaker in the trunk.

I'm not sure how there could be a complaint here. I was pleased with the quantity of material I received given the price I paid. It's extremely adhesive material and very easy to roll down. It's malleable, yet heavy. It worked very well for the trunk and rear doors, and I may need a smaller quantity to cover the front doors, but that's still a full car under $100. 5 stars.

It work so good my trunk stop from shaking, and it was a great price
