JBL P660C + Sound Dampening

A lot of materual

Ordered this for my F Super Cab. I just wanted some material to apply to the inside of the door skins. It is a lot more material than I needed. Ford already has a small amount of sound dampening material. It did quiet the interior as expected. Great product. Came with no instructions. I just used some alcohol to clean the surface first.

love it!!!

Love this product. Great price and easy to work with.

Great!

put on my trunk to stop rattles. worked great, doesnt sound like a tin can from outside. thick stuff definitely a good deal. as good, if not better, as the bigger sound deadener brands but at a lower price. i highly recomend

Impressive product

This is a very stout, impressive product. It feels thicker than the famous competition and there is no smell to it. The sheets you get are sort of a long/narrow size, so they are great for running vertically up the doors and on the outer door skin. You'll definitely want a source of heat when working with these and really, there isn't a better value for the kind of product you are getting here.

NVX 12ft.

This is great material for a great price. Ive bought multiple nvx dampening products and have been pleased with everyone. This this easily applied with a nix roller and contains the perfect amount plus some to use on your doors.

Seems fine

Used on rear door skins. No smell, easy to manipulate.

Great for Rattles

Installed this stuff in my front doors and enough for the speaker area in the rear doors. It only slightly reduced the road noise in my car, but tightened up the bass and reduce rattles by a huge degree. This stuff is easy to install and can often be bought on sale.

Good product

Easy to work with and in my opinion it performs better than dynamat!

Decent Dampening

I have had this for almost three months on my trunk lid and it has made a big difference. The rattling is not as bad as it used to be and it made a difference inside the car.

DON'T buy this if you live in arizona because the heat is too much for it.

awesome

Best 99 bucks i ever spent, loud clear and stage perfectly, way to go jbl. I've been in car audio for over 2 decades, almost owned everything, diamond rockford focal, these jbl's get the job done...very pleased.
