(2) Polk Audio MM842DVC 8” Dual 4-Ohm Car Audio Subwoofers Subs+Sound Damping

Best in sound damping

I've have bought couple of stinger sound damping materials an they are great to use did a whole car once an now working on a SUV definetly worth buying little cheaper then others but worth your buck would like to buy more to finish off bottom floor then the foam next but it's worth it I recommend to others

Best Value for the Money

Way cheaper than Dynamat and just as good, if not better quality. Def. recommend this product and SonicElectronix for great deals.

Stinger rocks!

The stinger bulk pack is a great deal on Sonic! The stinger expert roadkill does everything as advertised. It's very pliable...sticks without prep and makes your car cool and quiet and is easy to install! Great product and every bit as good as dynamat and a better bang for the buck!! Go buy some now if want a rattle free car for your booming system!!

Heavy duty

The stinger roadkill expert series really works. If you need proof just properly install a piece in a location and try knocking on the installed area as opposed to a bare metal area. It will knock surprisingly quiet with the roadkill and loudly without. I put some behind the front speakers, around the speaker where an area was available, in the trunk, and behind the trunk lid. That along with listening to a bassy song and securing the panels like the rear deck with some automotive glue and double sided foam tape really made a huge difference in sound quality. It also makes the ride more quiet when the stereo is off so you can't lose. Check out some videos on YouTube if you've never attempted this. A set of gloves may save you some unwanted cuts.

great stuff!!!

better than dynamat and some other stuff ...stinger roadkill expert is great covers easy sticks well and does its job

Excellent Product

Product was used as an insulator as well as a sound deadener. It was very easy to use and cut my road noise by 50% or more.

Works better than intended

Did my entire truck with this and another kit, bass stays inside, SPL increases as well as sound clarity, it is much cooler and sounds better. Gonna win this years SPL competition!!

Stinger RKX36B

This product works wonderfully! To owners of larger vehicles(mine is a '94 Grand Marquis): this 36 sq ft JUST covers the entire trunk, including trunk lid ;) :)

Stinger!!!!!!

Great stuff! Works as intended! Can be a pain to install but i found it best to lay it in the sun and get it warm before installing. A little dissapointed with the shipping though. Took Sonic over a week to get it shipped.

Simply Amazing!!

I strongly recommend this product! I have it only installed at the moment for my stock Bose system in the doors, and it makes a huge difference. The clarity of the overall sound and even the bass is amazing! I installed it all myself and it was very easy to do so. I do suggest that you get a roller to help with Install. It made it so much easier and you can tell the difference with the adhesive. The price you can not go wrong. I am going to have more installed in a week when I put my subs in.
