SuperStock Posted May 27, 2013 Report Share Posted May 27, 2013 Has anyone used dynamat under the bed of the truck to help reduce drone? Quote Link to comment Share on other sites More sharing options...
AdamVRed03 Posted May 27, 2013 Report Share Posted May 27, 2013 I don't know how that would hold up under the bed facing the ground due to the elements ? Why don't you just put it in the cab for noise? Quote Link to comment Share on other sites More sharing options...
ssfast Posted May 28, 2013 Report Share Posted May 28, 2013 I dont think it will hold up in the elements like said above! Put a thick layer of Under coat and put dynomat in the cab! Quote Link to comment Share on other sites More sharing options...
SuperStock Posted May 28, 2013 Author Report Share Posted May 28, 2013 I will have to look into the undercoat. I though the dynamat would hold up because I know you can use it under your hood, but I guess the elements of being under the bed is a different story.

kissfans03ss Posted May 28, 2013 Report Share Posted May 28, 2013 Dynamat is usually used inside the cab for noise/heat deadening. Sent from my DROID BIONIC using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
Sirbutler Posted May 28, 2013 Report Share Posted May 28, 2013 Dynomat is designed to be inside a vehicle. If you place it under your bed it would hold a lot of moisture and debris against the bed and promote premature rusting which would be a bad thing. I would just put it in your cab or check into an exhaust blanket for the muffler. Quote Link to comment Share on other sites More sharing options...
Wrebitup Posted February 9, 2014 Report Share Posted February 9, 2014 Has anyone done back wall of cab in dyna mat and got drone down to reasonable levels or is cab and floorboard all been done at once .I ask because I had a couple fishing rods sitting behind head rests during a camping trip and they buzzed like crazy at same rpm as the drone .I am thinking of double layer on back of cab to stop vibration .Interestingly my two 10"subs also make back of cab buzz I turned amp down to stop this ,everything appears to be tight ???

Bigtoyz97 Posted February 10, 2014 Report Share Posted February 10, 2014 There are different types that you can use, probably want to use something like the dynaliner vs the thin stuff. But you can put multi layers of the thinner stuff....is what we did in areas of my car I had for car audio competition's. Quote Link to comment Share on other sites More sharing options...
cb2big4u Posted February 10, 2014 Report Share Posted February 10, 2014 I had to deaden my cab. Roof being the most noisy. Back wall just got done and helped tremendously. Floor is next. Just an fyi for everyone that is going to look at this. Do research on your deadening. Dynamat works but it is retardedly overpriced. I used murdermat on my truck. Same shit, half the price. There is also cheap crap like rattle trap deadening. Tossing it out there, don't want any of you spending more than what is necessary. Sent using Tapatalk.

Akslowroller Posted February 10, 2014 Report Share Posted February 10, 2014 I also went a different rout and used hushmat. Great product for a lot less Quote Link to comment Share on other sites More sharing options...
