I have alittle dynamat left over from a previous project. Where would my left over pieces do the best to eliminate road noise? I figure the wheel wells for sure. But where else? I have enough for a single layer on the wheel wells and maybe a single layeron a door.

 

wheel wells in the rear? i wouldnt waste my time doing such a small amount at once, wait till you can do like your whole floor and doors...or whole trunk, it will safe you time, and you'll notice the improvements alot better.

 

Have you already done a layer on both doors? If you haven't then just do both doors. It will be worth it. Just wait to do the wheel wells till you can get more. Also, do a search for E-dead on google. They have a cheaper and better version of dynamat. Just FYI.
