LMFAO!@!#

Maybe for bass.... Not for anything else. EVERY other speaker should have as few reflections as possible.

Dynomatt? Thats going to do NOTHING other than make your trunk heavier. What you need to do is find a way to have the sub firing directly into the cabin with a somewhat airtight seal.

If you don't want to do that, then find a way to make the trunk lid stay put. And no, dynomat doesnt do that. It just makes it heavier which lowers the resonant frequency of the trunk lid. Unless of course you use it to wedge between the top of the lid and the seal...

The only thing that tames sound is cornings 707 and similar products. They turn sound into heat. THAT is how you handle resonances.

That "pro" is just trying to sell you ****, not help you.
