Deadening for Trunk build

Recommended Posts

I'm going to be firing my subs and port forward and sealing off the trunk from the cabin. So far, I only have my front doors and trunk lid deadened. I only bought 36 sq ft of dynamat extreme (I live 5 minutes from the factory, gotta support them haha), what should I deaden primarily first? Because I'm sealing off from the trunk, do I even need to deaden anything in the trunk?

If the trunk is sealed off, noise coming through the trunk shouldn't be a problem. If the trunk won't be seeing any sound from the subs, it won't sound bad outside the car. No reason to do anything else to the trunk that I can see.

Personally I would deaden the rear deck and make sure it's 100% sealed.

Yeah for sure I'll deaden the rear deck and I'll make a great attempt to seal it off 100% thanks to expanding foam. So basically you guys don't think I should deaden even the sides of my trunk?

If it's sealed.. No I'd deaden the rear deck since for most cars it's just flimsy sheet metal.

I'd recommend bracing the rear deck as well, usually just a piece of wood or two between the sub box and the rear deck will take care of most if not all flex of the rear deck.
