sound barrier for a wall methods

[shizzzon 10+ year member]

snoopdan uses pink panther insulation to seal around his box so it acts like a wall in his cherokee.

I just got done building my box in my scion tc with 4 15s and i need to seal around it so it can act like a wall.

I was gonna use pink panther but have 2nd thoughts because it states that it's purely a thermal barrier, not acoustic barrier.

Is there any methods u guys use or can persuade me with facts as to continue to go with pink panther insulation or is there a better method?

Well there's going to be a big difference between using fibreglass insulation as per manufacturers specs, and cramming in as much as you possibly can. The latter will provide a pretty good temporary seal.

A more permament, and far messier solution would be expanding foam, which would be superior to densely packed fibreglass insulation when it comes to stopping acoustic pressure.

Another option would be bulk closed cell foam, crammed in like the fibreglass insulation.
