Sound dampening rear door?

[GeneralNoobzor]

I would use search function, but isn't working for me.

Everyone knows those rear doors sound like shit with subwoofers in the hoe. Anyways, I have 2 l7 10"s backfacing towards the door in a 2004 tahoe, anyone have any ideas how to damped the rattle? I took off the plastic panels and it sounds amazing. How can I keep them on there and have it still sound great!? Thanks!

Aha, funny thing I did this before I read the posting. Works great. I got alot of foam from work and just packed it in the tailgate and used adhesive foam stripped and it sounds great. Thanks for the help man . Spent $5instead of the dynamat expensive shit....
