Dynamat will help elimiate the vibration and increase db's.

the thing is there are some wires and the factory amp is below  i was thinking if there is way insulate bettter

or making a box in the hole in there

tcss do you know where can i purchase this box does anybody sells to retail 

thanks jose

i'm in fort washington md i just open a shop but i know that jl only sells it to authorized dealers

That is correct, you need to get it from a JL dealer. I was only suggesting it because by the time you pull down the panel and make a fiberglass enclosure you probibly will spend more on time and materials then the Stealth Box would cost. Bite the bullet on the box and make money on the rest of the job.

Congrats on your new store. Hope it's a success.
