When I got my set, one of the speakers was defected. I emailed them and send it in. When I got a replacement, Surround wasn't glued on. So they sent me another one. It was fine, but looked like it was b-stock.
How strong do I need to make it? Will 1 layer of mat be enough
I will be putting 6.5 woofer and tweeter.
Yea, I was talking about grit for fiberglass and then for body filler
