Hey, I've searched high and low for a thread with information, but the only one i found was a yaer old, and no one has replied to me in 3 months.

Anyways...can someone explain to me exactly how to make spacers?
i'm getting kicker ss 6.5" components. They require 2-13/16" mounting depth. And a mounting hole diameter of 5-7/16"
It woudl be great if someone coudl post pictures of how to make spacers...
thanks a lot
