make them with MDF and a router table.
I'm going to make a custom box and racks for my subs and carputer and I'm looking for those 10" wooden rings people use to fabricate the sub location before mat and fiberglassing.
Anyone have a link to where I can buy these online?
check your local car stereo shop. I know that the one where i had my subs installed had alot of them laying around, and i'm sure they'd be reasonable to sell them to ya.
