ok i acuired these from a friend dirt cheap and i want to use them instead of my stock 5 1/4ths that are in my car right now.... but the only problem is mounting. i cant seem to find any adapter rings that go from 5 1/4-6 1/2 to 4x6 so i kinda need some help in this one... any suggestions, an MDF ring maybe?
