I made a set of Front door adapters for my 03 Nissan Sentra, and made an extra set. made of 3/4" MDF to put aftermarket 5 1/4's or 6 1/2's. Should fit other years and models, I am just not sure years and models. If you buy I will cut the speaker hole, you just give me the size it need to be cut to. $20 shipped
