Aye, will do. I'll attempt this one the rear speakers come in. I've settled in on buying a set of the Special High Performance Co-axials from Turnswitch.com., they have a set that go 3 1/2 inch deep, and have a contoured ceramic magnet that resembles the factory magnet, that should be fine. I've been buying from them for my 4 x 10 speakers in my 1979 cars, all made in USA!
I have some adaptor plug ins on the way so there will be no wire cutting.
