What size speaker is supposed to go in the rear center speaker opening on a 1966 coupe? I don't want to put 2 in, so I figured what if I got one of the larger dual core speakers and put it in the center rear speaker opening. I have a dual core in the front, and it is really nice. Thanks guys.

just wondering what size and make of speaker do you have for the front, is it an aftermarket one???? looking to put one in, didn't know which would be best, thanks

It is custom autosound. That is what all my radio equipment is. I have their USA-66, with cd changer, dual core speaker in the front, and I was hoping to put a single dual core speaker in the back.

I put two 9 inch (2-way) units in the back of my 66 coupe and they sound great. Several supplier sell the package tray with pre-cut opening for that size. I did have to carve away a little bit of the opening in the metal deck underneath with a dremel-tool for the fit but if you test before hand you might be able to skip this messy step. I think you'll like two in the back rather than a single split speaker. There is just not enough separation to get a stereo effect with that set-up
