Looking for the size speaker we have in the dash of a 67 Coronet. A.M. Radio (of course) I want to replace it with a significant upgrade... Possibly 2-3 1/2" or whatever.
 
The dash speaker in my 82 Coronet is a 4x10. I used an adapter.plate to add a pair of 3.5" Infinities. It came out very nicely.
 
They make a dual core speaker for the stock location. Smelectro has it. Other than that, it’s adapter time. Various ones around. I’m assuming you are ditching the stock am. It will fry the transistor if you run a 4 ohm in place of the 8 or whatever oem was.
 
I just installed a pair of Kicker 4" two-way speakers in my dash. It was a pain, but I wanted my dash speakers to match my rear deck speakers, so I made a mount plate out of 1/4" ABS plastic, mounted the speakers to that then mounted the whole thing in the dash.

I'm sure 3 1/2s will be easier, especially with pre-fab mount plates, but I think the 4x10, dual voice coil speaker is the easiest way to go. Left and right share a common woofer, but have separate tweeters, so you still get stereo sound from a single speaker.
 
S&M Electro , Blaine , Minnesota will convert your radio, pre wire your system and supply speakers. Have had it done to 2 of my cars. They do nice work. You will have a 4 channel system with balance and fader, in your converted stock radio.
