Trust me that old AM is large and heavy. You'd have to take the dash out to get it in or out. It was in the trunk when I bought the car, so I really don't know if it would work or not. But I wasn't ever going to put it back in anyhow.
And I remember the Concordes. I looked but there were only ever one or two for sale, used. And I was really looking for something new-old. I could be wrong but I think they put those in 80s VWs.
This one rocks the house with 11 wpc, which actually is pretty high power for the time period. Depending on how I finish this, I still can hook a booster up to it - something like those old Kraco 40 wpc boosters - I'm not after the best in sound just something somewhat more period and workable. Interesting, there are no speaker cutouts in the rear deck. There's one speaker in the middle of the back seats - sort of a cutout area - and one in the middle of the dash. I can't remember if there are round holes in the doors since I haven't had the panels off in so long. So I may have to go total old school and get those Pioneer box speakers or something. NOS preferably so it may take awhile.
