Audio for my '92 Metro
 

Just wondering if anyone knows offhand what the correct speaker size is for the speakers that can go in the hatch at the back of a Metro. I've looked around a bit but I can't seem to find anything.

I can hear the crickets chirping.

4 1/2" I think, or maybe it's just 4". Whatever the more common of the two sizes is.

crutchfield - click "car audio/gps" and choose "outfit my car" - it'll tell you.

FWIW, I use an mp3 player on a pair of noise-cancelling headphones, with the seats removed.
