Any ideas besides the two in one speaker replacement for the original under the dash mono speaker for a 68 convertable? I don't want to cut into the doors at all. I'm either going to hide a radio in the glove box or replace the original AM radio, but don't know where I can put any speakers.

 

Try the search function for "kick panel speakers". If you have an A body, someone is making repro kick panels designed for speakers. You can just swap them out for you originals.
