hi i have a 1990 honda accord dx and i was wondering if anyone knew how to remove the stock stereo? any help is greatly appreciated thanks

 

On my 1993:
pull out ashtray
remove two screws that hold ashtray bracket and remove bracket
there are two hex head bolts that thread up into the bottom of the radio bracket
remove those two bolts and radio should slide out.
disconnect wiring harness and pull out antenna plug
viola!
