What size are stock speakers in a 1994 Toyota corolla?

Answer

In my corolla they are 6 1/2 in the rear and front also i think 6 1/2 too or go to www.circuitcity.com and go to car audio section and input car's info.

Try to use Toyota speaker adapter plugs so you don't need to cut wires and mess the electric system up. You can get them from Ebay or Amazon.
