Stock is a 6 inch ROUND speaker. I took mine to a speaker store and they sold me 6x9's so I had to do some cutting.
For the front speakers you need to take off the dash pad and the rear speakers you need to take off the rear speaker panels.
The 1989 Toyota Corolla Weygand rear speakers can be found in the side compartments of the rear of the vehicle. There will be a speaker on each side.
six inch
it really takes 6x8 for both front and rear but 5x7 will work too. they are almost interchangeable.
Front: 6x8x2.5" Rear: 6x8x2"
in the rear they are 6.5 inches and in the dash it is 4 inches.
6x8 , front and rear speakers. Can use 6x9's by removing the factory bezel.
HI according to crutchfield.com you should have 4X6" speakers in the rear and 4" in the front hope this helps
6X8 most speakers are 6X9, pioneer makes a factory replacement for Ford/Mazda that is 6X8
6x9
4x4 = 4.3
I have a 1989 civic dx: door 6.5", rear deck, 6.5"
