Speaker Sizes for 89 CRX

Anyone know the size of the front speakers in an '89 CRX?

I think 5 1/4 or 6 1/2 can be fit into the front.

I had to cut the back of the rain guard away a little to fit 6, 1/2s into my Civic. But they do fit with out any trouble.
Mate had to do the same thing to get 6 1/2s into his CRX as well.

Thanks for the info.
