Stock Cobalt LS speaker?????

i have the stock cobalt speakers in my car now and im looking to replace my speakers, deck and so on the only problem i have is its a lease so i need to find out the exact size of the speakers in there now. So i dont have to cut anything to make my speakers fit. Does anyone kno the Sizes of the speakers or a site tht can tell me? Thxs for the help

5 1/4 in the front, and the back are odd shape so I had to get 5 1/4 in the back too. As for the deck, if you wanna keep the driver info center, then you gotta get the OEM adaptor wihch is about 200$ cause it's brand new, but if you buy a deck through crutchfield, they give you the OEM for 90$.

Yea after i posted tht i called Cruchfield thxs though
