2000 elentra gls speaker replacement

Anyone know what the speakers sizes are (front/rear) I just bought a used one, but have not picked it up yet. Im guessing 5 1/4" up front and, from the looks of it, 6x9 out back? Thank you.

6X9 Back and 5.25 front
If you replace the rear speakers you might have to cut the metal a little cause the stock speakers are really small. I put in some Infinity Kappa 6X9s and i had to cut about a half inch all the way around to fith them in. It's not that big a deal. Just get some metal snips and cut little tabs about every inch then bend them back to make room. (if your speakers don't fit) The front speakers should go in with no problem.

thanks for to confirmation. I wonder if they actually 4x8 then, or do they not make such a size? I think it does exist. Anyway, thanks for the info and the advice. Just curious, im assuming you are not driving them with the stock stereo. How difficult is it to change the head unit. Any fragile parts i need to look out for? Any i assume a harness should be readily available?
