How many inches is the back speakers in a 1999 Daewoo Lanos?

My back speakers in my car are stuffed, one doesn't work at all and the other one rattles, I was wondering how many inches they are so I could buy new ones.|||I looked it up online and they claim to 6 3/4" (most 6.5" will fit too) speakers in the rear and 4" in the front. Some nice Kickers or JL Audios would sound nice in a smaller car like yours. Worst case, you just take it apart and find out. Hope this helps a little.|||prob 6.5 but others will fit
