What are the speaker sizes of my s10 blazer? I think I have 2 in the back and 2 in the front but i could be wrong. Does anybody know the sizes? My manual doesnt say

 

4 inch or 4x6 for dash. rear speakers are 6x9's

 

Thanks, I found that out last night so I bought 2 sony 6x9's for the rear and 2 sony 4x6's for the front. The rear ones are 240 watt and the front are 140 watt. I still need to hook them up because i got them last night at 11. I'll let ya know how they sound.
