Hi im looking for a good sounding set of speakers for a full size chevy Blazer it has 4x10" rear's is there any speakers that sound good in this size. The stereo is the stock one with the stock EQ. I just picked up a set of 4x6" Infinity 6412cpf reference series for the front. I don't want to add any boxs that would take up to much space thanks for any input

Another set of Infinity reference speakers would work, but the size that fits. There is no reason to go all out on your rear speakers for a couple of reasons, especially if you aren't going to use an amplifier.

I don't think infinity make a 4x10" speaker I looked but couldn't any by infinity

Sorry for not specifying this but you are going to have a hard time finding speakers in 4x10. You are probably going to have to look for a different size. I think that 4x6's will mount on the same space as a 4x10. I have never worked with 4x10 so I am not completely sure about this, but that is a good place to start.

Pioneer makes a set that sounds pretty good as a factory replacement.

i bought a pair of eclipse SP6900 6"x9" 2 way for the rear that i would buy again if you do change your mind on a box. But my friend has a pair of eclipse SE8405 and the sound just as good.
