I need to know the specs for my blazer's speakers. I know I made a thread earlier but I need to know the mounting depth and someone said the back door is a 6.5 but it looks to me like it is a 6X9. Any help would be great!

 

I've got a 99 4 door that I just replaced the rear door speakers. The size is 6.5". Be careful to measure the depth of the existing speaker before buying new ones. Some of the replacement speakers I looked at were deeper than the space allowed. I went with a pair of Pioneer two way 250 watt that fit nicely. I only had to drill new holes thru the speaker flange to match up with the holes in door speaker bracket.
