Speaker locations

[pedwar0728]

I picked up a 92 Yukon 2dr a few months back and I've been enjoying the truck. I've been interested in upgrading the sound system but it only has rear speakers(4x10) and the dash speakers(4x6). Is there anywhere I could easily add some 6 inch speakers around the back seats? I have some sitting around and I'd like to install them.

Upgraded door speakers are what will give you the most bang for your buck. Do you have speaker grills at your passenger door panels?
