Speaker Question

I have a 99 Yukon SLT, and was wondering what kind of speakers it has in it. Like what size, and is there any factory amps or anything else.

I am asking this because I just put in a new head unit, and the only speakers that work are the 2 front ones. I have no sound comming from the rear doors, or the speakers in the head liner.

Any help would be appreciated.

Thanks in advance..........

Did the rear speakers work before you put in the new head unit?

i think so......i was able to get the middle speakers to work tonight, but the rear ones, still a faint sound
