I have a 99 suburban ls. I hooked my aftermarket stereo up. Now my rear door speakers are not working. I hooked the blue wired up to the blue and white wire to my unit still no sound. It worked with the last aftermarket stereo i had in but not working now. Please help me

In many cases following wire colours is fairly safe but aftermarket stereos don't seem to conform to any particular colour code so in order to avoid an unintended short circuit it is necessary to positively identify the function of each wire/pair of wires.
My advice is to start again, get it right this time and hope you haven't damaged the unit.
