Every time the a/c compressor kicks in my 1994 suburban, the truck wants to go off, the battery voltage goes down to 8 volts. I'm willing to install two batteries in parallel, but I dont know if it is a good idea and I dont know if it will help. Also when I turn the volume up in my stereo (aftermarket) the head unit turns on and off. Would two batteries help with my situation?
