Ok I have a 97 blazer 4x4. I just looked up and the stock alt is 105amp. Right now with the stock radio in it the interior lights dim with the lights on. It has every power option including power seats. Will 1500-2000rms be to much for the stock alt with the big 3? Do I need to look into getting a high output alt? I was planning on running caps as well. I just don't want to be stranded on the side of the road because my alt can't handle it.
