My issue lies with my new lighting system. I am installing lights on my 1500 91' Sil Pick- up on a custom made roll bar. I am putting 4 100 watt lights in the rear, 2 100 watt lights in the front and 2 - 55 watt lights on the side. Do I have to get a new bigger alternaterfor the extra load or can I put a double battery system under the hood , connect them together and run off of it? Any suggestions would be nice.
