Here's my problem.
With 1000W amp and 2 12s, I get voltage drop pretty bad at idle. I'm chillin at like 12V when im slammin stopped. When I get past about 1200 RPMs its fine, well kind of. I still notice the lights dimming but the gauge doesnt drop so low.
My question is...Is this bad? I mean bad for like the accessories, fuel pump, window motors, etc. I don't really mind the lights dimming cause my HIDs dont dim like standard halogens would...if it is, what size alternator should I get? I don't have enough room to add any extra batterys.
