I have a 2011 CC chevy. I put alpine type R comps and coax in. A pioneer hu and I'm about to put in my amps and subs. They are a Hifonics Brutus 640.4 and a 1600.1 and 2 Sundown sd2-12s. I've never messed with H.O. Alts before and don't know how big of one to get for this set up. Would a 200 do it? Or do I need a 250-270? Also I have a headache rack I built for my truck with 4 extra taillights in it and currently get a small dim/blink when I hit my brakes. I was gonna get a new batt also. Maybe a yellow top, but one guy told me to get a red top instead. Why? Could I also get away without doing a big 3 as some people have said it doesn't help that much or actually hurt them? Thanks in advance!!!
