I am about to install my Arc Audio 2500 amp, Arc Audio 4050 amp,and (3) JL Audio 10"W3V2's in my K5 and I have a newer 63amp altenater and a 6 month old big 800 or 900 CC amp battery. My question is will my stock charging system handle 1,500 watts? I obviously won't be running full power all the time or even half power probably, but will I still have problems with my lights flickering and the alt. not being able to keep up? My guess is 63 amps isn't near enough so what should I do if it isn't? dual batteries good enough? flux capaciter? dual batteries and a bigger alt. around 100 to 140amps? Last question. /forums/images/graemlins/tongue.gif how many amps does it take to power 100 watts? (trying to get an idea how much power my system would use) Thanks!
