You should be fine. My system totals 860 watts rms and my 105A alternator handles it without a problem.

You may need to upgrade the Big Three though.

yea.......i have 1200 watts rms and a 90 amp alt......your lights may dim a bit but i really dont even think that will happen

my rps drop like 200 and btw i think something might be wrong with my charging system becuase any eletric i turn on in my car my voltage drops. (ex: wipers, hazards, ect...)

does it drop like .1-.5v then pick back up when ever you turn anything on? if so it seems normal as my car does that. you might just want a stronger battery + run the big 3.

nothing too noticable should happen. i have an old chevy s-10 with a 70 amp alt with a 500-600 ish watt system and i dont even get dimmage.. my hc 600 is also not hooked up.
