Alright, I'm only running about 2000 watts rms, but I want to add under car lights, interior lights, and an in-dash video screen. Rigth now I have just the stock battery and my lights barely dim, but I just want a stronger battery just in case. I've read many threads about the Optima batteries, but I'm not too thrilled because I've heard they die alot. So I heard about Kinetik. The one I'm looking at is the Kinetik HC 1800. I want to use this as my primary or only battery in my car because its like 50 or 60 lbs. Here's the website: http://www.kinetikaudio.com/hc1800.asp. Can anyone tell if it might be enough for my electrical system, or will I need to add other components? I really don't want to mess with the alternator.
