[QUOTE="Villeza1, post: 8120902, member: 608393"] First of all, it's not going to draw that amount of amps 100% of the time. The alternator is just going to recharge the batteries. As long as he doesnt play his system full tilt 100% of the time giving the alternator no chance in recharging the battery bank, then he will be fine with just adding two additional batteries in the rear with the added equipment. I had 6 XS Power D3100 with a stock large case GM alternator (105A idle/130 max) powering 2 RD D9's .4 ohms nominal each for months, no issues. [/QUOTE]
