i am installing my system over the next few weeks and i need to know how many batteries to install? i am already looking into a 200 amp alt, but i'm not sure what batteries and how many i should run. i am puting in 1 solo x 18" , 2 kx2500.1 & 1 kx650.4 plus i have a 10 farad capacitor bank

 

honestly, upgrading the main battery to an Optima, or equivalent and adding a second in the trunk would probably be more than enough with the 200 amp Alt. I'd ditch the cap though...
