I have been researching this for the past week and think i have come to a solution. could someone please give me some opinions on my plan and confirm it will work well as intended.

i would replace my two starting batteries with these: http://www.remybattery.com/Deka-Inti...ery-P9239.aspx

I will install this: http://www.overstock.com/Home-Garden...0/product.html

and install this in the engine bay or perhaps along the frame: http://www.onlinecarstereo.com/CarAu...k_KHC2000.aspx

this will give me 2 980CA batteries to run my engine, headlights, and winch.
the second 2300CA battery will run my stereo, plow, power inverter, and off road lights. the two battery banks will be separated by teh isolator.

my stereo is alpine component fronts at 300W, rear coax at 150W, and a 18" fi BTL sub at 6,000W. my power inverter is a 5000W, i have 4 15A off road lights, and a 12,000Lbs winch.

my alternator is rebuilt with a HO kit, its about 180A.

i would like to install a bridge between the 2 batter banks with a 400A switch so i can bridge the batteries and bypass the isolator. this would be there in-case i want to run my headlights for an extended period or i drain my starter batteries i could start the truck off my second battery bank by flipping this switch.

thanks.
