BATTERY HELP

About to start a build with 4 of the sundown 2500 when they are available what batterries would you recommend and how many. going to be running a 200amp alt. running between 14 and 16 volts.

Well XS says the D3100's can handle from 4000-5000 watts per battery so 2-3 would be sufficient.

When you say running between 14 and 16 volts are you talking about the alternator? You shouldn't charge our 12v batteries over 14.9volts.

How many watts total are you going to be running? What are you going to be using it for spl, daily driver, etc....?

Total power I am guess will be at least 10000 wats, it will be mainly for spl but I will drive it occasionally. The alt. will have a external regulator that will be adjustable up to 16v so that s what they told me. But I am just trying to see what I need to sustain the amps at a good voltage for bass race, bass boxing, etc.

For the top performance I would recommend 4 D3100s, but you could probably get by with 3. If you are running at 10,000watts then you have about a 1,000amps of pull and the alternator is only going to put out 200amps of charge, so you need plenty of reserve power in your battery bank. Your voltage is going to drop some, but not much with 4 D3100s.
