Going 16v and need some advice

[Andrew2944r]

I am going to do the following and what would be my best option:

Amps include: 6 - SAZ-3500's on 16v should be around 30k watts

Have 2 XS 2400's under the hood and will power a SAX-100.4, SAX-50.4, SAX-125.2

Option 1: 3 - Alts on 16v and 1 - alt running 12v and running 10 D1600's

Option 2: 4 - 16v Alts and running 2 stepdown modules and 8 D1600's

Vehicle is more of a show piece than a daily driver, but does get driven once in a while other than going to shows. My only concern is having all 16v alts running stepdowns and something happening and the 16v frying my 12v electrical. Do I really need to have this concern running option #2? Any advice would be greatly appreciated.

i like option 1 keep the 12 volt amps running off straight amp and battery power

and no need to worry bout stressing the stepdowns

you would need more stepdowns than that, they are 25 amps continuous

option 1!

For your situation I would recommend running a 12V alt. If you want to set it up so that you can run the one alt at 12V, and switch it to 16V for comps, we can give you instructions on how to do that. It will require that you use one of our alternators with the XS Volt regulator, and you will also need a couple 200A relays.

That sounds like the way to go but when you are running all of them at 16 volts you won't have anything charging the 12volt batteries so you could only do it for competitions or demo's.

Have you thought about doing 14volt battery bank and charging just shy of 16 volts, your stock electronics are usually rated to 16volts so you would be good all around. I have been looking into this option cause MTX amps can't take over 16volt input so a couple alts charging at 15.8 and a 14volt battery bank would maximize their potential.
