14volt vs. 16volt?

[TnT_Sounds 10+ year member]

Well here's a little dillema I'm stuck between. I have a dual alternator setup. Now I can either run a 14volt alternator as my second one, or a 16volt alternator.

The setup I plan to have is some IA 40.1's on 6 12's. This is strictly a daily low end setup. So I would be doing quite a bit off demo'ing at almost "full tilt" at times.

Would it be better to run 2 14volt alternators with almost 600amps of juice available?

Or run the dual as a 16volt and have a decent battery bank?

just do 12v, you dont need 16v, mostly everyone that has 16v are competition ppl

I assumed the higher charge rate would've been better for the demo'ing that I would come too a lot.

lol since when 10k watts =strictly a daily low end setup

Whatt'd be cool is to have both, but have a DC-DC 14V-16V inverter setup. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I personally would say, depending on how many 40.1s you have, determines your answer.

16V is nearing the threshold of the car's stock electronics is it not? Because if you're maintaining 16V, the alt will actually be charging at an even higher voltage, might fry your car's shit. However, if it's charging at 16v, chances are while doing big draws you should stay steady at 14-15V right? Also, would having 14V and a 16V alternator together be weird? I don't know, with them charging at 2 different voltages, wouldn't that **** with some stuff? Is it possible for one alt to try and push current backwards through another if it's charging at a higher voltage?

I'd go either all 16 volt or all 14 volt. 14 volt would probably be more practical.

I have 3 but I only plan to use 2. Also I have a wide range of subs to choose from so that also determines what I would need for power

You sir are a noob. The 14volt alternator is its own to run the trucks 12volt system with its own 12volt battery.

The 16volt alternator would be charging 2 other 16volt batteries under the hood which are their own that strictly power the amps.

Personally, i would run a 14volt based system for everything, then run a 16 volt based system for strictly the substage

Thats exactly how it would go...

14volt for the mids and highs amp

16volt for the 2 IA 40.1's

sounds like me and you have very similar projects in the near future //content.invisioncic.com/y282845/emoticons/sneaky.gif.7189749b3a3f769e8815b47e8ae87f88.gif

Hopefuly I get someone who knos what they are doing

I'm planning on ordering my batteries next week.

You CAN have 2 completely different voltage systems, if you have the room for alts. It's totally fine, just use common ground for everything and you're good.

What I was talking about is not really heard too often, simply for the fact that such inverters can be a bit expensive, but a random idea is to have both large supplies, have a high watt DC-DC 12V to 16V inverter, and supplement the 16V line when needed. That's overkill, but if I were to do it personally, I would build the inverter and do that. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Remember,

8kW*1.2=9.6kW

@16V that is 600A

@14.4V that is roughly 670A

@13.8V that is roughly 700A

@12.8V that is 750A

what are you talking about an inverter for?
