I'm trying to understand the concept of batteries and amp hours and how they relate to draw and keeping power to your amp. I'm looking for some sort of ratio, there has to be one, right? You don't have a 3,000w system and need 20 batteries that are 80ah each. I understand the more power you run... the more alts and batteries you'd need to keep your voltage up. I know that the alternators charge your batteries, the more alternators you have, the quicker you charge your batteries because you're pushing more amps to your batteries. Alright... here's my situation; I'm looking to build a new setup in my truck, I'm gonna get (3) 350a Excessive Amperage alts, I already have 300ft of 1/0 Gauge (for several runs to the back), I'm looking to be running about 25,000w-30,000w total. I'm trying to figure out how many 12v batteries to get and how the amp hour plays into it all. Also... I'm really trying to figure out how much more it would cost to run a 16v setup. If it's like $300 more to get more out of my system... why would I pass that up? I'm currently running 5,000w system (3) 1,500w mono amps for my subs and (2) 4-channel amps that are over 400wRMS each. I'm just trying to figure this out because I'd love to go XS Power or NorthStar or Crescendo Logic or Juice Box or any other brand, but if I can get an off brand in bulk from a local battery warehouse, why would I pay more, I'd rather shop by specs rather than by brand. I'm trying to figure out the ratio of RMS Wattage (let's say a baseline of 10,000w) to alternator amperage to number of batteries and/or amp hours. If you have 2 batteries that are 60 amp hours each, it'd be the same as having 1 batteries that's 120 amp hours, right? These are the questions I'm looking to have answered.

Because he has experience with that kind of power.

I sent a friend request on here and a friend request on Facebook... we'll see. I'm just looking to see if there is a general rule of thumb for amperage (alternator) to battery amp hours based on wattage you're running.

It's going to depend on what you plan on using the vehicle for.

That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

Daily driver use, demos, and comps. I'll either do no wall or a C-Pillar wall... haven't decided yet. A wall is a big step, it's like proposing to a chick.

For a demo monster you're going to want a big reserve.

What gear are you planning on running?

Unless it's 30,000 boss watts then he's good with one batt and a stock alt.
