if your going to rely on batteries 12.5v isnt that low 11's would be low. what do your batts rest at 12.8 13.2 if your lucky. anything under 11.5v and id be worried.

While running you mean? They hover at 13.5V at idle with no draw, and the initial screaming subs drops it to 12.9 then slowly drops to 12.5 before I kill it (.1V / 3 seconds @ 45hZ full volume).

Need an install? Hit me up.

Sorry to hear that man... I was just looking at some used Memphis 4K's..... But that is scary I have the same basic electric as yours..

The new US amps DX I believe pulls around 250 amps AT 3200watts..

My electrical system is completely upgraded from stock. Big 3 with double 1/0, 4x 1/0 front to back, 4 Kinetik batteries and 300A alt.

Is this really "basic"? :unsure:

I agree that 12.5V drops are nothing, really. Batteries are 12.8, so realistically, you are only dropping .3V before you kill it. I know there's more to it than that, but once you pull over 300 amps, you're going to go to battery power, which is normally 12.8V.

My Ohio 300 amp alternator puts out pretty much nothing at idle, and I was told by a couple other manufacturers that in order to make 300 amps, there has to be some give, and that's charge at idle. As soon as I touch the gas, my amperage and voltage comes up to normal, but at idle, I'm also running off of straight battery power, pretty much. In contrast, a couple friends have 200 amp alternators, and theirs put out decent power at idle, and it's the same alternator casing, just mine is 300 amps, their's is 200 amps.
