So my next install will consist of 2-saz2000 and 2-15inch NS d2

and i was wondering how much AH i should have on my batteries to support my 2 saz2000 straped at 2ohm?

i know i read somewhere that if it is at 1ohm just take the fuse size and divide it by 2 and there you go! so for 1 saz2000 at 1ohm i would need a mini of 100ah battery to support it!

now i am wondering, i got a good deal on some nsb 90 (90ah) and i can't pass up the deal but they are only 90ah each and i want to get 2 of them. now will this 90ah (180ah total) be enough to support 4krms at 2ohm?

thanks for your time

i think i found my answer!

can someone please confirm this site?

http://cr4.globalspec.com/thread/32655/How-to-calculate-the-required-AH-for-ups

also i jsut worked it out and here is what i got!

200amp(current)X 0.25(about 15mins of play time) = 50

50/0.9= 55.55

55.55/0.5=110

so i will need 110ah per amp?

i think that is wrong though but i need someone to confirm my finding or someone who knwos what is going on

thanks for your time

I am pretty sure it is calculated without a charging source. You have an alt that will charge those batts and you will also not be drawing that much current at a constant rate.

good point! i never thought of that before~ thanks for bringing that into perspective!

so since i have a h/o (200amp alt) i guess i can use 2 nsb90's for 150 each!!! sweet!

thankyou so much!! you rock man!

I would say yes that 90Ah will be ok for the 2-SAZ-2000D's but if you go to a competition or try to pound at full tilt for a while it may be a small factor (but it depends since music is dynamic). I would suggest upgrading your starting battery to give you that extra AH if worried about it or it becomes a problem since you can get those batteries cheap.
