MAXSPL_153 Posted September 21, 2010 Report Share Posted September 21, 2010 ok so i know its not uncommon to run big systems with not enough power, or its not uncommon to see rather. so how much power IS enough ? i dont want to starve my setup or just barely squeese buy , but i dont want to overkill it ether. so whats the formula to determine how many alts. (if i need more than 1) how many batts. if any extra , how many supply amps the alts have to be to run efficent ? i am installing (4) soundstream xxx6500's so i dont need anything to crazy ie : SMD's charging system or JP's quad setup but i want to have the power i NEED . thanks in advance for any help. take care guys !

All I know is Watts = Amps x Volts, but I don't know how to stack the charge from multiple 12v batteries.

Socky Posted September 21, 2010 Report Share Posted September 21, 2010 You might need 2 300amp alts and a big battery bank such as 7-12 batteries.

kirill007 Posted September 21, 2010 Report Share Posted September 21, 2010 (edited) 15000W= atleast 2 300amp alternator's and 4-5 huge (xs power) batteries. It all depends on you're goals... and we don't know them. Edited September 21, 2010 by kirill007 Quote Thinking is the root of all problems... You ALWAYS get what you pay for.

n8ball2013 Posted September 21, 2010 Report Share Posted September 21, 2010 whats funny is you mention xxx6500ds. And nothing too crazy. Well Those amps are current hungry. You will need it .

MAXSPL_153 Posted September 21, 2010 Author Report Share Posted September 21, 2010 GEEZE ! that many batterys ?! i didnt think it would take that much . thanks dub7 for that formula i think ill mess with it and try to comee up with something .. i sent dom an email from irragi and see what he reccommends , but i was just curious on how to figure this out for myself . (if i just keep asking for the answers how will i learn anything) might be a stupid question but are so "many" batterys needed? i kinda was thinking with the alt upgrades 1/amp would have done the trick .. then again ive never ran more than 3 amps and even then i only had 2 aux. batts.

MAXSPL_153 Posted September 21, 2010 Author Report Share Posted September 21, 2010 Im not sure where you got 15K from, but the XXX6500D's do 6500watts @ 1 ohm, so 4 @ 1 ohm = 26,000. So, @ 14Volts you're looking at approximately 1850 amps of current draw... Dom has been MIA, hence why Steve Meade, is now using Mechman alts. Shoot them a PM or Email, you have a better chance of seeing God than getting a reply back from Dom... ok will do on the PM & holy %^@* . 1850 amps of draw ?! so i need 2K + amps on demand ?

Hate to thread jack but could anyone answer my round about question? If watts = Amps x Volts, what if i'm running 3 12v batteries? Even though there's 3x 12v batteries, that wouldn't make my equation 85ax36v = 3060w would it?

I talk shit on other forums like a little bitch and hope i don't get caught out on the street. Link to comment Share on other sites More sharing options...
