Ohm equation help

[KJThaDon 10+ year member]

I am trying to figure the output I would get to the subs from this setup

2500 RMS amp @ 2 ohms

3 12" sub woofers 750 RMS each wired to 3 ohms

What would be the output rms to the subs?

Any help is appreciated !

Thank you

What amp and what vc are the subs... If the final load is 3 then probably around 2k,

kicker zx2500.1 and 750rms DVC

I just cant seem to figure out the equation lol

Thanks

What specific vc are the subs... Dual 3, dual 2, dual 4?

 

[KJThaDon 10+ year member]

Sorry dual 2

Series Parallel Speaker Impedance

Huh

 

[itsblown 10+ year member]

it depends on the efficiency of the amp... and even than you cant calcuate exactly what they are getting

what are you talking about here? you're saying that there's no way to see how much power is going to the subs nor there is no tool for that either?

around 700watts rms to each take 50-100 watts

what are the speakers wired at, do you know?

I am trying to figure out in theory what it should be...

Ok, my amp is rated 2500 RMS @ 2 ohms thats the lowest imp

My subs are DVC 12"s 750 RMS x 3 = 2250 RMS

But the only way I can wire them to the amp is by going 3 ohms, right??

So how much RMS theoretically should they get running @ 3 ohms??

3 ohms

How did you come up with that answer. What's the equation?

2100/3= 700, but since your not maxing your amp, prbly 600-625ish rms to each?

I hate this site.

You'll likely rise >2 ohm anyway. That's your best bet right there.

3 ohms

(Power @ 2 ohm)(.5)+(power @ 2 ohm)/(3)

Ocorrect me if I'm wrong.
