1. ## W7's, ohm's, multiples..

So i know running 1 10 w7 your going to get 3 ohm's.. 2 w7's you get 1.5 ohm?..

Now my question is what about running 3 w7's? BTW the amp is 1 ohm stable.

3 3 ohm loads in parallel is 1 ohm. Take the reciprocal of each impedence add them up and the reciproecal of that is your answer.

3 ohm load is 3/1 So you take 1/3 + 1/3 = 2/3 flip that and you get 3/2 ( or 1.5 for 2 of them) for 3 of them you do 1/3 + 1/3 + 1/3 = 3/3 = 1

Q.E.D.

That sums it up. Thanks.

Now the 13's are D 1.5.. would two of them equal out to .75?

you could series wire the coils on each of the subs to 3 ohm. And then you could parallel wire in the 2 subs which would give you a final result of 1.5 ohm.
if you parallel wired everything then you would get .25 ohm

4 1.5 ohm coils in parallel would be .375 ohm

My bad it is .375 ohm

Daym. My SAZ would be making some serious power

9. ## Re: W7's, ohm's, multiples..

What are my options for wiring if i just ran say 1 13'' W7? 1.5 or could i wire to .75?

10. ## Re: W7's, ohm's, multiples..

So i could wire 3 w7 8's to 1 ohm? since they are single 3 ohm..?

Correct.
