Mixed Loads

I know its dumb, but the subs are here and I'm bored. What load would an amp "see" from a 2ohm(dual4) sub and a 1 ohm(dual2) sub bridged?

1.5 or 3? but from what i hear its not a good idea, im sure someone will tell you why cause im not real sure

Someone have any scientific answers? I love those. LOL! Really though, would the sus get equal power?

Im interested in this as well.

im not sure even if the higher impedance sub would play electricity flows through the path of least resistance.

idk either, id like to know as well. cause there are 3 ohm vc's and odd numbers like that, but theyre on one sub. but i think i seen somewhere else its not good, but never explained why.

Someone has done this before and just won't admit it. Everyone was a noob at one time so someone tell me whats the deal with this please

wire it up and get a dmm. if you don't have one then go buy one, that way the rest of us can know //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

with the voice coils and subs all in parallel the amp will see .667 ohms

1/(1/2 + 1/1) = .667

.67, not a good idea. i believe it is the lower impedance woofer (dual 2) that will get the most power from the amp.

you will get uneven power flow between the coils. one driver will try to play harder than the other.

1/(1/2 + 1/1) = .667

Thats it.

Your dual 2 ohm sub will be getting more power and it will probably sound like poo.

if he wired the 4 ohm sub in parallel and the 2 ohm sub in series he would have more than .67 ohms of resistance right?

the point is.....DON'T DO IT!

yes, you can wire the dual 2ohm as 4ohm, and the dual 4ohm as 2ohm, giving 1/(1/2 + 1/4) = 4/3 ohm.

in neither case would the speakers get equal power, limiting usefulness. This is not something you would plan to do.
