Wiring a 4x12" cab to 8 ohms

Does anyone know how to wire a 4x12" cab with 16ohm speakers,to an 8 ohm load? Is it possible?
Thanks!

I don't think so..

Wiring them in series-parallel will void a 16 ohm load...

all parallel will void a 2ohm load....and all series will void a 64 ohm load......


Unless I missed something....

The best he could do is wire 2 speakers in parallel for 8 ohms. But only 2 speakers. The other 2 would have to go unused...

If it's important to you, modding the amp to accept a 4 or 16 ohm load is relatively easy to have done.

No way to get 8ohm out of that speaker setup you described. You could, however, wire it in series-parallel (to yield a 16ohm load), then run some sort of dummy load at 16ohms in parallel which would net 8ohms.

That's what I thought.My amps accept 4,8,16 ohms,so matching isn't the problem.I just like the sound of a 4x12" cab running at 8 ohms.I guess I'll just put in some 8ohm speakers. Thanks for the reply's.

That would have been my second suggestion....get new speakers....

Or just run it stereo parallel for dual 8 ohm.

Yes - all parallel is 4 ohms. I'm sure of it since I not only did the math, but did the mod on a 16 ohm cab...
