so im trying to wire 4 12", 16 ohm speakers to 8 ohms. i cant find any diagrams anywhere.
anyone know how?

Re: Wiring confusion
btw, total load being 8 ohms. not stereo, is this even possible?

Re: Wiring confusion
Two equal loads wired in series doubles the impedance.
Two equal loads wired in parallel halves the impedance.
There's no way to do it with four 16 ohm speakers. You need 8 ohm speakers to get an 8 ohm total load with four speakers. Normally this would be done by wiring two pairs in parallel (making them 4 ohms per pair) and wiring the pairs to each other in series. If you do that, you'll get 16 ohms total. Wiring two pairs each in series, then wiring the pairs together in parallel does exactly the same thing.
Sorry.

Re: Wiring confusion
KC,
You may want to include the amp in question. That is pretty important information.
Full parallel with (4) 16 ohm speakers will get you 4 ohms.
Full series with (4) 16 ohm speakers will get you 64 ohms.
Series/Parallel with 16 ohm speakers will get you 16 ohms.
Avatar Speakers has a pretty good diagram page.

Based on the information you have given me, I would do one of two things:
1. Wire 2 speakers in parallel to get 8 ohms. Only using the 2 speakers.
2. Wire all 4 speakers in series/parallel and then take the actual measurement with a multi-meter. The actual measurement is usually less then the math suggests. An 8 ohm speaker is usually around 5.3 ohms. With that measurement you can make a better judgement.
Hope this helps.

Re: Wiring confusion
Word of caution: 5.3 ohms may be the reading you get, BUT...that is DC resistance, not impedence. To measure impedence, you would need an LCR bridge that measures the drop across a coil at a given frequency to determine nominal impedence.

Re: Wiring confusion
100% true, the measurement would be resistance and not impedance.
