I have two 4 ohm speakers that I want to wire in series for 8 ohms.
I have tried both series and parallel wiring and it always reads 2 ohms on the multimeter.
I understand that the multimeter will not be exact and there is a general formula where the reading will be below the speaker ohm rating.
I have wired some 8 ohm speakers together and got readings that made sense 13 ohms in series and 4 ohms in parallel. However the two 4 ohm speakers together always read 2 ohms whether they are wired in series or parallel.
Any help would be appreciated.

I'd say operator error or faulty meter. Maybe replace meter battery.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

also, compare against a "standard"
What does a 10 ohm resistor ohm?
Went Class C for efficiency

Sluckey, Sir you are correct. Operator error.

Thank you and shooter for replying.
