Question about Audio & Video Receivers
Wiring a single speaker won't change Ohms.
More than one is a different story.
Parallel wiring is what you're looking for:
Say you have two speakers and one speaker wire.
The positive speaker wire is connected to the positive terminal of each speaker. The same for the negative.
Wiring speakers 'Parallel' will lower the overall impedance according to the following formula:
Say your speakers are 4 Ohms.
Then the formula would be:
1/Rtot=1/4 + 1/4
1/Rtot=1/2 (or .5) Now isolate Rtot
Rtot = 2 (Try it on a calculator)
So two 4 ohm speakers in parallel reduces the impedance to two Ohms.
