8 ohm speaker wiring diagram. When the mono stereo switch is set to mono the two 8ω speakers are wired either in series making a 16ω cab or in parallel making a 4ω cab depending on which jack you use. For example an 8 ohm wiring may only read 6 8 ohm or a 16 ohm wiring may only read 12 9ohm. Myth busted real test 4 ohm vs 8 ohm speaker. The are two basic ways of connecting two speakers together either in series or parallel.
Two 4 ohm speakers 2 ohm load two 8 ohm speakers 4 ohm load two 16 ohm speakers 8 ohm load. Five 8 ohm speakers wired in parallel will have a total impedance of 1 6 ohms. Also attempting to wire two 8 ohm speakers in parallel to an 8 ohm stereo would have the same effect. Wiring configuration for 2 speakers in parallel.
Hi frank you can go either way but first a bit of maths. However increasing the resistance to more than 4 ohms of speaker resistance by adding speakers in series will split the amplified audio output from the amplifier across all the speakers in the circuit. 4 ohm speakers unlike speakers at 8 ohms of resistance keep the overall resistance on the amplifier at or near 4 ohms.
