Wiring 5 Speaker 8 Ohm
Ohms most speakers have an impedance of either 4 8 or 16 ohms ω.
Wiring 5 speaker 8 ohm. In example 1 we have a 50w amp with an 8 ohm output impedance. Since there is only one speaker it could experience the entire 50w from the amplifier. It has been matched to one 8 ohm speaker. Two 8 ohm speakers in parallel is equal to 4 ohms total that the amp will see.
To push more air several speakers always of equal impedance can be wired together in a cabinet. In this case we recommend choosing an 8 ohm speaker with a rated power of at least 100w. A home stereo for example may often list 6 16 ohms as being ok for use. For 30 watt 60.
The recommended speaker impedance ratings are usually listed above the speaker wire posts. It s cost effective and easy to work with. Two 4 ohm speakers 2 ohm load two 8 ohm speakers 4 ohm load two 16 ohm speakers 8 ohm load. Wiring configuration for 2 speakers in parallel.
Thick wire 12 or 14 gauge is recommended for long wire runs high power applications and low impedance speakers 4 or 6 ohms. Power handling as a rule of thumb when mixing speaker types in a two speaker cabinet maximum power handling is 2 x the lowest rated speaker e g. Also attempting to wire two 8 ohm speakers in parallel to an 8 ohm stereo would have the same effect. For relatively short runs less than 50 feet to 8 ohm speakers 16 gauge wire will usually do just fine.
