2x12 speaker cabinet wiring diagram.

The big thing to consider regarding speaker installation is the power your amplifier outputs. The diagram below shows the wiring of a marshall 2x12 speaker cab having a mono stereo selection switch and two specialized input jacks. The conventional wiring is called series parallel and the speakers themselves are each 16 ohms. In essence there are two ways to wire up a 4 speaker cabinet that both wind up with the cabinet having the same impedance as any one of the individual drivers or in other words a cabinet with four 8 ohm speakers that ends up with a total cabinet impedance of 8 ohms.

So if you have a 4 12 speaker cabinet and a 100w amplifier four speakers rated at 30w would be safe. The two main methods of arriving at this means are as follows. 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. A typical 4x12 cabinet is rated at 16 ohms.

Again assuming we re using the same 8 ohm 50w guitar speaker cabinets the impedance of the cabinet is 2 ohms 8 4 2 and the power handling is 50w x 4 or 200w. 1 shows how to connect four 16 ohm speakers in a series parallel configuration. The cabinet is rated at 120w. Maybe you need some help with wiring said cabs.

Many people have asked how to wire up a 2 speaker cabinet that can have an extension speaker cabinet usually another 2 speaker cabinet plugged into it when desired. And here s the wiring diagram for four guitar speaker cabinets wired in parallel.
