It is common for players to connect two 4×12 cabinets to a single amplifier to form a complete stack, referred to as a half stack. A 4×12 cab usually has 16 ohms in resistance, so connecting two in parallel reduces the overall resistance to 8 ohms. Most amps on the planet can drive an 8-ohm load, making this a popular configuration. For the record, many venues aren’t thrilled when you show up with a complete set of cards for some reason.
When you link two 4×12 cabinets together, the total resistance is 16 ohms. How to Wire a Marshall 4×12 in Series and Parallel. The positive conductors are four 16-ohm cables. Negative wires are those that are black. Speaker terminals should be positioned closer to the middle of the cab.
Always double-check that your amplifier’s head is set to the maximum possible load. Set your amp’s output to 8 ohms, for example, if you’re using two 16″ cabinets for a total of 8″. A 4-ohm total load could be achieved by using two 8-ohm cabinets. Then set your head’s resistance to 4 ohms.
Connector choices when wiring a 4×12 ohm speaker
In many cases, users use the same cabinet to house quarter-inch phone ports and Speakon. This allows you to plug in your cabinet regardless of which is currently in use.
1/4-inch phone jacks cannot reliably support over 500 watts of electricity. If your box is used at a power level of 500 watts or above, you should use Speakon connectors.
Which connector is most suited to your needs?
The majority of guitar and keyboard amplifiers use 1/4 inch phone connectors to connect to their speakers.
Speakon connectors are used by some of the more powerful bass guitar amplifiers on the market.
Low to mid-power PA systems often have speaker connections with 1/4-inch jacks and banana plugs. Speakers are only seldom used in these systems.
Many high-powered PA systems only have Banana plugs or Speakon as input and output options.

1. Internal wire
If the speakers receive no more than 500 watts, utilize eighteen or sixteen gauges (AWG) wire. If the speakers are exposed to 500 watts, use a 16 meter (AWG) or smaller wire.
Because they are frequency limited, Piezo and Voice-Coil tweeters consume less power than other tweeters. Wire gauges of twenty or eighteen gauge (AWG) are sufficient. A wide variety of wires is available in hardware and auto parts stores. The copper-stranded wire should be used. Solder all of the internal connections to the components together.
Do not turn the power amp on or off while still powered up.

For four musical instruments, one total impedance is hardwired—Piezo Tweeter on a Monophonic System. Four musical instrument speakers and one piezoelectric speaker are included. The circuit is hardwired to have a single total impedance.
Voice Coil Tweeter in Mono. One Voice Coil Tweeter and four Musical Instrument Speakers One complete impedance is hardwired. The stereo is included within the same cabinet. 4 Speakers for Musical Instruments The use of a Switch craft 14B Stereo Jack allows for selecting mono or stereo sound.

Wiring configurations for your speakers
Speakers in the cab can be replaced for a very reasonable price, resulting in a dramatic improvement in tone. If you’re contemplating replacing your speakers, you’ve come to the proper location! Even though it is not a complex process, it is vital to understand how the speakers are linked and some of the ramifications of connecting many speakers simultaneously.
It is common for players to connect two 4×12 cabinets to a single amplifier to form a complete stack, referred to as a half stack. A 4×12 cab usually has 16 ohms in resistance, so connecting two in parallel reduces the overall resistance to 8 ohms. Most amps on the planet can drive an 8-ohm load, making this a popular configuration. For the record, many venues aren’t thrilled when you turn up with a complete set of cards for some reason.
The impedance of certain 4x12s is 8 ohms, and they contain a quartet of Eight-ohm speakers. Following the wiring schematic will still work because it is still a series-parallel setup.
Always double-check that the amplifier head is adjusted to the maximum load. For example, if you have two 16-ohm cabs for a total of 8-ohms, you should tune your amplifier to 8 ohms. Alternatively, you could utilize two 8-ohm cabinets to create a total load of 4-ohms. In such a case, set your head’s resistance to 4 ohms.
It is never good to link cabinets with various impedances since an amp will behave strangely if there is a mismatch. A total load of a 16-ohm cab or an 8-ohm cab is 5 1/3 repeating-ohms, yet the 8-ohm cab receives twice as much power as the 16-ohm cab, which isn’t particularly impressive. If you have different impedances in each cab, you should utilize other heads for each cab and set each to the impedance of the cab they belong to. That is going to sound fantastic.

Conclusion
It would be best to use a separate Voice Coil tweeter for each Woofer because the Cross-Over capacitor is based on impedance. However, if the impedances run individually, switching impedances will not affect the crossover frequency.
If you cannot do the wiring successfully, seek help from a professional.
