- Wattage: Wattage is the measure of a speaker’s power handling capacity. It’s measured in watts (W) and is usually indicated on the speaker’s label or documentation.
- Polarity: Polarity refers to the orientation of the speaker’s terminals. Most speakers have a positive (+) and negative (-) terminal, and it’s essential to ensure that these terminals are connected correctly to avoid damaging the speaker or amplifier.
Series Vs. Parallel Wiring
When wiring 4 speakers, you have two primary options: series wiring and parallel wiring. Each configuration has its advantages and disadvantages, which we’ll discuss below.
- Series Wiring: In a series wiring configuration, the speakers are connected one after the other, with the positive terminal of one speaker connected to the negative terminal of the next speaker. This configuration is useful for increasing the overall impedance of the system, but it can also reduce the overall wattage handling capacity.
- Parallel Wiring: In a parallel wiring configuration, the speakers are connected between the same two points, with each speaker having its own separate connection to the amplifier. This configuration is useful for increasing the overall wattage handling capacity of the system, but it can also reduce the overall impedance.
Series Wiring Configuration
