Understanding the Basics of Subwoofer Wiring
Before we dive into the wiring process, it’s crucial to understand the basics of subwoofer wiring. A subwoofer is a type of speaker designed specifically to produce low-frequency sounds, typically below 80 Hz. Subwoofers usually have a single voice coil, which is the part that converts electrical energy into sound waves.
When wiring two subwoofers together, you’re essentially creating a single, more powerful subwoofer system. This can be achieved in two ways: series wiring and parallel wiring. We’ll explore both configurations in more detail later in this article.
Series Wiring vs. Parallel Wiring: What’s the Difference?
Series wiring and parallel wiring are the two most common configurations used when wiring two subwoofers together. The main difference between the two is how the subwoofers are connected to the amplifier.
Series Wiring:
In a series wiring configuration, the two subwoofers are connected one after the other, with the positive terminal of the first subwoofer connected to the negative terminal of the second subwoofer. This creates a single, higher impedance load for the amplifier.
Parallel Wiring:
In a parallel wiring configuration, the two subwoofers are connected separately to the amplifier, with each subwoofer having its own positive and negative terminals connected to the amplifier. This creates a single, lower impedance load for the amplifier.
