Understanding Subwoofer Impedance
Before diving into the wiring process, it’s essential to understand what impedance is and why it matters. Impedance, measured in ohms, refers to the electrical resistance a device provides against the flow of current. In simpler terms, it’s how much your subwoofer opposes the electrical current.
For dual 2-ohm subwoofers, you have several wiring options that can lead to different final impedance levels. This affects not only the performance of your subwoofers but also how you should connect them to your amplifier.
The Basics of Dual 2 Ohm Subwoofers
A dual 2-ohm subwoofer features two voice coils, each rated at 2 ohms. You can wire it in series or parallel, and each configuration results in a different overall impedance connected to the amplifier.
- In series wiring, you add the impedance of both coils together.
- In parallel wiring, you use the formula:
1 / (1/R1 + 1/R2) = Total Impedance
where R1 and R2 are the impedances of each of the coils.
Tools and Materials Needed
Before starting, ensure you have the right tools and materials at your disposal to facilitate a smooth installation. Here’s what you’ll need:
- Wire Stripper
- Screwdriver
- Amplifier suitable for low impedance
- Speaker wire (preferably 12 or 14 gauge)
- Solder (optional)
- Heat shrink tubing (for a neat finish)
Choosing Your Wiring Configuration
When wiring a dual 2-ohm subwoofer, your ultimate goal is to match the impedance of the subwoofers to your amplifier. Here are the two most common configurations:
Series Wiring
-
