Wiring Diagram of Alpine SWR-12D2 Subwoofer
Wiring the Alpine SWR-12D2 subwoofer is relatively easy, as it is a dual voice coil subwoofer. There are two ways to wire it, depending on your preference and the amplifier you have. Let’s take a look at each of them.
Option 1: Wiring in Parallel
Wiring the Alpine SWR-12D2 subwoofer in parallel means connecting the two voice coils in parallel. This will result in a 1 ohm load, which is not recommended for most amplifiers. However, if your amplifier is rated for 1 ohm, this configuration will give you the most power output from your subwoofer. Here’s how to wire it:
- Connect the positive terminal of one voice coil to the positive terminal of the other voice coil.
- Connect the negative terminal of one voice coil to the negative terminal of the other voice coil.
- Connect one positive terminal to the positive amplifier output.
- Connect one negative terminal to the negative amplifier output.
Option 2: Wiring in Series
Wiring the Alpine SWR-12D2 subwoofer in series means connecting the two voice coils in series. This will result in a 4 ohm load, which is a more common and recommended load for most amplifiers. Here’s how to wire it:
- Connect the positive terminal of one voice coil to the amplifier’s positive output.
- Connect the negative terminal of that voice coil to the positive terminal of the other voice coil.
- Connect the negative terminal of the second voice coil to the negative amplifier output.
Frequently Asked Questions (FAQ)
1. Can I wire the Alpine SWR-12D2 subwoofer to a 2 ohm load?
No, the Alpine SWR-12D2 subwoofer cannot be wired to a 2 ohm load. It has dual 2 ohm voice coils, which can only be wired to a 1 ohm or 4 ohm load.
2. How much power does the Alpine SWR-12D2 subwoofer need?
The Alpine SWR-12D2 subwoofer has a power handling of up to 1000 watts RMS and 3000 watts peak power. It is recommended to give it at least 500 watts RMS for optimal performance.
3. How do I know which wiring configuration to use?
The wiring configuration you use depends on your amplifier’s rating and your preference. If your amplifier is rated for 1 ohm, you can wire the subwoofer in parallel for maximum power output. Otherwise, wiring it in series at 4 ohms is a more common and recommended configuration.
4. Can I wire two Alpine SWR-12D2 subwoofers together?
Yes, you can wire two Alpine SWR-12D2 subwoofers together in either series or parallel. However, make sure your amplifier can handle the load and that the wiring is done correctly for optimal performance.
5. How do I know if my wiring is correct?
To know if your wiring is correct, use a multimeter to measure the impedance of the subwoofer. If it is the same as the load you intended to wire it to (1 ohm or 4 ohms), then your wiring is correct. Otherwise, you need to check your connections and wiring configuration.
Conclusion
Wiring the Alpine SWR-12D2 subwoofer is easy and straightforward, as long as you follow the wiring diagram and understand the specifications. Whether you choose to wire it in parallel or series, make sure your amplifier can handle the load and that the wiring is done correctly for optimal performance. With the right wiring, you can enjoy the excellent sound quality and power handling of the Alpine SWR-12D2 subwoofer in your car audio system.
