The Alpine SWS 12D4 is a high-performance subwoofer that requires proper wiring to achieve optimal sound output. In this article, we will discuss the wiring diagram for the Alpine SWS 12D4 and provide step-by-step instructions to help you with the installation process.
Wiring Diagram
The Alpine SWS 12D4 has a dual 4-ohm voice coil design, which means it can be wired in parallel or series to achieve different ohm loads. The following wiring diagrams show the different options available.
| Wiring Option | Impedance | Power Handling |
|---|---|---|
| Parallel – 2 ohm | 2 ohm | 750 Watts RMS / 2250 Watts Peak |
| Parallel – 8 ohm | 8 ohm | 250 Watts RMS / 750 Watts Peak |
| Series – 8 ohm | 8 ohm | 250 Watts RMS / 750 Watts Peak |
| Series – 16 ohm | 16 ohm | 125 Watts RMS / 375 Watts Peak |
Parallel Wiring – 2 ohm
If you want to wire your Alpine SWS 12D4 in parallel to achieve a 2 ohm load, you will need to connect the positive terminal of one voice coil to the positive terminal of the other voice coil, and the negative terminal of one voice coil to the negative terminal of the other voice coil. Then, connect one of the positive terminals to the positive terminal of your amplifier, and one of the negative terminals to the negative terminal of your amplifier.
Make sure to use appropriate wiring and terminals that can handle the power output of your amplifier and the subwoofer. Also, make sure to secure all connections properly to prevent any loose connections that can cause electrical interference or damage to your audio system.
If you have multiple Alpine SWS 12D4 subwoofers, you can wire them in parallel to achieve a lower ohm load and increase the power handling of your audio system. However, make sure to calculate the total impedance of your subwoofers and amplifier to ensure compatibility and prevent any damage to your audio components.
Parallel Wiring – 8 ohm
If you want to wire your Alpine SWS 12D4 in parallel to achieve an 8 ohm load, you will need to connect the positive terminal of each voice coil to the positive terminal of your amplifier, and the negative terminal of each voice coil to the negative terminal of your amplifier.
This wiring option is suitable for amplifiers that can handle an 8 ohm load, and it will provide a lower power output compared to the 2 ohm option. However, it can still provide a decent performance for most audio systems.
Series Wiring – 8 ohm
If you want to wire your Alpine SWS 12D4 in series to achieve an 8 ohm load, you will need to connect the positive terminal of one voice coil to the negative terminal of the other voice coil, and then connect the remaining positive and negative terminals to your amplifier.
This wiring option will provide a higher impedance and lower power output compared to the parallel options, but it can be suitable for amplifiers that can handle an 8 ohm load and provide a cleaner sound output with less distortion.
Series Wiring – 16 ohm
If you want to wire your Alpine SWS 12D4 in series to achieve a 16 ohm load, you will need to connect the positive terminal of one voice coil to the negative terminal of the other voice coil, and then connect the remaining positive and negative terminals to your amplifier.
This wiring option will provide the highest impedance and lowest power output compared to the other options, but it can be suitable for amplifiers that can handle a 16 ohm load and provide a cleaner sound output with less distortion.
FAQ
What is the maximum power handling of the Alpine SWS 12D4?
The Alpine SWS 12D4 can handle up to 750 Watts RMS and 2250 Watts Peak.
Can I wire my Alpine SWS 12D4 to a 1 ohm load?
No, the Alpine SWS 12D4 is not designed to be wired to a 1 ohm load. Wiring it to a lower impedance than recommended can cause damage to the subwoofer and the amplifier.
Do I need to use a specific gauge of wire for my Alpine SWS 12D4?
It is recommended to use a wire gauge that can handle the power output of your amplifier and the subwoofer. Consult the manufacturer’s specifications to determine the appropriate wire gauge for your setup.
Can I use multiple Alpine SWS 12D4 subwoofers in my setup?
Yes, you can wire multiple Alpine SWS 12D4 subwoofers in parallel or series to achieve the desired impedance and power handling. However, make sure to calculate the total impedance of your subwoofers and amplifier to ensure compatibility and prevent any damage to your audio components.
Do I need to install a crossover with my Alpine SWS 12D4?
A crossover can help to filter out frequencies that the subwoofer is not designed to handle, and prevent damage to the subwoofer and the amplifier. It is recommended to install a crossover with your Alpine SWS 12D4 for optimal performance and longevity of your audio system.
In conclusion, the wiring diagram for the Alpine SWS 12D4 provides options for different ohm loads and power handling, and it is important to choose the appropriate option for your amplifier and audio system. By following the instructions and using appropriate wiring and terminals, you can achieve optimal performance from your Alpine SWS 12D4 subwoofer and enjoy high-quality sound output.
