When wiring a single voice coil Polk Audio DB1242DVC subwoofer, there are a few different options depending on the desired impedance load. Here is a wiring diagram and an explanation of each option:
- Single 4 Ohm Load: If your amplifier is rated to handle a 2 Ohm load, you can wire the subwoofer in parallel to present a 2 Ohm load. This can be done by connecting the positive terminal of the subwoofer to the positive terminal of the amplifier, and the negative terminal of the subwoofer to the negative terminal of the amplifier.
- Dual 4 Ohm Load: If your amplifier is rated to handle a 2 Ohm load, you can wire the dual voice coils of the subwoofer in parallel to present a 2 Ohm load. This can be done by connecting the positive terminals of both voice coils together, and then connecting the negative terminals of both voice coils together. The positive terminal of one voice coil should be connected to the positive terminal of the amplifier, and the negative terminal of the other voice coil should be connected to the negative terminal of the amplifier.
- Dual 4 Ohm Load (Series Wiring): If your amplifier is rated to handle an 8 Ohm load, you can wire the dual voice coils of the subwoofer in series to present an 8 Ohm load. This can be done by connecting the positive terminal of one voice coil to the positive terminal of the other voice coil, and then connecting the negative terminal of one voice coil to the negative terminal of the other voice coil. The positive terminal of one voice coil should be connected to the positive terminal of the amplifier, and the negative terminal of the other voice coil should be connected to the negative terminal of the amplifier.
- Dual 4 Ohm Load (Series/Parallel Wiring): If your amplifier is rated to handle a 4 Ohm load, you can wire two dual voice coil subwoofers in series and then wire them in parallel to present a 4 Ohm load. This can be done by connecting the positive terminals of both subwoofers together, and then connecting the negative terminals of both subwoofers together. The positive terminal of one subwoofer should be connected to the positive terminal of the amplifier, and the negative terminal of the other subwoofer should be connected to the negative terminal of the amplifier.
It is important to note that wiring the subwoofer to a load lower than what your amplifier is rated for can cause damage to the amplifier. Make sure to check the specifications of your amplifier and ensure that it can handle the specified load. If you are unsure or have any questions, it is recommended to consult with a professional or contact Polk Customer Service for assistance.
