How do I get 8 ohms out of a 4 ohm speaker

Quick load

  1. 8 ohm + 8 ohm = 4 ohm final (parallel connection)
  2. 8 ohm + 8 ohm = 16 ohm (series connection)

Single Voice-coil Subwoofers cannot change impedance unless they are combined with another subwoofer, in this case you would need another Single Voice Coil (SVC) of the exact type. By paralleling the two voice-coils, you would create a 4 ohm load if you started with two 8 ohm subwoofers. If you started with two 4 ohm subwoofers this would create a 2 ohm load.

Parallel load wiring:

  1. Positive of one woofer connects to the positive of the other subwoofer.
  2. Negative of one woofer connects to the negative of the other subwoofer.
