Is it possible to wire single and dual voice coil subs together?

How to Wire Two Dual-Voice Coil Subs to a Single-Channel Amp

• Answer:

  Dual-voice coil subwoofers have two sets of positive and negative speaker wire terminals instead of one. You can wire two dual-voice coil subs to a single-channel amplifier at a 4-ohm load or a 1-ohm load. Ohms refer to the amount of resistance you are placing on the amp. The lower the ohms, the more decibels. However, you must ensure your amp is stable at 1 ohm, or you can destroy the amp if wired for that resistance. Difficulty: Moderately Easy Instructions Wiring Two Dual-Voice Coil Subs to Produce a 1-Ohm Load Run the positive speaker wire from the positive speaker output of the amp to one of the positive terminals on the first sub. From this connection point, splice another speaker wire onto this wire at the point of connection on the sub and run it to the positive speaker terminal on the same sub. Repeat the process for the second sub. You will need to run two speaker wires out of the positive terminal, which could get crowded. Use a thinner wire if necessary. Run that wire to the positive terminal on the second sub, splice it at the point of connection and run it to the positive terminal on the same sub. Run the negative speaker wire to the subs using the same steps performed for the positive speaker wire. The first wire goes from the negative output to the negative terminal on the first sub, the wire is spliced and run to the second negative terminal on the same sub. The process is repeated for the second sub. Wiring Two Dual-Voice Coil Subs to Produce a 4-Ohm Load Run the positive speaker wire from the positive speaker output of the amp to one of the positive terminals on the first sub. From this connection point, splice another speaker wire onto the first sub's positive terminal and run that wire to a positive terminal on the second sub. Repeat the process for the second sub with the negative wire. Run the wire from the amp's negative output to a negative terminal on the first sub, splice another wire on and run it to the negative terminal on the second sub. Run a speaker wire from the unused negative terminal to the unused positive terminal on each sub. This wire does not originate from the amp--it only runs from one terminal to the other. The wire also doesn't go from one sub to the other--only within the same sub.
