There are multiple ways to wire dual voice coil (DVC) Pioneer subs in your stereo system. The configuration depends on how many subs you want to install, the amount of ohms the subs have, how many channels the amp has and how much resistance the system can handle. There are literally dozens of options for dual voice coil subs, but most commonly people have two 4-ohm subs that they are running from either a two-channel or one-channel amp at 4 ohms of resistance. Learn how to wire these subs for these two configurations.

Start with the left sub. Run the positive speaker wire from the left positive output on the amp to one of the positive speaker terminals on the left sub. Dual voice coil subs carry two sets of positive and negative terminals, one set for each voice coil. You can identify the positive and negative channels by a small "+" symbol next to the positive input and a "-" symbol next to the negative. The negative wire should have a white line running along the length of it or have the same symbol.
Splice another speaker wire onto the positive terminal where you ran the first wire and run it to the other positive terminal on the same sub. To splice the wire, insert the second wire into the same terminal in which you inserted the first wire. If the terminal isn't big enough, take the tip of the second wire and wrap it around the exposed section of the tip of the first wire to make a solid connection, but leave room to insert the first wire into the terminal. You may need to strip back the protective casing on the first wire to leave enough room.
Repeat this process for the negative speaker wire for the left sub. Run the wire from the left channel's negative output to the negative terminal. Splice another wire onto the wire at this connection point and run that wire to the other negative terminal on the same sub.
Move to the right sub and repeat the exact same steps in the same order but using the amp's right channel. Start with the positive wire and run it to the right sub's positive terminal, splice a wire on to the wire at the connection point and run it to the other positive terminal on the same sub. Repeat for the negative wire. Run the negative wire from the right channel to the negative terminal, and attach another speaker wire from that terminal to the other negative terminal on the same sub.
Run the positive speaker from the positive output of the amp to one of the left sub's positive speaker terminals. From this terminal, splice another speaker wire onto the first wire and run that wire to one of the positive terminals on the right sub.
Repeat the process with the negative wire. Run the wire from the amp to the negative terminal on the left sub, but make sure you are running this wire to the opposite voice coil you used for the positive wire. Splice another wire at this terminal and run it to the negative terminal on the right sub. Again, make sure it is not on the same voice coil you used with the positive wiring. You should now have an unused positive and negative terminal on each sub with each voice coil having one empty terminal.
Run a speaker wire from the unused positive terminal on the left sub to the unused negative terminal on the same sub. This wire does not come from the amp but only runs to within the same sub. Repeat the process for the right sub.
