[QUOTE="NSTALN, post: 8548227, member: 588169"] With dual voice-coil subs you can wire them (2) different ways, series and parallel. When running in series the resistance is added...(2) 4ohm coils wired in series will give you a final load of 8ohms. The same is true for (2) 2ohm coils...in series they will give you a final load of 4ohms. To wire coils in series is very easy...just take the + out of the amp and connect it to the + of sub 1, run a wire out of sub1 - to sub 2 +, then run wire out of sub 2 - back to the amp -. When running coils in parallel things are a bit different...I'll not bug you with the formula but when running (2) 4ohm coils parallel with yield a final load of 2ohms. When running (2) 2ohm coils parallel the final load will be 1ohm. So 2ohm dvc sub will allow you to run a single 4ohm load (series) or a single 1ohm load (parallel). A 4ohm dvc sub will allow you to run a single 8ohm load (series) or a single 2ohm load (parallel). [/QUOTE]
