The reason two is better than one is due to the fact that with DVC, there are more wiring options than a single voice coil speaker. Take for instance the sub you're looking at. You could wire that in parallel at 2ohms, or in series at 8ohms. With the single voice coil, you can only run at the speakers ohm rating. In regards to just hooking up a single VC, that would not be wise, and could be of detrement to your sub from what I understand, but you would need to speak to the more knowledgable members on this forum for a concrete answer. Regarding what to run your particular sub at, you would definitely want to run it at 2 ohms as long as your amp is stable down to two ohms, and that your sub can handle the wattage the amp puts out at 2 ohms. Why run the sub at 8ohms when it is capable of 2, thereby only getting one quarter of what your amp is capable of running? Like I said, you want to run the sub at the highest possible wattage it is capable of handling, providing of course you want the performance you've paid for. ;) |

Bronze Member Username: IronslavePost Number: 58 Registered: Sep-05 | i was just curious.. i havent used a DVC before but i read somewhere you could wire up a 4 Ohm DVC to run at 4 Ohms by using stereo... one chanel into each voice coil.. i have a 2 channel amp that can run 2 chanell's in Mono... would that be an option... sounds like a stupid idea to me though |

Platinum Member Username: GlasswolfWisteria, Lane USA Post Number: 11238 Registered: Dec-03 | sure with a two channel amp you can run one channel to each coil. that works, too. same result as bridging the amp, and wiring coils in series. same power. |
