The reason manufacturers provide so many different "Coil Configurations"(Otherwise known as different Impedances, eg. Dual 4 ohm, Single 2 ohm, etc.) is to provide the consumer with different wiring options. Some examples: 1 Subwoofer -- Dual 4 ohm -- Wired in Parallel = 2 Ohm 1 Subwoofer -- Dual 2 ohm -- Wired in Parallel = 1 Ohm 1 Subwoofer -- Dual 4 ohm -- Wired in Series = 8 Ohm 1 Subwoofer -- Dual 2 ohm -- Wired in Series = 4 Ohm A lower "Impedance" results in more power, because there is less resistance. Think of each Coil as another subwoofer. I may have just confused you, but if you would like to learn damn well everything there is to know about car audio, visit bcae1 |

Typically, you would get Dual 4 ohm and wire them in parallel to achieve a 1 ohm load, where most amps are stable and will give you the most power. Although, there are a handful of amplifiers that have proven to be safe at .5 ohm, and will give you a lot of power(given that you have a decent charging system). In this case, you would get Dual 2 ohm subs. |

NO! *end rant* Dual 4 ohm wired in parallel = 2 ohms total Dual 2 ohm wired in parallel = 1 ohm total Use this site to determine what ohm load different subs can be wired to: http://www.rockfordfosgate.com/rftech/woofer_wizard.asp |

Silver Member Username: SkiesCourtenay, British Colu... Canada Post Number: 544 Registered: Aug-05 | ^^ He's getting TWO subwoofers, Dual 4 ohm in parallel would be 1 ohm total. If it were 1 subwoofer, you would be correct  |
