New member Username: Tremor1127Post Number: 2 Registered: Aug-06 | it looks like it only shows 2 ohm speakers there too... ive seen a couple like that and even on crutchfield.com but nothing for two 1 ohm speakers... |

New member Username: Tremor1127Post Number: 3 Registered: Aug-06 | no, its a fuse on the basket (like on the boston acoustic g5 subwoofers, for sure) that is 4 ohm until you flip it and it becomes 1 ohm... the subwoofer is dvc but the switchable fuse leaves each with just 1 set of terminals... i need to know what load one 1ohm speaker ran to another 1ohm speaker is... |

New member Username: Tremor1127Post Number: 4 Registered: Aug-06 | it is dual voice coil and im not positive but i think it stays dvc either way the fuse is switched... the speakers will be ran with the fuse set on 1ohm and im wanting to get a 1000-1200x1 at 1ohm and run them with... i guess even if they draw a .5 ohm load the amp will just do 1ohm and i will still get max power, eh? |

New member Username: Tremor1127Post Number: 7 Registered: Aug-06 | see the way they are with the fuse i dont really know what impedence they will draw at all, since i have had them ive kinda thought both running at 4 ohm will give me a 2 ohm load on an amp, and both at 1 ohm will draw .5 from an amp, and i dont want that, id rather run at 2 ohms... |

Gold Member Username: RovinTrinidad & T... Post Number: 8844 Registered: Jul-05 | well simple rule is if u run 2 coils in parallel ohms drop to 1/2 ex a 4ohms dvc sub = 2ohms if u run a dvc into series ohms doubles ex a 4ohms dvc sub = 8ohms so now see if u can figure it out .....  |

New member Username: Tremor1127Post Number: 8 Registered: Aug-06 | i kinda knew all that, my deal is these subs have the fuse... so if i run them one to another (positive from amp to one sub to the next, same with negative) with both set on 4 ohm it should be a 2 ohm load on the amp then i believe... |

Gold Member Username: IlluminatorUSA Post Number: 4142 Registered: Apr-05 | The fuse just wires them in parallel or series, they're still DVC 2 ohm speakers. Look at the diagrams for (2) DVC 2 ohm speakers and those are your options: http://www.the12volt.com/caraudio/woofer_configurations.asp |

New member Username: Tremor1127Post Number: 9 Registered: Aug-06 | damn, ok, i see now... ive been looking for dvc 1 ohm, but they are 1 ohm only because its dual 2 ohm voice coils... its still confusing as far as only being one set of terminals, how can i find out how to wire selectable ohm subwoofers? |

New member Username: Tremor1127Post Number: 10 Registered: Aug-06 | oh i didnt see marks post, i will probably do that for a 2 ohm load, but how can i run these in series? |
