The parallel config only works with two subs, if its one sub then parrallel is the same as a series, but i bet you know that already but just puttin it out there. |

Post Number: 1651 Registered: Dec-06 | "if its one sub then parrallel is the same as a series" what the he!! are you talking about. parallel is then all positves are together and all negitives are together. series is when you hook negitve to positive on your sub. You can have one sub and have it wired in parellel or series. You can have 2 subs and have them wired in parallel or series. http://rockfordfosgate.com/rftech/woofer_wizard.asp?submitted=true&woofer_qty=1& woofer_imp=3 the first example there is wired in parallel and the second example is wired in series. im assuming you have a DVC2 ohm sub so it needs to be wired like the first option. |

Bronze Member Username: Noob101Taylorsville, Utah USA Post Number: 90 Registered: Jul-07 | yes it is a dvc2 ohm sub and it's wired like option 1 except both wires coming from the amp are on the same side then linked over does this make and difference? Also could it be a problem to where i have the speaker wire connected in the amp? I put the wires where the guy i bought it from had the ends of his old wire sticking out... here's a pic to help explain.

Bronze Member Username: Noob101Taylorsville, Utah USA Post Number: 91 Registered: Jul-07 | also what should i have all the adjustable settings on the side set too or how would i know where to set them? options(phase,gain,db boost,low pass,subsonic,) I'll be buying a aftermarket head unit soon but i was recently in an accident and need about 625$ so it won't be for a while... also accident has nothing to do with the sub it was like this for about 2 weeks before that. |

Bronze Member Username: Noob101Taylorsville, Utah USA Post Number: 92 Registered: Jul-07 | i don't have the manuel as i bought it used and didn't receive it with it. i know it's stable at 1 ohm but say it is bridged can i just play with the wiring and see if anything helps or would this be a bad idea cause i could damage the sub if i hooked it up wrong? |

Gold Member Username: Joebruce15 AQ HD3 Post Number: 1397 Registered: May-04 | go to EDs website and download the manual. i know that amp is 1ohm stable, i just meant it might only be stable at 2ohms on each input. so if u have 2 2ohm loads,one in each input,then on the inside of the amp it will take the 2 2ohm loads and make it a final load of 1ohm. sorry if that doesnt make since,thats the best i can explain it. |

Bronze Member Username: Noob101Taylorsville, Utah USA Post Number: 93 Registered: Jul-07 | I understand. I'm buying a digital multimeter tomorrow so i can figure out how much power I'm putting into it and get my gains set right and hopefully this will fix the problem. |
