New member Username: Kirbdog22Post Number: 1 Registered: Nov-05 | I am a illiterate when it comes to car audio first of all. I would like to know if I was going to purchase the subwoofer listed above if the anp that should go with it would be one that could run 1000W RMS @ 2 ohm? What type of gauge wiring would I need and recommended box? |

Gold Member Username: AraknidBOCA , FL U.S. Post Number: 1196 Registered: Nov-04 | The sub is 1000 watts RMS so you would need an amp that puts out 1000 watts RMS at 1 ohm or 4 ohm. |

New member Username: Kirbdog22Post Number: 3 Registered: Nov-05 | Why not just get one that runs at 1000W at 2 ohms? |

And 1.5 cubic feet for a ported box. http://www.speedsound.com/caraudio.asp?pg=products&specific=jngmgqnoo doesnt say anything about sealed but im guessing around 1.1 cubic feet. |

New member Username: Kirbdog22Post Number: 5 Registered: Nov-05 | Alright i understand, but why would they (Rockford) say impedeance 2 ohms i just don't get it, i look online to find and amp that matches up with that. |

Gold Member Username: AraknidBOCA , FL U.S. Post Number: 1199 Registered: Nov-04 | ok check it out. DVC means dual voice coil. Each coil has a impendance of 2 ohms for your sub. In series the impendances of the coils are added together so series would be 4 ohm. In parallel the impendance becomes half of one of the coils. So in parallel it would be 1 ohm. |

Silver Member Username: CenusHicksville, Ohio Usa Post Number: 678 Registered: Jan-05 | a dvc 2ohm sub means each voice coil is 2ohms so when wired in parrell it makes a 1ohm load and when wired in series it makes a 4ohm load. and 2 good amps to power that sub would be kicker kx1200.1 or RE 12.1 |

Gold Member Username: AraknidBOCA , FL U.S. Post Number: 1200 Registered: Nov-04 | This is helpful http://www.rockfordfosgate.com/rftech/wiringwizard.asp Just imput the info. In your case 1 sub and DVC 2 ohm and it will show you diagrams of the possible ways to wire it. |

New member Username: Kirbdog22New Bern, North Carolina USA Post Number: 8 Registered: Nov-05 | So which amp would you select one that pushes 1000W @ 4 ohms or one that pushes 1000W @ 1 ohm? |
|
Silver Member Username: CenusHicksville, Ohio Usa Post Number: 680 Registered: Jan-05 | how much do u want to spend, the RE 12.1 sells for 390 shipped, which would make a perfect amp for that sub. |
|
Gold Member Username: AraknidBOCA , FL U.S. Post Number: 1201 Registered: Nov-04 | It would be much cheaper to get the amp to run for 1 ohm. |
|
New member Username: Kirbdog22New Bern, North Carolina USA Post Number: 9 Registered: Nov-05 | what is the RE 12.1? any others besides that? |
|
New member Username: Kirbdog22New Bern, North Carolina USA Post Number: 10 Registered: Nov-05 | If i get and amp that runs at 1 ohm doen't that kind of put some stress on the amp? |
|
Gold Member Username: AraknidBOCA , FL U.S. Post Number: 1202 Registered: Nov-04 | No it will say on the specs if it is 1 ohm stable or not. If it is then thats what it was designed for. |
|
Bronze Member Username: Kirbdog22New Bern, North Carolina USA Post Number: 11 Registered: Nov-05 | So look for and amp that can run at 1000W @ 1 ohm stable. |
|
Gold Member Username: AraknidBOCA , FL U.S. Post Number: 1203 Registered: Nov-04 | Yup. Your getting one sub right? |
|
Silver Member Username: CenusHicksville, Ohio Usa Post Number: 682 Registered: Jan-05 | http://www.reaudio.com/html/amps.htm thats the RE 12.1, kx1200.1,sx1250.1, |
