New member Username: Thump4863Post Number: 1 Registered: May-05 | just got a rockford fosgate punch stage 2 8" sub to replace the crappy sub that came from the factory. I already have an Infinity Kappa 102a sub that used to power 2 10" Orion DVCs pretty good. My question is how should I wire my amp up to push the single 8" sub. Here are the specs. Sub 4 ohm 200RMS 300 Peak Amp 2 X 100Watts 4 ohm 2 X 150 2 ohms Bridged 300W 4 ohm Thanks for your help. |

illusionstudios Unregistered guest | seth - u can actually run morepower thru sub then its rated at distortion blows voice coils - in your setup you will be ok your ears will tell you when sub is reaching its limits unless its in trunk then u cant hear the distortion as well in this case open trunk and listen then look to ee how high your volume is on deck |

I'm going to get some silicone and seal it up better. Thanks a lot. |

Bronze Member Username: Mikechec9Chicago/atlanta Post Number: 72 Registered: May-05 | it is a single 4ohm sub. his options are either 2ohm or 8ohms. bridging it 4ohms isnt an option. |

New member Username: Thump4863Post Number: 4 Registered: May-05 | Mike, why do you say it has to be either 2 ohm or 8ohm. Just curious. Thanks. |

Bronze Member Username: Mikechec9Chicago/atlanta Post Number: 74 Registered: May-05 | if your sub were a 2ohm dvc you would be all good with just one sub and that amp. you might still be good if it is stable bridging at 2ohms. http://www.jlaudio.com/tutorials/wiring/#2dvcsp |
