New member Username: EraymondPost Number: 5 Registered: Jun-10 | what if i rand the 4ohm sub and the 4ohm load amp and didnt bridge it then what the ohms be? |

Silver Member Username: SkdooleyRoanoke, VA Usa Post Number: 798 Registered: Oct-09 | If you run it at an 8 ohm load, whatever the amp is rated at doing X 1 channel at 4 ohm, divide that rms in half. Set the gain accordingly. |

New member Username: EraymondPost Number: 6 Registered: Jun-10 | would it be better to run it a 8 ohm or 2 ohm? |

New member Username: EraymondPost Number: 7 Registered: Jun-10 | do i bridge it if i want to go to 2 or 8 ohms? |

Silver Member Username: SkdooleyRoanoke, VA Usa Post Number: 803 Registered: Oct-09 | If youre running a single sub, bridged is the only way to run it, unless you are running it on just one channel. If you run it bridged you have to stay at 4 ohm or 8 ohm, it cant run at 2 ohm. If you run it at 2 ohm, the amp is going to produce a clipped signal and get really hot. That over time will damage your amp and/or sub. Depends on how much clipping and how well each item is built. |

Gold Member Username: IlluminatorUSA Post Number: 5203 Registered: Apr-05 | Yep, just like Shawn said, you can only run that configuration at 8 ohms, 2 ohms is going to damage that amp, and given that it's a Sony Xplode, a 2 ohm load will fry it pretty quickly. Also, these are some really basic questions that the OP is asking. While I'm fine with people getting into car audio, there are some things which are better learned by doing a bit of research than just adding another thread here in the forum, and it's way nice of Shawn to be really patient and answer the OPs questions. So just to set the OP in a good direction for hooking up subs, here's the site Shawn used earlier to calculate ohm load on the amp: http://www.rockfordfosgate.com/rftech/woofer_wizard.asp# |
