Would 400 RMS Be Too Much?
|
Silver Member Username: KaerfplSpencerport, NY USA Post Number: 122 Registered: Jun-06 | Hey, Ive got a sub that im trying to find an amp for. It has a 250 Watt RMS rating and it has a 4 Ohm dual voice coil. Would putting 400 Watts into this sub not be a good idea or will it still perform fine? If it's not a good idea, then what amp or RMS range should I be looking for? |

Silver Member Username: KaerfplSpencerport, NY USA Post Number: 126 Registered: Jun-06 | ok, cool, but what if I wanted to get a 2-channel amp for this? Since this sub has a dual voice coil, how much RMS would I be getting out of an amp that would be 200x1 @4Ohms or even 400x1 @4Ohms? Would that be overdoing it or no... |

Gold Member Username: Dustin3Tigard, Or U.S. Post Number: 2197 Registered: Oct-05 | overdoin it would be 500 into a 250 rms sub because your overpowerin it 50%. thats when you shouldnt do it. he only givin 150 more... not much at all. yes, some subs cant take it but if you keep ur gain down just a lil bit, you can turn the volume up pretty good without the chance of clippin ur sub (which wont happen overpowerin it by 150 watts.) wut sub do u have? |

|
Silver Member Username: KaerfplSpencerport, NY USA Post Number: 129 Registered: Jun-06 | well since its a DVC and both of them are wired, wouldnt it be 2Ohm? |

Gold Member Username: JuliobSanto DomingoDominican Re... Post Number: 1202 Registered: Dec-05 | depends on the brand, if the sub is an infinity, i would play carefully, plus the new amps don't put their power at 12V you can wire it to get 400w rms if you want. Bassman what's up bro! |

|
Gold Member Username: Dustin3Tigard, Or U.S. Post Number: 2213 Registered: Oct-05 | joe, so yes, since its DVC 4 ohm sub, you need an amp that does 250-350 @ 2 ohms. |
|
Gold Member Username: Dustin3Tigard, Or U.S. Post Number: 2214 Registered: Oct-05 | the alpine would be fine |
|
Silver Member Username: KaerfplSpencerport, NY USA Post Number: 134 Registered: Jun-06 | Ya, the Alpine would be nice Also that Kicker is 250 @4Ohm, so what would it be giving out to my MA since its 2Ohm? Or am I supposed to take off one of the wires to the other VC and make it 4Ohm? Sorry if my questions are stupid, I just make to be 100% sure on what im doing when I buy an amp. |

Gold Member Username: JuliobSanto DomingoDominican Re... Post Number: 1240 Registered: Dec-05 | go with alpine and no, don't wire one coil. that was a suggestion if you had dual 2 sub, but you have dual 4, go with alpine. you'll be happy |

Gold Member Username: Dustin3Tigard, Or U.S. Post Number: 2246 Registered: Oct-05 | yea. the kicker wouldnt work because you can wire a DVC 4 ohm sub to 4 ohms (where the kicker amp does 250 watts) "so what would it be giving out to my MA since its 2Ohm" i guess i dont understand wut ur sayin. i thought u had a DVC 4 ohm sub --- you can only wire subs to a certain ohm. and a DVC 4 ohm sub (one of them) can only wire to a 2 or 8 ohm load ^^ because ur sub is 250 rms, and can be wired to a 2 or 8 ohm load, you want an amp that does 250 + @ 2 ohms because thats how you wire a DVC 4 ohm sub. on the other hand if you had a DVC 2 ohm subs, you would needs an amp that does 250 + at 1 or 4 ohms. because (1) DVC 2 ohm sub = 1 or 4 ohm load. go the www.the12volt.com --- then woofer wiring on the left and experiment -- it will give you a diagram on how to wire it to "Or am I supposed to take off one of the wires to the other VC and make it 4Ohm" it doesnt have any wires on it if you havent hooked it up yet |
