Unregistered guest | Ok, I recently bought the fosgate P5002 amp and 2 Fosgate Stage 2 200W RMS, 400W peak subs... the amp is rated at 125x2RMS@4ohms and 250x2RMS@2ohms... my question is... would it be safe to run the subs at 2 ohms with 250W RMS going to each sub when the RMS of the subs is 200... or would it be dangerous... thanks. |
Unregistered guest | also, say I do bridge the amp... since I have 2 subs... how would I connect them to the amp without making it 2ohm bridged, which would mess up the amp... if I wire them in parallel I'll only be able to wire them to either the left or right channel... yet if I bridge them and connect them in mono I'll have 500Wx1 @ 2ohms which the amp isnt made for... since it'll be both parallel and bridged at the same time... Anyone have any ideas as to how I would wire my subs to get 250W to each speaker or perhaps a mono bridged diagram that would keep the amp at 4 ohms will still connecting both subs Appreciate it |
ThatGuyYouKnow Unregistered guest | Your amp is Bridgable so do it. you will get 500w X 1 @ 2ohms and you wire your subs to 2ohms. this IS your amp isnt it? http://www.dealtime.com/xPF-Rockford_Fosgate_Rockford_Fosgate_Punch_P5002_125W_x _2_Car_Amplifier_2_channel_Amps |

Each sub will git 250 watt's at 2 ohm's. Bridged, each will git 250 at 2 ohm's. This will only work if your sub's are 4 ohm dvc I think. |
ThatGuyYouKnow Unregistered guest | hes subs are 4ohm Single VC. so you know. he HAS to do what i said. or hes feeding each 125wRMS @ 4ohms |
ThatGuyYouKnow Unregistered guest | Bridge the amp first then wire subs like this... http://www.rockfordfosgate.com/rftech/wiringwizard/2_4ohmSVC_2ohm.gif and youll be set. lets get this straight. Amp: Punch P5002 2xSub: Punch Stage 2 12" if those are correct than no problems. |

Unregistered guest | umm... my amp is only stable @ 4 ohms bridged... not 2 ohms... thats the problem and if I wire them in parallel without bridging... I'll get 2x250 @ 2 ohms... but I'll have to use either the left or right channel... which wont work either... cause my amp is 2 chan if I bridge my amp... thats makin my amp 500x1 @ 4 ohms... thats fine right there for 1 sub... but if you add 2 subs that'll drop it down to 2 ohms and burn the amp out... thats my issue. =\ |
ThatGuyYouKnow Unregistered guest | Bizrate had false information. sorry they supplied the info about bridging the amp down to 2ohms I should have checked RF. I was wrong. 125 W x 2 @ 4 Ohms RMS 250 W x 2 @ 2 Ohms RMS 500 W x 1 @ 4 Ohms Bridged RMS thats what ur birthsheet says i bet. |
Unregistered guest | yeah... now I Just gotta figure out how to set them up while keeping the amp stable... any ideas? |
ThatGuyYouKnow Unregistered guest | 1 sub per channel. all you can do. |
Unregistered guest | hmm... how would I wire them in parallel to get the 250 W x 2 @ 2 Ohms RMS though... because there would only be 1 set of +/- wires after its wired in parallel... it would have to go to either the left or right channels... which would eliminate the purpose of going with parallel |
ThatGuyYouKnow Unregistered guest | 1 sub per channel is. 1 is the left and one is the right. It is a 2 chan right? not that hard. You cant get 250w RMS X 2 with only Single Voice Coils. http://www.rockfordfosgate.com/rftech/wiringwizard/2_4ohmSVC_2ohm.gif ^1 channel and you get 250wRMS |
Unregistered guest | umm... thats how I have it wired right now... each sub is 4 ohms... the amp puts out 125x2 @ 4 ohms... I want to give them 250x2 @ 2 ohms... which the subs can handle... question is... how... since its a 2 channel amp... understand? |
Unregistered guest | what im saying is... the way i have it now... I have a left and a right pair of +/- coming out of my subs... since its @ 4 ohms... once its run in parallel I'll only have 1 pair of +/- coming out of the subs since they'll be wired together... thus I'll be forced to wire them either to the left or right channel of my 2 channel amp, defeating the purpose... hope that explains my situation a bit more... any ideas? |
ThatGuyYouKnow Unregistered guest | you cant get 250x2 no matter what you do. unless you just use one channel. PERIOD. Do research before purchase's. dont let sales men tell you whats gunna "rock". |
