Ive got 2 JLW3D2's running off a Pheonix Gold 900.1d and they run fine so im sure you will be ok:o | |

quote: cant u show 2ohm, with two 4ohm subs??? i have ordered the 4ohm ones now, and i have rang my local Music specilists(SMC)! they said that 2ohm and 4ohm subs would workwith that amp, but the 4ohm has more flexability, and would be a better option! | |

Keep the subs have as corb says 400 is plenty for these subs. | |

my amps stable at 1/2ohm in stereo and 1 ohm in mono, why is it different for mono and stereo? | |

so two dual 4 wired up in parallel shows 1ohm | |

As everyone has said, if you get the dual 4ohm coiled subs, you can then run the subs to show your amp a 1ohm load. BUT if you do that you'll be putting 600RMS into each sub. | |

cheers ppl!! i will ring the company up tomorrow, and c if they will excange them for the dual 4ohm!! that way i can b safe not blowing anything, and get more power out of my amp!! | |

yea but if u run the subs in serise instead of parelle(0.5ohm at amp) u get the ohm up 2 4 each sub than down 2 2 at the amp! | |

yea, but its basic physics and surely anyone that does anything with electronics/circuitry would know it ;) :lol: | |

quote: Huh? :boggle: 0.5ohms is far less than 1ohm and 1ohm is far less than 4 ohms etc etc Therefore 0.5 ohms isnt an "enormous amount of resistance", hence why amps can produce more power at lower ohm's because there is hardly any resistance! And if you run the amp at 0.5ohms, and thats if you lucky without it going bang, it would be producing around the 1.6Kw - 2Kw RMS! mark (a rough guess) and you subs like about 300w RMS...so i could see them going bang if you not lucky. Send them back mate and get the 4ohm version or send ya amp back and get something that will suit them :thumbs: | |

just been talking 2 andy on msm! i agree with ian but think his amp is plenty powerful enough 2 run then 2ohm! | |

Run them at 2 ohm, 1200w RMS is a bit much for these subs TBH, trust me ;) | |

The problem you'll have is the dual voice coil means each sub is effectively already a 1ohm load if both voice coils are wired in parallel. Parallel up another sub and you're looking at 0.5ohm loading, thats an enourmous amount of resistence which is too much for all but the most well built and well cooled amps. | |

what abt if i bought 2 4 ohm ones??? would that work?? | |

You could run it through a circuit. | |

here r two of my subs, they r dual 2 ohms, (JL-12W3V2D2) but i have just been told i cant run them good with this amp, or its hard to wire?? PLEASE can some1 tell me if i have bought the wrong ones?????? |
