Post Number: 2452 Registered: Dec-06 | "BTW is you're talking about the massive, those amps are overrated so no that one won't do 3000w." well if i set the gain so ac voltage come out at 77volts tecnicaly wouldnt that mean it puts out the 3000rms cuz that what the gain would be set to? |

Gold Member Username: Nd4spd18Philadelphia, PA Post Number: 8661 Registered: Jul-06 | Hell no. Thats how you get clipping, setting the gain to try and make the amp do more power than it actually can. Think about it can you crank the gain way up and have the amp do 4000w just because you set it to that voltage? No. |

Gold Member Username: Nd4spd18Philadelphia, PA Post Number: 8666 Registered: Jul-06 | IIRC that amp does around 2500w but don't quote me on that |

Gold Member Username: Snarl2004Digital Design 9515, Massive Audi... Post Number: 2454 Registered: Dec-06 | well i think im buying a zx2500.1 tonight if everything goes right i was jsut curious about the massive. you can use a clamp meter and a dmm to find out an amps output rms right? |

Gold Member Username: Nd4spd18Philadelphia, PA Post Number: 8668 Registered: Jul-06 | Noooo.... takes a lot more than that... power supply that will hold voltage under full load scope high current resistors of the resistance you want to test DMM then in addition to that if you want to measure efficiency you need a clamp meter. |
