Silver Member Username: TdbdadrummerPost Number: 923 Registered: Aug-05 | You'll probably get some of the rated wattage, but they'll be driven into clipping easily. If you're on that type of budget (like myself) look into Audiobahn amps. Specifically the Audiobahn Intake Series amps. They have several useful models which can be had for $150 or less on E-Bay, brand new! Guaranteed to put out power they are rated in RMS, and they seem to handle long periods of brutality as well, just keep vented so the fan can circulate some air. |

Silver Member Username: N2audioLawrence, Ks USA Post Number: 280 Registered: Mar-04 | PA's class D's are very powerful, but not what's stated. The A/B's - hard to say really, you don't see a lot of legit power tests done on them, but the one I messed with was the OV4-800 which was rated at 85x4 and it was definitely in the ballpark. 75% would be a conservative estimation IMO. FWIW - if you're looking for some power on a budget www.profilecaraudio.com is almost GIVING away refurbs. The CA600 for example is about $75 shipped and is ~400 real watts. |

Silver Member Username: N2audioLawrence, Ks USA Post Number: 287 Registered: Mar-04 | the A3000DB should be around 2KW at 1 ohm ~14v. test reports range between 1800 and 2300. |

|
Silver Member Username: N2audioLawrence, Ks USA Post Number: 289 Registered: Mar-04 | well, that's the range, besides the difference between the two would be nearly inaudible. |

Silver Member Username: N2audioLawrence, Ks USA Post Number: 305 Registered: Mar-04 | Jake - in a perfect world - doubling power nets a 3 db gain - 500w = 28% of 1800 = <1dB gain, and being that it's NOT a perfect world - it would be even less than that. |

Gold Member Username: Kd7nfrMontpelier, ID United States Post Number: 1372 Registered: Apr-05 | Ok... argue if you want. But messing with Eclipse Ti's in my friend's car, 500 watts made a hell of a difference... |
|
Silver Member Username: N2audioLawrence, Ks USA Post Number: 313 Registered: Mar-04 | going from 500 to 1000 is a BIG difference, from 1800 to 2300 -- not so much.

Silver Member Username: FandimReno, Nevada United State... Post Number: 581 Registered: Jun-05 | Find out if they're factory refurbished, or refurbished by the retailer. That makes a big difference. If it's factory refurbished, chances are, it's a new amp with an old case.. It's less costly to put in entirely new insides, than paying an employee an hourly rate to open up the amp, find out what's wrong, and repair it. |

Silver Member Username: FandimReno, Nevada United State... Post Number: 582 Registered: Jun-05 | Also, saying the difference between 1800 and 2300 watts is inaudible is a joke. The whole thing about being able to not tell the difference when it's less than one dB.. well, the thing is - dB's grow exponentiallly.. I.E. 80 dB is twice as loud (roughly) as 70 dB... So the difference beteween say, 150, and 151 dB, is a LOT greater, than the difference between 85, and 86 dB. |
|
Silver Member Username: N2audioLawrence, Ks USA Post Number: 335 Registered: Mar-04 | wrong |
|
Silver Member Username: N2audioLawrence, Ks USA Post Number: 336 Registered: Mar-04 | it's exponentially harder to get from 150-151, the difference in sound is exactly the same. |
|
Silver Member Username: Matt12490Benicia, California Post Number: 288 Registered: May-05 | Ok so has anyone bought refurbished amps off their site?? If so any feedback? especially on the directed audio amps. |

The decibel scale, like our hearing, is logarithmic. To our ears, a 1db gain is 1db gain regardless of what the reference level is, 151 over 150 is no more substantial than 21 over 20. 1800 watts and 2300 watts isn't a substantial difference. It may impress somebody, but you aren't going to notice a lot of difference when you're adding 500W to what is already a very high level of power. |

Silver Member Username: LbecknerTulsa, Ok Usa Post Number: 502 Registered: Oct-04 | I agree with jonathan. I went from 1500 watts to 2500 watts and could tell little difference. I think that if you double your power you only gain like 3db right? So by adding 1000 watts I only gained 2db right? |

Gold Member Username: Jonathan_fGA USA Post Number: 5480 Registered: May-04 | Double power is 3db increase 4x power is 6db increase Doubling percieved volume requires 10x the power and is a 10db increase. |
