IA audio 20.1 wattage results

1) read closer...i answered that
2) well no shit! the amp isnt 100% efficient. lets look at the obvious:

wattage=amperage multiplied by voltage. secondly i dont see how running the amp for 5 seconds the first time, then having it shut off, and then ran for 5 more seconds is gonna make anything hot besides your gf.

i dont know if you ever used a micro vat or know what it is, but the numbers are there. now whether you wanna argue that, oh the amps efficiency is 75% so your not seeingthat power. now if you think you can do a better test, maybe bench test it yourself, then more power to ya, other than that, i dont care.

"terrible review" : holy shit this was suppose to be a review????

Wow, you're bad.

No, you didn't answer my question. You told me the DCR of the sub you had hooked up; that is NOT what load the amp is seeing. Do you know what impedance really is? It is not the same thing as DC resistance.

If you know the amp is not 100% efficient, why the hell would you measure the current draw? You can't assume that because the amp has a "rated" efficiency of 75% at 4 ohms that it will have the same at lower impedances. You are also taking this number as a constant and considering it to be spot on, which it is not, just like power ratings.

You obviously didn't understand what I was talking about with the heat comment. I was hinting at efficiency but you were too derka to realize it.

I could do a better test and I would measure both input and output current draw. That way I could get real power delivered and see how efficient the amp really is. I would love to, but I don't have the money or the equipment to do so.

Also, you set the gains using a -6dB tone and a scope and then tested with a 0dB tone? You do know that is pushing the amp into clipping correct? Do you understand why people use -6dB and -10dB tones to set their gains? I have a feeling you don't.
