You are very mistaken in that thought. Just because you are wired to 1 ohm nominal at the amp doesnt mean you are actually seeing 1 ohm once signal is applied to the subs. Do some research and find out about impedance rise and you will understand what I am talking about better.
I know about box rise, which is unavoidable. But nobody buys an amp knowing their box will rise to "X" ohms and tries to get "X" watts at that impedance. People buy based on the power rating of their subs and want to assure that if they have 4 subs with 1250 rms handling each wired into a 1 ohm load that their 5k amp will deliver at least 5k at 1 ohm.
Maybe I'm wrong and other people want to know the 2 and 4 ohm performance. I'd want to know 2 ohm on Rockford amps where 2 ohms is the lowest stable impedance and where the amp makes it's rated power. But on a 1 ohm stable amp I couldn't care less what the 2 and 4 ohm performance is. I would like to know if it handles .8 and .67 without going into protect and what power it makes at those impedances.
Yes the amps will see higher impedances, but that's irrelevant to me. But that's just me. If you want to do all the tests and share all the numbers that is way cool, I'm glad you are doing it. I just figured 1 ohm and below is what most people want to see. And I didn't mean "a 12k never runs at 4 ohms". I meant, "nobody wires a 12k to a 4 ohm load".
Anyway, thanks again for doing this. I'd love to see my crossfire cfa-1000d on the ad-1. I've burped it at .25ohms on 4 kicker 12L7's!
