Does anyone know actual factory output of a 1999 USAmps HC-50?

Or can find it online, I am not real computer savvy.

I need to know actaul FACTORY output so that I can figure in my 10-15% from mod kit installed by authorized repair tech. I am in the process of choosing new subs.

Please list values from 4 down to .25 ohm in mono config.

Thank you

Thats a nice page, but it is for the 2000 and up HC-50. It is a weaker form of the amp, with the larger knobs and the plexi bottom. I am getting at least 600 rms at 1 ohm now, need a test tone CD for actual volts, tho.

Edit: and i need info for .5 and .25 ohm as well sir....

Psycho, that was a very informative page that brought back memories, but unfortunately, it is for the 2000+ USAmps. The 1999 and earlier did not have a bass knob, boost or external gain adjustment knob. My amp will pop 50 amp fuses within 10 secs on test notes when wired at 1 ohm, so I dont know about actual power output. My amplifier was heated up by a factory tech to be +10-15% over factory, so that adds a small amount of juice.

I do know that at 1 ohm, it will push 2 L7 12's nearly to max excursion without distortion.

Maybe yours is a rare bird?

Thank you for your time looking, but I have another source.

The old guy that sold me that amp back in the spring of 2000 told me he has his old notebook of voltage out. That should help some, let's pray for 50+volts at 1 ohm //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
