I have 2 degrees in electronics, one for basic electronics & repair and the the other for electronics engineer. I have designed 2 car amps both class D one 2200 watts @ 1 ohm and the other 1100 watts @ 1 ohm both RMS. I have tested them both and they put out a quite bit more. Also I own a small amp repair business along with installs. That's about it for this site.
