I have a Rockford T2000.1bd in my car with stock electrical, except for the big 3. I have the amp hooked up to two 12 inch Alpine Typr R's @ 1ohm at the moment. The amp is not turned up much at all, maybe 15% gain with 2volt preouts on HU, with no bass boost. With deeper bass, sometimes the volts will drop to 11. I was just wondering if this is low enough to damage the amp? If not, what is the ''danger point?''
