[QUOTE="BnGRacing, post: 7461314, member: 557400"] 1366@1ohm. Let's pretend this rating is at 13.8v and see, mathematically, how much heat that thing gives off; 1366w = 13.8v * CURRENT * 65% amp efficiency 1366w/65% = 13.8v *current 2101/13.8 = current 152 = current So the amp ***** up around 150A. Input wattage would be 2100 and output wattage is 1366. You have lost 730+ watts of power to heat (and even more if voltage dips). To give you an example of how much energy that is, I did a google search for 800w heater and came up with this; [IMG]http://www.cef.co.uk/assets/images/medium/23342.jpg?1313976781[/IMG] At full tilt, your amp will give off enough heat to warm up a small basement. Not exactly what I'd use in a stealthy install if it's going to be covered. [/QUOTE]
