I'm pretty sure the 8105D does do rated. I've tuned it to 34.64 volts when the head unit is on 30/50 and it does 300wrms at 4ohms all day long without any clipping or the amp even getting warm. Today I played 0db recorded bass heavy tracks on my way to work, a 20-25min drive. Non stop bass for 11miles. Pop the trunk in the parking lot and felt the amp, not even close to being warm.If it did, then ill zip my lip but I doubt they do.
