Determining exact power being sent to your speaker


How does one go about determining the exact amount of power being delivered by the amplifier to the speakers? Let's say the amp delivers 160w/channel at 4ohms (or so the reading materials state anyway) but yet the speaker specs show 120w maximum. My current integrated amp shows the volume
attenuation (dB units) in .5db steps ranging from -100 (min) up to 0.0 (max).

All that said, the concern is when should I be concerned about pushing too much power to the speakers and how I can determine the "Don't turn it up past this number on the display or you will damage the speakers..."

Your prickly defensiveness is entirely unwarranted. 

As I made no accusations, assertions or assumptions, I find it quite puzzling that you would describe my QUESTION as "putting words in [your] mouth".

All I have to say on this topic...

"I happen to be in the camp that is more concerned about the sound quality of an amp rather than whether it has a zillion watts"

Just curious -- are you suggesting these two factors are mutually exclusive? 

I happen to enjoy both aspects of my Hegel H390. My speakers have never sounded as good as they do with Hegel (250 watts @ 8 ohms/500 watts @ 4 ohms) and the amps "warm side of neutral" sonics work very well with my other components.
