As for the speaker output, I had something like the following in mind.
(Posting from Image 6T specs)
"INPUT POWER (RMS, Clipping <10% Time)
Recommended 10-200 Watts
Program 150 Watts
Dynamic Peak 300 Watts"

I have checked with someother speaker specs but not all of them list this kinda info......may be this is non-standard info. May be I should get my speaker basics straight

Thanks much all for your responses.
