measuring amp output voltage

emarald · 5th April 2003, 11:30 AM

My Kenwood amp shows 77voltsAC, (single tone@60hz), output in bridgemode with no load across the channel. Its rated output is 600Wrms in this mode. It blew my 250Wrms sub in 20 seconds, (playing bassy music), with about 65V-AC showing on the meter.
Question, is this voltage correct for the output or is it to high?

Well, if it blew your speaker, it was too high, eh?
