“With this receiver, what is the proper wattage in speakers I should use x 5? One review said, and in the instructions, 90w rms music power and that the 145w is not the true rms music power or effective value, it's only the peak or max. Thanks.”

The 145W output power rating is using 6 ohm speakers at 1 kHz with 0.9% THD (total harmonic distortion) with only one channel driven. Not by any means a very meaningful spec. The 90W rating is for two channels driven with 6 ohm speakers with the THD at 0.09% from 20 Hz to 20 kHz. This is much more meaningful and is enough of a standard spec to be useful when comparing receivers. Note: With all 5 speakers driven the output power will be noticeably lower. I was unable to find an independent review that tested the output power with 5 speakers driven. Also note that none of these numbers are the so-called "music power," a totally bogus spec that was used back in the last century to promote cheap amps.
Sorry, there was a problem. Please try again later.
