My 93 ls400 has low audio volume from the front and rear speakers.. the woofer works great..

I have checked the speakers and wiring, and find no faults.

How can I test the output of the radio for correct power output...??

I am a longtime electronic hobbiest, so using a VOM and standard test equipment is not a problem for me..

But, I dont know the correct voltage output to the speakers at low and high volume..

Any help is appreciated..
