Output test on amp

Is there a way to test frequency response vs dB output with a test record and multimeter?

im trying to determine if both channels are outputting all frequencies at equal outputs. 
If not is there another way to achieve this at home.

I would get a digital test album like this one  https://www.hdtracks.com/#/album/5ddb5ef3848da9f501f6db95
Then you will need a broad bandwidth multimeter. This will check everything but your turntable. For that get the Hi Fi News Test Record.

Many amps actually go right down to DC. The upper limit is peculiar to that am and it's design but I no of no amp that does not pass by 20 kHz gracefully. What is it exactly that you are worried about and why?

Yes, the correct way to do it would be with a signal generator and an oscilloscope. I believe this would be an unusual failure mode for an amplifier but hey, it is a strange world out there.  I see no reason why imhififan's method would not work.
