Not home theater but car radio. The radio in my car has line level outputs via 4 RCA cables to an external amplifier. The right hand side of my audio (front and rear) is stronger than the left. I am suspecting the radio because when I plug an rca cable directly into the amp both left and right channels are the same. 


I am trying to measure the voltage of the rca outputs from the radio but cannot get a reading. How do you do it?

With an oscilloscope. Perhaps write an audio file of just a 50hz tone and try measuring that with a digital multimeter on the AC range.

Swap L and R around and see if the problem persists.

One of my head decks had a "driver mode" which did something similar to make the other side speaker louder. Didn't really help.
