JBL GTO-3501 Monoblock Bridging Upon Input?

Hey guys,

I'm currently working a project that requires an audio signal, so I figured I'd tap off my preamps. When testing the voltage output of my head unit, however, I noticed that my subwoofer becomes quieter when I have only one channel plugged in. Because we are working with bass, it obviously does not matter which channel I have in.

So the question becomes: Does the amp invert one of the channels to create a bridging effect? I don't want to pull the amp apart to understand what is causing the amp to operate this way.

Thanks in advance!
