Correct (yes brake lights were already suspect but wanted to throw it out there before tearing things apart). The interesting thing is that this was present in my old configuration, which I completely removed and later reinstalled with the new amps.

It's louder now with more power but wiring to the new stack is completely new . It rarely bothered me before; but now, if I have no music playing before driving off and my foot is on the brake, it drives me nuts.

The "buzz" is the tailights lighting up and the audio picking it up via a weak ground.
I will pull the connector to the tail and check if it remains.

Thanks to both of you for your time and responses
