... basically im running it off the syn6
Channels 5 /6 are bridged and have the ability to be controlled by a bass knob.
Lemme see if i can find the pic of it...
I doubt you can see it here, but its on the right side of the dash, blocked by the steering wheels. It just the "bass knob" that hooks up to the amp via the telephone wire. Since channels 5/6 are running the tower, it mutes them when u turn it down. Very convenient.
