As been stated...
Pre on first, amps second. Amps off first, pre second. Zero volume and mute. I don't have a 12v trigger on my pre, but do on my monoblocks. I wired one amp to trigger the other amp (one less button to push), and the JC-1's have a timer delay. So, one amp powers up nice and slow, then triggers the other amp, which powers up nice and slow.
