Trigger Lead??

[VR_Berly]

Where does the trigger lead run to on the amplifier? im not sure.

[VrWagz1]

the remote terminal, usually between the + and - termonals

yep thats right, It goes from the "signal" or "remote", "trigger" whatever they call it on the head unit, 90% of the time its the blue wire, and goes to the "rem" on the amp

on my amp its called "system control" and its between the + and the ground wire. all it does is tell the amp to turn on when the head unit / accessories turn on.
