So PA amps have this "LED/FAN" harness that let's you connect led/fan (duh! lol) to the amp. It is a pretty cool feature to have if you are plannign on adding leds/fans to dress your install up as there's no need to run any other wires/swiches/relays for these small things as amp itself is a on/of switch, ground and constant.... cool
You think i can hook up let's say a line driver or an active crossover to this harness without getting a "turn on/turn off thump"?
According to what i know about this on/off thump as long as your amp turns on AFTER the rest of components are already on and shuts of BEFORE all of them do there will not be a "thump".
