The “Line Output Converter” that I chose is the “Kicker 46KISLOC2” which has a “remote turn-on output” (so no need to connect to 12v).

[QUOTE="PatLap, post: 8871653, member: 690910"] OHHH YESSS😀! Thanks 👍 Be ready to get lots of info Lol! ***Sorry for the delay of my reply, I've been trying all morning to figure out why my attachments are appearing sideways! I tryed everything and still doesn't work...
