plus
if/when i get a relay, HOW do i connect it, can someone give me step by step? I plan to use three amps.
thanks for anyone who can write it up for me =D.
pictures up soon of my progress.
Relays are a whole world in themselves, and have to rank in the top 3 things audio installers / hobbiests should learn to use. Maybe we'll do a relay class at one of the meets, or something. The secret is to learn how they work, vs. memorizing lots of diagrams.
Your case is pretty simple, if I'm reading it correctly. You have a low current 12 v lead, that you want to use to turn on several amps. Hook the relay up as follows:
Pin #85 to ground
Pin #86 to the 12v lead coming from your headunit
Pin #30 to 12v constant (like at your amps)
Pin #87 to the remote turn on connections on the amps you want to turn on.
Long story short, the relay is a magnetic switch. When it power at power at #86, it will pull a contact over, that will connect pin 30 to pin 87.
