Yes.I noticed mine is SPST and not SPDT. Still would work right?
Only have two amplifiers but want to run a relay anyway just because and if I decide later to run more its already in place just need to upgrade fuses. I want to fuse the battery wire going to pin 87 with a fuse. Do you have to fuse the individual remote wires going to pin 30 also? What fuse ratings should I use?Yes.
Also there's absolutely no reason to use 30A fuse for remote turn on wire. I'd say 5A is more than adequate and yes, a relay is the proper tool for the job if you're trying to turn on more than 1 or 2 things from the head unit. I've used a transistor before as well, but they're so small, get a relay and some female spade crimp connectors (or solder and tape) and call it a day.
I should have quoted this one.No. i said "i use a standard blade fuse rated to the wire used". the 30 is the the number of the pin on the relay. Battery source goes to pin 30(where the fuse needs to be), 87 goes to remote on your amps.
im my situation, i use 18 guage wire, and 3 amp fuses a lot at work. so thats what i used.
You just left it open ended. I was making sure it didn't come across that OP needed to use a 30amp fuse for this. That was clarified already, that he doesn't.the fuse holder is right.. But you can use Female insulated connectors on the same blade fuse instead of a holder for pennies..
That is what you'll want to fuse, ideally close to wherever you're tapping into +12 but 5A should be plenty.I want to fuse the battery wire going to pin 87 with a fuse.
