[QUOTE="L1ttlet, post: 8687221, member: 675617"] So after daisy chaining my 2 amps and 2 volt meters off the same remote wire, my 4 channel will shut down when a certain volume is hit. I now realize that I need to get a relay. I've been researching relays. There are 4pin- 8pin maybe more. What is the point of all the pins. I understand Pin 85- to ground Pin 86 - to remote turn on from headunit (Or u can switch the two with no effect) Pin 30- to +12volt connection Pin 87- to accessories desired to run What is all the extra pins for????? Do I need to fuse the wire going to each amp from the relay at like 5amps???? If not why? I want to run my cooling fans off of it and probly leds in future. So a 12 volt 4pin 80amp should suffice- 2 5amp draw cooling fans 2amps 3 stinger voltmeters Plus leds. I'm pretty confused as why I'd want 80 amps going to amps or even 5-amp cooling fans and not fuse the wire- do I fuse between relay and accessory ran? [/QUOTE]
