Remote wire and fans lalala

[Black Truck 10 10+ year member]

2 questions here:

I need to run remote wire for 3 amps, can I just connect all of the wires to 1 remote wire, then run that to the headunit? My plan was to just splice into the wire.

I purchased 4 fans, can I run all 4 of them off of 1 relay. Its the standard 30 amp car relay?

Run the h/u remote to the relay, and then split the wire off the output of the relay.

And yes, a 30A 12V relay will be more than enough for all the fans, amps, and any other thing you can come up with.

get a relay for the amp turn on wire as for fans do you want them to turn on when the ampsturn on if so add them to the remote wire relay

I wouldnt really need the fans except when the vehicle is on so I guess there all going to the relay. Ive got gobbs of 18 gauge, that should be sufficient enough?

18 ga is plenty. Use the relay to switch the amps on as well as the fans. That many remote on circuits are pushing it for most HU remote leads.

Im a big fan of wiring fans off a 12 v constant with a toggle switch in line.

Actually, the way I would do it is run the remote to a 12V relay and then run the relay to one of these:

And then branch off the terminal strip to each device.

That's really the proper way to do it vs. pigtailing off of a single wire.

Problem with using a barrier strip like that is you have to amke a bunch of jumpers to distribute the power. Total PITA. I just get an oversized slide connector for the wire I'm using and run a bunch of wires into it. From there plug the connector into the switched output of the relay. If you want a "proper" way to do it, you build a small buss bar and run it all to that. If you want to get really anal, you get a marine fuse/distro panel and you fuse all the outputs as well.

I use a small bus bar off my relay t power my amps. Its like 6" long and has like 8 holes with 8/32 screw holes. makes it easy.

Like these. Plus thy have mounting oles on the ends.

Trust me, I'm an engineer and barrier strips are the proper way to make multiple power connections.

Unless, you've developed something completely new that no one is aware of. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

Wow this thread just got cocky...

So if I use a barrier strip is that aft my relay then? I honestly couldnt imagine it any other way.

I might just run to the local radioshack and pick up one of these tomorrow.

So on that barrier strip do you just run my power from the relay to the strip then just connect all the fans and everything to the strip?

Sorry, I didn't mean to be cocky, I just hate to see people get bad advice by people who just don't know what they're talking about.

It frustrates me. //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif

im in engineering at school to but still, im not gonna lie it doesnt bother me at all. The only thread comments I hate are people that only respond to a new thread from a new guy by doing this.

SEARCH

Thats what I hate, I honestly could just go stab the guy that does that, that really realy bugs me.

Barrier strips are the way to make multiple connections, but not to distribute a single source. There's a difference. And engineers rarely do things in a way that makes sense.

Hahahahahahahahaahahahahaha, pure ignorance

You obviously have never taken an electrical engineering course or you would know how wrong you are.

Please explain technically why barrier strips wouln't work in the application?

Quit trolling you ignorant POS!
