Well I was trying to wire up some 12V fans for my amp rack and something stumped me so I was hoping for some help. I've got three of these fans right next to each other, and trying to wire them together just to cut down on the number of wires. I hooked them up to a battery I have laying around, and no go (see diagram below). When I hook them up individually they work just fine. So someone steer me in the right direction please. Thanks.

You need to run a jumper wire (just a piece of wire) from the +(red) one on the left to the +(red) in the middle. Then do the same with the ground(black wire) And then it will work.

Hey How are you kicking your fan on? Are you using the remote wire for your amp's? or a switch?
If your using the Head unit kick on you might want to think about using a relay between your head unit and the fans/amp's

When I install a system I install a remote relay
so when the head unit powers up it kicks on the relay with the remote wire and I can power as many things as I want with out worrying that the head unit is not gonna have enough power to kick things on.
The black box is the relay im taking about
