Adding a cooling fan?

[95BlackGA 5,000+ posts]

I want to know how exactly you add a cooling fan to my amplifier. I've been on Bcae1.com and read everything, but I need something that's not so complex in explinations. Do I just get a fan, and put the positive to the amps power wire (of course with a fuse) and ground the grounding wire?

You will want a relay. See this link, the 5th diagram down

^u didn't post a link.

But ya, generally just a relay. U can set it so the relay turns on ur amps and fans at the same time, or u can get a separate relay with a switch so u can turn on the fans whenever u want. Just really depends on how complicated u want to make it.

PS if u do it the way u stated the fan will always be on, 24/7. Thats why amps have the remote turn on input wire.

It's simple. Get a 30A SPST automotive relay. Then wire as follows (the numbers will be next to the plugs on the relay):

85: remote wire from your h/u

86: ground

30: 12v

87a: empty

87: outputs to accessories (fans, lights, amps, etc.)

The accessories wire to 87 will turn on when the h/u is turned on. You can add a toggle switch in line to anything you want to control on & off by an independent switch.

Thanks, I have a few of them relays lying around my house, when I get some more connectors and wire, I will do this. Since it's an ugly amp, should I just make a new cover too, or sand it and paint it which ever color I want, and mount the fans to the cover?

i have ran 3 fans off my remote line (along with the three amps) with out any problems...hook the hot to the rmt and ground it to the amp's ground. that easy.

Why not just tap into an ign switched 12v lead from fuse panel?
