Fan wiring - amp rack

[jleger98]

anyone ever thought about using a temperature sensor to turn the fans on??

I have no idea where to get such a thing, but that way the fan only runs when and if it gets hot in the compartment.......anyone??

Lots of people put thermostat switches that kick the fans on at a certain temp. There's even some fan that have a built in thermostat that Stinger and others sell. I just would rather have my fans on anytime my amps are on.

That would be a safe way to ensure the fans are on. You could also attach them to the yellow antenna up wire if you have one.

Will only be on if the radio is being used. CD or AUX will not have power to the ant.

I read this thread and didn't comprehend anything. We wanted the fan to turn on at the same time as the amp as well. We were told to connect on of the three wires on the fan to the REM, and another to the ground. Later we found out that we cannot do that with the model amp we have or something... So we ended up have in tied in with the key so whenever the key is on or on ACC the fan comes on whether the stereo is or not.

The reason you were not getting power there is that a remote only has about 1.5 amps on the line. That is not enough for the fan to run. You would need to use a relay to allow the low amperage rem wire turn on a higher amperage wire.

I'm wanting them to come on at the same time as the amps, and be on whenever the amps are on.

In that case you can use a standard single pole single throw relay. Connect the relay out to all the remote signals and to the fans power. Connect the radio remote line to the relay trigger. If you wanted to keep the ciruits seperated (which is not necessary) you can run a single pole double throw, and connect the remotes to one out, and the fan power to the other out.

You can get them at mouser.com, and wire it in series with a relay trigger. When the temp gets to the right point, the circuit would close, and trigger the relay.

Perfect... exactly the description I was needing! Thanks Spharis!
