I'm going to attempt a car amplifier installation in the next few days. The amplifier will be based in the car boot and i'm going to be making a flase floor which will hide the amplifier underneath. To keep things cool, i'm thinking of installing PC fans into the floor so that it can blow cool air under the floor and suck hot air out.
PC fans usually have 3 cables. Red, Yellow and Black. I just wanted to know which cable is the power cable.
red and black are the ones you want Red being +12 volts. the yellow is for the tacho and only there on expensive fans, buy cheap ones with no tacho and there will not be a third cable, you wont need the quietest fans on the market either.
I'm going to use PC fans to cool my car amplifier.
Main reason is that I don't want the amp display for all to see and steal. so I'm going to hide it under a false floor. Amps produce alot of heat under strain so I need to install some sort of ventilation i.e. fans.
I read some articles and PC fans where mentioned but the problem is that I don't know what the 3 wires are that all common fans have. i.e. Red, Black and Yellow.
