Well, my amps are in a box with plexi over them. i have one fan blowin air in on the right, and one sucking air out on the left. But Im not sure if your amps are completly enclosed like mine or not. The fans that I got only have 2 wires. Not sure what the third wire is. Oh, and I used a relay and spliced a wire off of the remote lead to activate the fans when the stereo is turned on.
