You want to mount the amp in a well ventilated around. Some people actually mount them on the bottom of the passenager seat. But don't be surpirsed if ur amp shorts due to overheating. I usually mount amps in the trunk, right on the backside of the seats. That why there's enough air to pass freely, cooling ur amp down. btw...don't mount it near the gas tank because heat and gas don't mix! g'luck!
