Yes heat is bad for an amp and if built right will send it into thermal shut down. If not and fused properly will keep popping fuses. If neither then may start a fire. The end result of installing an amp in the engine compartment could vary from less than ideal to oh sh*t.
The two primary locations people are installing amps are behind the helm, or next to the batteries. My current and last boat had them by the batteries and worked fine. The only drawback to the way Yamaha installed them by the batteries is they put the controls facing away from the opening....D'Oh!!!!!
