Tip & How-To about Car Audio & Video
Mounting your Amplifier The mounting position of your amplifier will have a great effect on its ability to dissipate the heat generated during normal operation. It has an ample heat sink for heat dissipation, and also designed with a thermal shut-down protection circuit ( most amplifiers) making it reasonably tolerant of mounting variations. Any configuration with allows moving air to be directed over the cooling fins will improve heat dissipation dramatically, DO NOT enclose the amplifier in a small box or cover it so that air cannot flow around the heat sink fins. Temperature in car trunks have been measured as high as 175 F ( 80 C) in the summer time, since the thermal shut down point for most amplifiers is 185 F (85 C), it's easy to see that it must be mounted for maximum cooling capability. To achieve maximum advantage of convection air flow in an enclosed trunk, mount the amplifier in a vertical position, on a vertical surface. Cooling requirements are considerably relaxed when mounting inside the passenger compartment since the driver will not often allow temperatures to reach a critical point. Floor mounting under the seat is usually satisfactory as long as there is at least 1 inch (2 cm) above the amplifier's fins for ventilation.
