10. tallations can be tricky espe cially for first timers For this reason you may want to consider using a pro fessional installer who has the tools and more Importantly the experience to do the job right If you decide to install your equipment yourself we hope that this manual will serve as a helpful guide LOCATION amp MOUNTING The first step in installation is thorough planning Choose the location for your amplifier carefully The amplifier should be located in either the passenger compartment or the trunk never in the engine compartment or in any outside location exposed to dirt and moisture Adequate ventilation is important allow enough space so that air can circulate around the heat sinks If the amplifier is mounted vertically mounting the heat sink fins vertically will optimize heat dissipation The Class A 50 amp Class A 40 in particular tend to run hot because of Class A operation This is no cause for concern provided that ventilation is adequate Make sure that the installed amplifier will not interfere with normal operation of the car For example if you locate the amplifier under a front seat make sure that it does not interfere with seat adjustment that it will not be exposed by repositioning the seat and that the seat does not press on the amplifier when occupied If you install the amplifier in your trunk make sure that it is not an obstruction It is best not to locate the amplifier near your antenna because the
