INSTALLATION

Due to the high power output of the X-A90M/ X-A70F/X-A90V considerable heat is produced when the amplifier is in operation. For this reason, the amplifier should be mounted in a location which will allow for free circulation of air, such as inside the trunk. For alternate installation locations, please contact your authorized Alpine dealer.

Mount the amplifier before installing the Terminal Cover (F)/(L)/(R).

1.Using the amplifier as a template, mark the four screw locations.

2.Make sure there are no objects behind the surface that may become damaged during drilling.

3.Drill the screw holes.
