To avoid unwanted ignition noise caused by ground loops, it is essential that the Amplifier be grounded to a clean, bare, metal surface of the vehicles chassis.

Note :GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FT ( I METER).

Planning and Mounting Your System

The mounting positionof your Amplifier wlll have a great effect on its ability to dissipate the heat generatedduring normal operation.

Under normal conditions, the heatsink will dissipate sufficient heat to avoid thermal shutdown. However please do not install the amplifier in a wooden box or similar device as this will prevent heat dissipation into the atmosphere.

Temperatures in car trunks have been measured as high as (155'F)in the summer time. since the thermal shut-down point for the amplifier is (158'F)it is 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 horizontalposition.

Cooling requirements are considerably relaxed when mounting inside the passenger compartment since the driver will not offen allow temperatures to reach a critical point. Floor mounting under the seat is usually satisfactory as long as there is at least

1inch of clearance (2.54 cm) above the Amplifier'sfins for.ventilation.

A.Select a suitable locationthat is convenient for mounting, is accessible for wiring. And has ample room for air circulation and cooling.

B.Use the amplifier as a template to mark the mounting holes. Remove the Amplifier and drill holes. Use extreme caution, inspect underneath surface before drilling!

C.Secure the Amplifier using the screws provided.
