AMPLIFIER MOUNTING OPTIONS

The HD900/5 has two mounting options to ease in installation.

Standard Mounting

The standard method of mounting requires removal of the four corner caps with the 4 mm hex wrench included with your amplifier. Using appropriate mounting screws (not included), secure the amplifier in all four corners and replace the corner caps to cover the screws.

Lateral Mounting Feet

Lateral Mounting Feet are also included with your HD900/5 to provide an alternative mounting option. Each mounting foot should be attached to the bottom of the amplifier by screwing the provided bolt into the bottom of the amplifier and up into the corner cap with the supplied 2.5 mm hex wrench. Next, using appropriate mounting screws (not included), secure the amplifier by its four Lateral Mounting Feet.

Check before drilling any holes in your vehicle to make sure that you will not be drilling through a gas tank, brake line, wiring harness or other vital vehicle system.

ConTROL PAnel SECURITY CoVER The HD900/5 features a Control Panel

Security Cover. When installed, the cover ensures that your amplifier settings are not accidentally changed while creating a clean aesthetic for the amplifier and your installation. The control panel security cover is pre-installed at the factory and must be temporarily removed for access to the controls described throughout this manual.

The security cover is secured by a single 2.5

mmhex-head screw at the far right of the panel. Loosen the hex-head screw to release the security cover (it is not necessary to completely remove the screw). To re-install the security cover once all adjustments have been made, insert the tongue on the cover’s left edge into the groove where the left- side heatsink meets the control panel, hinge the panel closed and secure the screw using the supplied 2.5 mm hex wrench. Do not overtighten the screw.
