INSTALLATION
We recommend you have the installation done by an Authorized VVME Dealer. The
ground wire should be connected directly with the chassis of your vehicle which should
be a metal to metal ground point connection. The amplifier must be mounted securely at
a solid, dry and low vibration surface in the trunk or passenger area. Mount the amplifier
in an open air area to insure proper heat dissipation. Mount the amplifier in a place where
you can access it easily to set the input controllers. Install all amplifier cables as far as
possible from car electrical cables such as the car ignition cable.
