4.1.2 External Speaker

DO NOT ground the radio's speaker leads. This system has a floating speaker output (dc
voltage on both leads); damage to the audio circuit will result if either lead is grounded or if
they are shorted together.
The external speaker kit includes a trunnion bracket that allows the speaker to be mounted in a variety
of ways. With the trunnion bracket, the external speaker can mount permanently on the dashboard or
in accessible firewall areas. The trunnion allows the external speaker to tilt for best operation. Mount
the external speaker out of the way so that it will not be kicked or knocked around by the vehicle occu-
pants. Mount the external speaker as follows:
1. Use the external speaker mounting bracket as a template to mark the mounting hole locations.
2. Use the self-drilling screws provided to fasten the trunnion.
3. Attach the external speaker and fasten to the trunnion with two wing screws.
4. Route the speaker wires under the carpet or floor covering, or behind the kick panels. Be sure the
wires are out of the way and will not be snagged and broken by the occupants of the vehicle.
