Important notes
Prior to the final installation, carry out a sound check. If high distortion or intermittent
sound is experienced, it is possible that the wiring from the CD receiver to the boat's
electrical system is poor or that the battery needs recharging.
If the battery and its charging circuit are OK, then rewire the yellow fused wire of the
CD player directly to the positive terminal (+) of the boat battery.
Marine accessory shops stock the connector blocks and the 10 Amp cable that may
be necessary for extending the fuse wire connection.
Grounding
Make sure that the black wire on the wiring harness is connected to a good ground
point on the boat. If the chassis of the boat is used as a grounding point, make sure
that the surface is scraped clean of paint before attaching the wire to it.
It is preferable to connect the black ground wire directly to negative terminal (-) of
the boat battery.
Warning: polarity...
This model is only suitable for use in boats which have a Negative ground system,
e. g. : the negative terminal of the boat battery is connected to the chassis.
Connecting the Speakers and Power Cables
Before you wire your system, disconnect your boat battery's positive (+) cable.
This helps prevent damage in case of a short. When you complete the wiring,
reconnect the battery cable and test your marine stereo. When connecting your
marine stereo's black ground wire, be sure to connect the wire to a metal part of
your boat or preferably to the negative (-) terminal of the boat battery.
