Important notes

3

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 red 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 which 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 from the metal 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 boats 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.
