Installation Tips:
Make sure that all grounds for the radio, the WS 420 and the amplifiers on the system are shared.
You may need to re run the factory grounds for the radio and run a new ground for the EQ so that
all are grounded at the same point. Most larger systems in boats will have multiple batteries. It is
recommended to use a ground distribution block to share all the same grounds for the audio
system. It is also recommended to do the same for power. You may want to install a relay on the
remote turn on to keep any noises like turn on pops from happening.
Please use high quality shielded RCA cables. The WS 420 is a high voltage line driver. When
providing this much voltage to the amplifiers. You are more likely to pick up ambient noise if
lower quality cables are used. If you are hearing “hiss” or noise on the system. Re check your
wiring and gains. If set up properly, the system should have little to no ambient noise. Some
boats will always have some noise as there is no true ground in a boat and there are other
electronics that may be interfering with the audio system. This is usually not noticed with lower
powered systems but has always been in the system. Just not as audible with the low power. If
this is the case. Check with a authorized Wet Sounds installer. They may need to check the
other components in the boat or use a noise filter with the system.
Since the WS 420 is an equalizer. You will not need to use the radio settings. Make sure the
treble and bass on the radio is always flat. And if using an Ipod or MP3 player. Please make
sure there is no eq setting turned on. That source should also be set to flat.
You are now ready to enjoy your system.
