Wiring a Single Pull Single Throw (SPST) Relay
The SPST is necessary to protect the stereo in systems
with multiple amplifiers. The SWA6+ remote and trigger
wire provide 2A max current. While this enough to
power a single amplifier, complex systems with multiple
amplifiers will require a SPST relay.
Position 30:
requires 12VDC from the main power
source (12V battery, power supply etc). This should be
the same power source that is powering your stereo.
Position 85:
this is where you connect your ground from
your power source (12V battery, power supply, etc.) This
should be the same ground reference as your stereo.
Position 86
: position 86 is triggered 12V, and is sent when your stereo is powered on.
For Aquatic AV stereos position 86 can be connected to either the blue remote wire in the harness
or the brown 12V trigger on the rear of the unit. The differences are below:
Blue (recommended): The blue (remote wire) provides a 12VDC output when the stereo is
powered on. Meaning as soon as the stereo is powered on the blue wire sends 12VDC through
the relay powering on the amplifier.
Brown: the brown (12V Trigger) provides 12VDC output when it is triggered via the lightning
bolt icon on the faceplate or handheld remote. This setup is more advantageous is a more
complex system with several zones, as it gives you control of when an amp is on or off.
Position 87:
this is the 12VDC output that you will provide 12VDC to the remote turn on to the
amplifiers in your system.
