your battery could vary depending on it’s Amp-hour rating and condition.
If you do not run your boat’s motor regularly or your battery is not kept charged
between outings (e.g. Solar or wind charger), we recommend you disconnect
the Red lead each time you secure your boat. This is easily done by connecting
the Red lead via a Master switch which can be switched off after each outing.
Speaker Connections
When connecting the speakers, observe the correct polarity as shown in the
diagram. Incorrect polarity will result in a reduction of Bass response and stereo
effect. The use of speakers with an impedance of less that 4 Ohms is not
recommended, as they will cause excessive loading of the MST70’s output
circuit.
Caution:
The MST70 is a four speaker system that requires 2 separate wires
for each speaker.
•
DO NOT
connect the negative (-ve) terminals of the speaker wires together

Damage caused by the above will not be covered under warranty.
Connect all four speakers as shown in the diagram. Adjust the Fader control
