Problem What to do
• Make sure the boat’s receiver is turned ON.
• Make sure the power supply of the boat is connected and
adequately charged.
• Make sure the receiver is not set to MUTE.
• Refer to the owner’s guide that came with your receiver.
• Check connections to both the speakers and the receiver.
Refer to “Test the speakers” on page 6. Correct any connection
errors.
• Disconnect the working speaker from the receiver.
• Switch the cord of the “faulty” speaker from its original
receiver connections to the other set of connections (the
working speaker was originally attached to those connections).
– If the speaker now works, the problem is in your receiver.
– If the speaker does not work, continue below.
• Remove the cord from the working speaker and connect it to
the “faulty” speaker and either set of receiver connections.
– If the speaker now works, the problem is in the original speaker
cord.
– If the speaker does not work, the problem is in the speaker.
• Follow the same procedure for the problem of no sound from one
speaker, as outlined above.
• Adjust the bass and treble controls on the receiver.
• Check the connections to make sure they are correctly in phase
(+ to + and – to –). Refer to “Test the speakers” on page 6.
Maintaining Your Speakers
Cleaning the speakers
Wipe the grilles using a soft cloth dampened with a mild detergent, such as dish soap. When
cleaning near the speakers with a hose, be careful to avoid forcing water behind the grille,
onto the driver, or into the acoustic ports.
No other regular maintenance is required.
