IMPORTANT INFORMATION

Please read these notes before you begin installation. We also strongly recom-
mend that you thoroughly read and understand the installation instructions
included.

Avoid over-driving your speakers

Follow the instructions given to properly set gain and frequency adjustments. If your

system configuration results in settings outside the typical range and something maybe

wrong, please contact your local Aquatic AV dealer or Aquatic AV Technical Support.

Check your battery and electrical system

Low battery conditions and poor electrical systems should be diagnosed and corrected

before installing your amplifier. Old batteries may be good enough to start your engine

but may not be up to the task of powering a high output audio system. Running your

amplifier in a low-voltage situation can cause premature distortion, fuse blowout, and

system shutdown.

Ensure proper power and ground connections

Never connect or disconnect the control cables with the amplfier(s) powered on.
Always disconnect your battery before working with your electrical system, and keep it

disconnected until you are ready to test.
Cover all exposed wires to avoid shorts.
Make your power and ground connections exactly as the instructions specify.

75% or 3/4.

wires as the signal input.

Set to ‘LP’ to allow all

frequencies below the

‘Cross Over Frequency’

setting (these are ‘bass’

frequencies for when

running a subwoofer).

Cross Over Frequency:
Used to the set the

frequency by which the

‘Hi/Low Pass Filter’ starts

filtering or removing

unwanted frequencies.
