Do not modify or remove any original component parts of the subwoofer. Doing so could cause
damage to the unit allowing water to ingress. A unit with water ingress should not be charged
due to potential risk of fire or shock.
Please exercise care and good judgment when using your subwoofer. Audio levels should be
appropriate to your environment, comply with all local regulations, and always ensure that you
can hear and be aware of any potential hazards around you.
You should always
1) Use the subwoofer in accordance with any music or noise rules and regulations.
2) Properly seal the unit prior and after each use when in humid or water environments to avoid
water damage to the internal components. Salt water / air is particularly corrosive. Always
make sure that the gaskets are sealed when in salt water environment and the unit properly
rinsed off after use.
3) Properly clean the ECOXGEAR and ensure the gaskets have no sand, dirt, or water on
them prior to storage or removing the back cover.
4) Store your unit with all caps properly sealed to avoid long term internal moisture damage
inside your unit.
5) Return the ECOXGEAR to Grace Digital if you suspect water ingress into the unit or if the
unit has experienced a severe impact that may have affected the integrity of the unit to
take on water.
You should never
1) Never power your ECOXGEAR unit if you suspect water has entered the device. Powering a
device with water inside could be potentially hazardous and cause fire or a spark.
2) Never use your ECOXGEAR if you have dropped it or thrown it against a hard surface
which may have destroyed the integrity of the subwoofers, housings, or gaskets. In the event
of a severe impact to your unit please return the unit to Grace Digital to review for
potential damage.
3) Never open the cap in a water environment. This could cause water to ingress
into the unit which could potentially be hazardous and cause a fire or a spark.
4) Never attempt to fix, repair your ECOXGEAR unit. Please send it back to Grace Digital for
any assessments and repairs.
Connecting to 12VDC
Power Supply
The Underseat Bluetooth Subwoofer does not have an
internal battery. It must be connected to an external 12VDC
power supply to function. When you install the subwoofer to a
battery or a voltage regulator on a Yamaha WaveRunner, you
need to make sure that your WaveRunner battery or battery
pack terminal voltage is 12VDC. If the battery terminal voltage
is not 12V, you will need a DC–DC converter with output
12V/10A Connecting the subwoofer to a non-12VDC power
source will lead to a malfunction or damage to the subwoofer.
WARNING: Even when powered off, the subwoofer will
draw a small amount of power from your battery. To prevent
draining your battery when your subwoofer or powersports
vehicle are not in use for more than 48hrs, we suggest
unplugging the subwoofer from the battery or adding toggle
switch. (Toggle switch sold separately.)
