SAFETY:

This product has a limited life span of use and should be replaced when it shows obvious signs 
of wear. 

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.)

battery terminals.

Use Caution:

 Do 

NOT
