for purchasing the world’s best value marine subwoofer.
After years of development and testing, we are proud to introduce
the RMA Series marine subwoofers, built to outlast - and outperform
- every other value marine subwoofer on the market. We at Roswell
started a revolution in the wakeboard industry back in 1998, and
have since expanded into marine audio and other branches of the
marine industry. Even now, nearly 20 years later, we continue to
push the boundaries.
We are fully committed to going past industry expectations every
day to make your boating experience more enjoyable. With the
input of our dealers, team riders, and boaters around the world,
our goal remains to redefine the marine industry day in and day
out. We will not be confined to our desks; we are out on the water
testing our full line of products to ensure your days on the water
are as hassle-free and enjoyable as possible.
If you have any questions about your subwoofers or questions
regarding installation, please contact your authorized Roswell dealer.
If you have further questions, please don’t hesitate to contact us
directly at (321)-638-1331 OR by emailing support@roswellmarine.com.

If your vessel does not have a battery switch, simply disconnect the negative lead
from the battery terminal.
• Use extreme caution before cutting and drilling holes to avoid damaging fuel lines,
hydraulic lines, or existing electrical components.
• If additional wiring is required, we recommend using at least 12 gauge wiring and
running all wires prior to installing the speaker. Longer runs may require 10 gauge
wire to prevent negative impacts on sound quality. Leave some slack in the wire to
allow for easier installation and to prevent tension on the wire.
• Avoid running wires near sharp edged surfaces. Never run wires exposed on the
grommets to protect the wire.

To ensure your subwoofer installation results in the highest possible
performance, please carefully note the following information
RMA subwoofers are designed to be extremely flexible and are able to work in a
variety of enclosures, including no enclosure at all. This is referred to as an ‘infinite
baffle’ or ‘free-air’ installation. In an infinite baffle configuration, the key to good
sound is ensuring the sound wave coming from the front of the speaker cone is
acoustically isolated from the sound wave coming from the rear of the cone. In
other words, if your chosen mounting location is located near a vent, door, or any
permanent opening allowing the free movement of air from the inside (rear of the
cone) to the outside (front of the cone), you will likely experience poor output as
the low-frequency sound waves run into each other and cancel each other out.
If you do not have a location that allows for good isolation of the front and rear
sound waves, we recommend installing your RMA subwoofer in the largest sealed
enclosure that is practical to fit in your chosen installation location. However, a
ported enclosure will allow for greater output, on average offering a +3dB increase
over a sealed enclosure, with the tradeoff being that the enclosure is more
complex to design and build. If you wish to build a ported enclosure, see the table
on the next page for some recommended enclosure configurations.
