Roswell Marine Audio Amplifier Owner’s Manual
REV. 02-Feb-14
Thank you for purchasing a Roswell Marine Audio (RMA) Amplifier. Since 1998 Roswell has
been the world leader in wakeboard towers and accessories in the marine industry and is quickly
becoming a leader in marine audio.
This RMA Marine Amplifier uses a super-efficient Class D topology that significantly improves
efficiency while enhancing sound quality. The amplifier has been designed using the latest
available electronic technology, allowing you to produce high quality stereo reproduction in mobile
applications. This system provides low harmonic distortion, a considerable amount of reserve
voltage, and high temperature stability.
Installation Instructions
RMA amplifiers are designed for easy installation in your boat. To ensure proper operation of your
new investment, please follow the suggestions listed in this manual.
Warning
Please check the suitability of the installation location before you begin. Do not cut any of the
boat’s structure. Pay close attention to what is behind any bulkheads, panels and carpet. Often
the boat manufacturer will hide wires and cables in the exact location you may wish to install in.
The amplifier is sensitive to electrical and motor noise and interference from the amplifier may
affect your radio reception, try mounting the amp at least three feet away from the receiver.
If you do not have experience with automotive or marine electrical and mechanical systems please
contact a professional installer. Paying a qualified installer is almost always cheaper than paying a
dealership to repair your boat.
Location of the Amplifier
The amplifier must be securely mounted to a solid surface. Please select a dry location such as
in the storage compartment. Do not mount the amplifier to any area that may have excessive
vibration (like the subwoofer box) or under any cup holder drain lines that may leak water. Position
the amplifier in an area that receives sufficient airflow and mount it vertically or completely flat for
optimal heat dissipation.
Supplying Enough Power
Your amplifier converts power, or current, from your boat’s electrical system and turns it into high
power audio energy. If the amp does not get all the power it needs, it will not produce its full
output. If the voltage or current drops too low, the amplifier will drop below it’s rated output. Make
sure your boats charging system is in good working order. Any hi-performance audio amplifier will
increase the demand on your alternator and battery. If you are unsure, have your charging system
tested by a professional technician.
