RMA 500.1 & RMA 500.4 Amplifier Owner’s Manual
Rev. 09-Mar-10
Pg. 2/8
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.
This RMA Marine amplifier uses a Full Range Class G/H topography that significantly improves
efficiency while enhancing sound quality. Do not be fooled by the small size. Class G/H amplifiers
make more power for their size than traditional designs and offer much lower THD and higher damping
factors than Full Range Class D designs.
Installation Instructions
Roswell Wake Air RMA series amplifiers are designed for easy installation in your boat. To ensure
proper operation of your new investment, please follow the suggestions we have listed below:
Warning
Please check the suitability of the installation location before you begin. Do not cut any of the boats
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.
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 proper 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.
