Notes
Warning
If you do not have experience with automotive or marine electrical and mechanical systems please contact a professional installer.
Paying a qualied installer is almost always cheaper than paying a dealership to repair your boat.
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.
Location of the Amplier
The amplier must be securely mounted to a solid surface. Please select a dry location such as in the storage compartment. Do not
mount the amplier to any area that may have excessive vibration (like the subwoofer box), under any cup holder drain lines, or
under ballast drain/vent ttings that may leak water. Position the amplier in an area that receives sucient airow and mount it
vertically or completely at for optimal heat dissipation.
Supplying Enough Power
The R1 Series ampliers are capable of signicant output. In order to achieve this it is critical that the ampliers 12 Volt wiring is
adequate to provide the necessary power to the amplier. We recommend using 4AWG wire for all power and ground connections.
Be sure to fuse the power wire appropriately for the amount of current being drawn.
The Ground
The ground wire should be connected directly to the battery of your boat. Remember, the ground must carry the same high current
as the positive wire.
RCA Cables
The R1 Series ampliers feature dierential RCA inputs for maximum noise rejection. However, it is still a good idea to follow best
practices to minimize the amount of interference in the signal chain. To reduce the risk of noise, run all signal cables away from any
power supplying wires.
Protection Indicator
This amplier is equipped with an advanced protection system. If for any reason this unit goes into protection mode it will ash a
solid single red LED light found on the control end of the amplier. In most cases, the amp will automatically recover once the issue
causing the protect mode is corrected.
Installing Multiple Ampliers
Roswell oers a stacking spacer for use with R1 Amps (C920-1830). These allow you to stack ampliers on top of each other securely.
Roswell recommends stacking a maximum of four ampliers when done on a at surface or two ampliers when mounted on a
vertical surface. It may be necessary to provide more airow for more ampliers as more amps will generate more heat.
