R1 Amp Installation Instructions

Notes
Warning
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.
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 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), under any cup holder drain lines, or under ballast drain/vent fittings that may leak water. Position the amplifier in an area that receives suficient airfiow and mount it vertically or completely fiat for optimal heat dissipation.
Supplying Enough Power
The R1 Series amplifiers are capable of significant output. In order to achieve this it is critical that the amplifiers 12 Volt wiring is adequate to provide the necessary power to the amplifier. 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 amplifiers feature difierential 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 amplifier is equipped with an advanced protection system. If for any reason this unit goes into protection mode it will fiash a solid single red LED light found on the control end of the amplifier. In most cases, the amp will automatically recover once the issue causing the protect mode is corrected.
Installing Multiple Amplifiers
Roswell ofiers a stacking spacer for use with R1 Amps (C920-1830). These allow you to stack amplifiers on top of each other securely.
Roswell recommends stacking a maximum of four amplifiers when done on a fiat surface or two amplifiers when mounted on a vertical surface. It may be necessary to provide more airfiow for more amplifiers as more amps will generate more heat.
Sensitivity
Due to the wide range of head unit output configurations all RMA amplifiers have an adjustable input sensitivity. The level is not a volume control. It is used to properly set the ouput of the amplifier based on the output voltage of the source unit, and to ensure the speakers are receiving clean power at an appropriate level. With the sensitivity turned up, the amplifier will reach maximum output at a lower volume setting on the source unit.
There is no correct sensitivity setting suitable for all applications as head unit preamp outputs vary. If you are unsure on adjusting this settings, consult an audio installation professional.
Crossover Controls
A crossover is a circuit that filters unwanted frequencies. A tweeter can easily be blown by bass frequencies if they are not filtered out. A subwoofer will not sound natural if it is playing mid range frequencies. Careful adjustment is needed to ensure that all speakers are playing the right frequencies and that they are left with no gaps in the frequency response.
The R1 Series amplifiers feature calibrated potentiometers in the crossover section which allows for very precise adjustment of the filter frequency. The 900.6 and 650.4 amplifiers feature a single crossover. Simply select whether you would like the crossover to be a low-pass or high-pass, and adjust accordingly. The 1000.1 also features a Subsonic (infrasonic) filter, which is explained in detail below.
Full – Allows the full range of frequencies to pass through.
HPF (High-Pass Filter) – A high-pass filter allows high frequency signals to pass through while reducing all signals lower than the cutofi frequency setting on its dial. LPF (Low-Pass Filter) – A low-pass filter allows low frequency signals to pass through while reducing all signals higher than the cutofi frequency setting on its dial. Subsonic (1000.1 & 550.2 only) – A Subsonic, or infrasonic, filter is essentially a high-pass filter dedicated to removing the lowest frequencies. This allows you to remove unwanted frequencies in order to protect your subwoofer from excess power, or to prevent it from unloading when it is in a ported enclosure or free-aired application. In most cases this filter should be set at around 30 Hz (12:00 position on the dial).
Phase Control (1000.1 & 550.2 only) – The Phase control allows you to fine- tune the output of the amplifier in order to ensure that the sound from the subwoofer is in-phase with the sound with the rest of the audio system maximize the bass output. Depending on your subwoofer mounting location this may not need to be adjusted. If you are unsure on how to properly adjust this setting, leave it alone.
Bass Boost
All of the RMA amplifiers have an adjustable bass boost from 0-18 dB @ 45 Hz. Adjust the Bass Boost carefully – the response on the power output is tremendous!
Remote Gain Control
The 1000.1 Amplifier includes a remote gain control module that can be plugged into the amplifier to allow easy reduction of the gain setting without accessing the amplifier.
RCA Inputs
All R1 amplifiers feature switchable difierential RCA inputs to maximize noise rejection.
Input Select Switch
The 900.6 and 650.4 amplifiers feature an input selection switch that will allow you to set which RCA inputs feed signal to the amplifier. You can choose a dedicated RCA input for each channel, or to have one pair of RCAs to supply the signal to all channels. The 900.6 also allows for 4 channel input to control all 6 outputs. This allows you to group channels together to easily interface with head units that feature zone control, or to use with our Dual Zone Volume Control.
NOTE: Set this switch before tuning your amplifier.
RCA Line Out
The 1000.1, 550.2, and 650.4 amplifiers have line out connections that allow you to connect multiple amplifiers together. The 550.2 and 650.4 line outs supply a full range stereo signal. The 1000.1 line out supplies a mono signal as it is designed to provide signal to additional subwoofer amplifiers.
Speaker Outputs
All R1 amplifiers are equipped with a block style terminal for speaker connection. Make these connections carefully and neatly. Strip your wire back 5/8” (16mm) and twist the exposed leads. Using a 2mm Allen wrench, loosen the terminal set screws far enough to allow the wire to fit. Insert them into the appropriate spot on the block terminal. Make sure that there are no loose or frayed strands of wire sticking out. If a wire comes in contact with another wire, the amplifier will go into protection mode. After  ightening the terminal set screws, verify your wires are secured in place by gently pulling on them.
Impedance
The 900.6 and 650.4 Amplifiers are 2 Ωstable on each channel, meaning that up to two 4Ω speakers can be wired in parallel per channel. When bridging channels the speaker must have a nominal impedance of at least 4Ω. Attempting to run speakers below 4 Ωwhen bridging channels could result in damage to the amplifier and will void the warranty.
The 1000.1 Amplifier is 1 Ω stable, meaning that up to four 4subwoofers can be connected to the amplifier simultaneously. If you are unsure about impedance matching or series vs. parallel wiring, consult an audio installation professional.
