Super Small Multi-Channel
The new SS amplifiers are the latest in high speed, high current class D designs offering high power and superior sound quality in compact footprints. The classic DD AUDIO style heat sink is used in this upgrade for max cooling with 50% more side wall thickness than industry norms and extra long fins to increase surface area. All major components have been upgraded; higher current mosfets and output devices, increased power capacitors, a more powerful transformer, plus improved venting and PCB with twice the thermal capability.These new high-end mini amps are state of the art, no compromise designs yielding the best sound with unparalleled power to size ratio. The transformation is not only tangible, but audibly apparent.The SS4.500 is a 4 channel amplifier delivering a minimum of 125 Watts per channel from a mere 30 square inch footprint. This versatile, high speed, class D design can drive full range components and subwoofers through selectable high pass and low pass crossovers. These super small amplifiers are the ultimate combination of precision sound quality and installation ease.
For the SS Series the main design focus was to pack as much full-range stereo output capability as possible into as compact of a chassis as possible. We utilized discrete circuit class D technology for ultra low distortion levels that rival class AB designs. The resulting amp is capable of driving multiple driver mid-range and tweeter arrays while consuming less current, taking up less space and delivering more power.

Frequently Asked Questions
What does IPX-4/5 weather resistance mean for this amplifier?
IPX-4 provides protection against water splashing from any direction. IPX-5 adds protection against water jets. For a powersports amplifier, this means it can handle rain, spray, splashing water, and wet environments — though it is not fully waterproof and should not be submerged.
Can I run this amplifier in bridged mono mode?
Yes. The SPX350X2 delivers 350W RMS bridged into 4Ω, making it suitable for driving a single subwoofer or full-range speaker in high-output mono applications.
Can I link multiple SPX350X2 amplifiers from one audio source?
Yes. The AUX RCA pass-through output allows you to connect a second (or further) SPX350X2 amplifier directly from the output of the first, distributing a single audio source to multiple amplifiers without additional signal splitting equipment.
Why does this amplifier use an unregulated power supply?
Unregulated power supplies are better suited to applications with non-standard or fluctuating voltage — common in boats, ATVs, and motorcycles where charging systems and battery capacities vary. The SPX350X2 is designed to operate reliably across 8V to 16V.
What wire gauge do I need to install this amplifier?
Stinger specifies 8 AWG power and ground wiring for the SPX350X2. Using undersized wiring will limit power delivery and may cause overheating — always match or exceed the recommended gauge.

Bluetooth is for tuning only and does not support audio streaming.
Universal and Maestro Mode Flexibility: In Universal Mode, the DSR1 operates with RCA or high-level inputs and any aftermarket amplifier. In Maestro Mode, a compatible vehicle-specific T-harness is added to enable full factory system integration with CANbus control.
Multiple Input Options: Four balanced differential RCA inputs, four high-level inputs with signal-sense turn-on, two auxiliary RCA inputs, and an SPDIF coaxial digital input provide complete flexibility for any installation scenario.
Eight RCA Outputs: Eight individual RCA outputs at up to 4V RMS support multi-amplifier configurations for front, rear, subwoofer, and spare channel assignments.
DSM Circuit Technology: 1% tight-tolerance components improve circuit efficiency, reduce crosstalk between discrete components, and lower operating temperature for long-term reliability.
Optional PLC2 Level Controller: The optional PLC2 remote controller adds physical level adjustment with assignable functions, providing a convenient dash-mounted control point without opening the app.
CE and FCC Compliant: Fulfils all essential safety and environmental requirements under the European Directives and FCC regulations.

Frequently Asked Questions
What is the difference between Universal Mode and Maestro Mode on the DSR1?
In Universal Mode, the DSR1 operates as a standalone 8-channel DSP using RCA or high-level inputs from any head unit and feeds signal to aftermarket amplifiers. No vehicle-specific harness is needed. In Maestro Mode, a compatible iDatalink T-harness is added and the built-in Maestro module is flashed with vehicle-specific firmware, allowing the DSR1 to intercept the factory CANbus audio signal and preserve OEM controls, features, and source unit functionality while replacing the factory amplifier and speaker signal chain entirely.
Does the DSR1 replace the factory amplifier?
Yes, in Maestro Mode with a compatible harness, the DSR1 replaces the factory amplifier by tapping the factory source unit's full-range, flat audio signal before it reaches the OEM amplifier stage. This bypasses factory equalisation and compression, giving the DSR1 a clean signal to process and distribute to aftermarket amplifiers. Universal Mode also supports factory amplifier replacement using high-level inputs with signal-sense turn-on, without requiring a Maestro harness.
What app is used to tune the DSR1, and which devices are supported?
The DSR1 is tuned using Rockford Fosgate's PerfectTune app, available on the App Store and Google Play. It is compatible with Apple devices running iOS 10.0 or later, including iPhone, iPad, and iPod touch, and Android devices running Oreo 8.0 or later, optimised for screens 5 inches or larger. Connection is via Bluetooth 4.0, which is used for tuning only and does not stream audio.
How many bands of EQ does the DSR1 provide, and how are they distributed?
The DSR1 provides 245 total bands of parametric EQ, with 31 bands per channel across four channel groups: Front, Rear, Spare, and Subwoofer. Each band offers selectable Q from 0.01 to 10.0 for precise frequency shaping. Combined with variable crossovers (20 Hz to 10 kHz, up to 48 dB/octave slope) and up to 10 milliseconds of per-channel time alignment delay, the DSR1 provides a professional-level tuning toolkit for correcting factory acoustic deficiencies.
Can the DSR1 be used without a Maestro T-harness?
Yes. In Universal Mode, the DSR1 operates with standard RCA inputs (up to 4V), high-level speaker inputs (up to 12.5V) with automatic signal-sense turn-on, auxiliary RCA inputs, or SPDIF coaxial digital input, and works with any aftermarket amplifier configuration. A Maestro T-harness is only required when integrating with a factory-amplified OEM system in Maestro Mode.

RATS tested for quality and performance and optimised using the AudioGraph PowerCube measurement tool.
Features & Benefits
Full-Range Class-D - Efficient 2-Channel Marine Amplification: Full-Range Class-D topology delivers high-efficiency power across the complete 20Hz-20kHz audio spectrum, reducing current demand on the vessel's electrical system compared to traditional Class-A/B designs while powering marine speakers with clean, accurate output.
Bridgeable to 200W Mono: The M2-200X2 can be bridged to a single mono channel delivering 200W x 1 at 4-ohm (215W dynamic), making it usable as a subwoofer amplifier in smaller builds or as a dedicated mono driver for a single full-range speaker pair in more compact marine audio systems.
C.L.E.A.N. Technology - Precision Gain Calibration: C.L.E.A.N. (Calibrated Level Eliminates Audible Noise) is a patented circuit with dedicated input and output clip indicator LEDs, enabling precise gain calibration at setup to maximise output while minimising distortion.
Fully Adjustable Crossovers with All-Pass Mode: Both high-pass and low-pass crossovers are fully adjustable from 50Hz to 250Hz at 12dB/octave Butterworth, with an all-pass mode for full-bandwidth output when no crossover filtering is needed. A variable infrasonic filter from 50Hz to 250Hz is also available for additional low-frequency protection.
RCA Pass-Thru Outputs for Downstream Chaining: RCA pass-thru outputs are active with both RCA and high-level input, allowing the signal to be passed to an additional amplifier - such as the M2-500X1 subwoofer amplifier - without signal degradation.
Auto-Sense Turn-On with RAP Bypass: Auto-Sense activates the amplifier automatically when a high-level input signal is detected, removing the need for a dedicated remote turn-on wire. A bypass switch is included for vessels with Retained Accessory Power (RAP) systems to prevent the amplifier from remaining on after the ignition is switched off.
NOMAD, MEHSA4, and Conformal Coated Circuit Board: NOMAD provides real-time protection against shorted speaker wires and dangerously low impedances. MEHSA4 (Maximum Efficiency Heat Sink Application) reduces MOSFET temperatures, lowers distortion, and extends output device life. The conformal coated circuit board protects the electronics against dust and water ingress at the PCB level.

Frequently Asked Questions
What is the difference between the M2-200X2 and the M5-800X4?
The M2-200X2 is a 2-channel full-range Class-D marine amplifier rated at 100W x 2 at 2-ohm from the M2 Element Ready series, designed for accessible, space-efficient marine speaker amplification. The M5-800X4 is a 4-channel Class-AD marine amplifier rated at 100W x 4 at 2-ohm from the premium M5 series, adding two additional channels, IPX6 water intrusion rating, Punch EQ2, the PRESET feature, and significantly more installation flexibility. Choose the M2-200X2 for a compact, economical 2-channel solution; choose the M5-800X4 for a 4-channel build with premium marine protection.
Can the M2-200X2 be used to power a subwoofer?
Yes, when bridged to mono. In bridged mode the M2-200X2 delivers 200W x 1 at 4-ohm (215W dynamic), which is sufficient to drive a single 4-ohm marine subwoofer at moderate output levels. For dedicated subwoofer amplification with more power and a tunable Punch EQ, the M2-500X1 is the recommended companion amplifier. The M2-200X2's RCA pass-thru outputs allow it to chain directly to the M2-500X1 in a two-amplifier system.
Does the M2-200X2 need a dedicated remote turn-on wire?
Not necessarily. The Auto-Sense feature activates the amplifier automatically when it detects a high-level (speaker) input signal from the source unit, removing the need for a separate remote wire. A RAP bypass switch is also included for vessels where the source unit continues to output a speaker signal after the ignition is switched off, preventing the amplifier from remaining on unintentionally.
What crossover options are available on the M2-200X2?
The M2-200X2 offers a fully adjustable high-pass crossover, a fully adjustable low-pass crossover, and an all-pass mode, all using 12dB/octave Butterworth slopes adjustable from 50Hz to 250Hz. A variable infrasonic filter is also available. This makes it suitable for use as a speaker amplifier in all-pass mode, a high-passed mid-range amplifier, or in bridged mono as a low-passed subwoofer amplifier, depending on the system configuration.
What fuse does the M2-200X2 require and is it included?
The M2-200X2 requires a 30A fuse. The fuse is not included in the box and must be sourced separately. Install the fuse as close to the battery as possible in the 4 AWG power supply line. Note that the 30A fuse requirement is significantly lower than the 80A required by the M2-500X1, reflecting the M2-200X2's lower current draw of 18A maximum.Legendary Products & Support From Authorized Dealers

Features & Benefits
Class-AD — Class-A Sound Quality with Class-D Efficiency — Class-A amplifiers are widely regarded for their linearity and low distortion but are thermally inefficient and physically large. Class-D amplifiers are highly efficient but have historically made compromises in audio quality. Rockford Fosgate's Class-AD combines the sonic characteristics of Class-A operation with the power efficiency of Class-D — delivering high-fidelity full-range amplification in a format suited to demanding car audio installations.
Dynamic Switching Frequency Control — A proprietary technique that dynamically adjusts the amplifier's internal switching frequency to optimise linearity and minimise switching-related artefacts — contributing to the Class-AD's high-fidelity performance across the full audio frequency range. This is the technical mechanism that distinguishes Class-AD's audio quality from standard Class-D designs.
Constant Power — Optimised Output Across Impedances — The Constant Power circuitry maintains optimised output across a range of speaker impedance loads — providing consistent performance whether 4Ω or 2Ω speakers are connected, without the significant power variation seen in standard amplifier designs at different load impedances.
1,000W 4-Channel Full-Range Configuration — 250W per channel (total rated — confirm per-channel at specific impedance from the official datasheet) across four full-range channels. Designed for high-output front and rear speaker systems where component speakers or full-range coaxials require substantial clean power to achieve their performance potential.
RCA Pass-Thru Outputs — Signal pass-through allows the headunit RCA signal to be looped to a downstream amplifier — enabling the T1000-4AD to drive four speaker channels while simultaneously feeding a dedicated subwoofer amplifier for a complete multi-amplifier system.
24dB/Octave Crossover — Steep crossover slope for precise frequency band management — enabling high-pass filtering on front and rear speakers and the option to configure rear channels for subwoofer use in mixed speaker/subwoofer builds.
2/4 Channel Input Switch — Accepts either a 2-channel stereo input (internally distributed to all four outputs) or discrete 4-channel front and rear RCA inputs — accommodating both 2-channel and 4-channel headunit preamp configurations.
MOSFET Power Supply and Output Stage — MOSFET implementation across both supply and output stages supports the high-current, low-noise delivery required for Class-AD's high-fidelity operation.

Frequently Asked Questions
What does Class-AD mean and why does it matter for full-range speakers?
Class-AD combines the sound quality characteristics of Class-A amplification with the power efficiency of Class-D. Class-A designs are highly linear and produce very low distortion but are thermally inefficient. Class-D is efficient but involves switching-based operation that can introduce artefacts. Rockford Fosgate's Class-AD and its dynamic switching frequency control aim to deliver high-fidelity full-range performance with efficient power delivery — a meaningful advantage for component speaker systems that operate across the full 20Hz–20kHz range.
What is dynamic switching frequency control?
Dynamic switching frequency control is a technique where the amplifier dynamically adjusts its internal switching frequency based on the signal being amplified. This optimises linearity at each operating point, reducing the audible by-products of switching-mode amplification — contributing to the Class-AD's high-fidelity performance compared to standard fixed-frequency Class-D designs.
What is the confirmed per-channel power output of the T1000-4AD?
The total rated power is 1,000W across four channels. Per-channel power at 2Ω and 4Ω is not confirmed in the supplier data — pull the official Rockford Fosgate T1000-4AD datasheet for the full power specification table, including per-channel RMS at each impedance.
How does the T1000-4AD differ from the T600-4?
The T1000-4AD delivers 1,000W total (vs the T600-4's 600W), uses Rockford Fosgate's Class-AD technology with dynamic switching frequency control, and is specifically designed for high-fidelity full-range use. Both include RCA pass-thru. The T600-4 uses a conventional MOSFET design. For audiophile-oriented builds where audio quality is the priority, the T1000-4AD is the appropriate choice.
Is the T1000-4AD suitable for running subwoofers on the rear channels?
Yes. The 24dB/octave crossover allows the rear channels to be configured in low-pass mode for subwoofer use. However, the T1000-4AD's primary design intent is high-fidelity full-range speaker amplification via Class-AD technology — for dedicated subwoofer channels, a Class-BD mono amplifier (T1000-1BDCP, T1500-1BDCP, T2500-1BDCP) connected via the RCA pass-thru is the more appropriate and more powerful solution.

Features & Benefits
C.L.E.A.N. Technology (Patent 8,712,066): Rockford Fosgate's patented Calibrated Level Eliminates Audible Noise circuit uses dedicated input and output clip LEDs (C.L.E.A.N. IN Red, C.L.E.A.N. OUT Blue/Red) to accurately match the source unit's output to the amplifier's input sensitivity, removing distortion before it reaches the subwoofer.
P.O.W.E.R. Supply: Onboard power supply design that continues to generate output above the rated RMS figure as vehicle voltage increases, so real-world performance scales beyond the spec sheet across the 9-16V operating range.
Integrated Punch EQ: Continuously variable onboard bass equaliser providing 0 to +18 dB of boost at 45 Hz, correcting for acoustic deficiencies in the listening environment and delivering up to 3x the perceived bass without an external processor.
Variable Infrasonic Filter: Adjustable high-pass filter operating from 15 to 40 Hz at 12 dB/octave Butterworth, removing subsonic frequencies that can damage a subwoofer's voice coil and excursion limits without contributing audible bass output.
MEHSA 4 (Maximum Efficiency Heat Sink Application): Advanced thermal management system that reduces MOSFET operating temperatures, lowers distortion levels, increases overall durability, and extends the lifespan of output devices under sustained use.
Rollback Protection: During demanding musical conditions, the amplifier dynamically reduces power demand to prevent stress on output devices, preserving both the amplifier and the connected subwoofer under real-world listening conditions.
NOMAD Protection: A real-time analogue computer that continuously monitors the amplifier's speaker outputs and protects against shorted speaker wires and dangerously low speaker impedances, providing active fault management rather than passive fusing alone.
Balanced Differential Inputs: Differential input topology eliminates noise picked up by signal cables between the source unit and amplifier, delivering a cleaner signal into the amplifier stage.
Includes RLC Remote Level Control: A remote level control is included in the box, allowing bass output to be adjusted from the driver's seat without accessing the amplifier directly.
High Level Input Capable: Accepts both low-level RCA (150mV-4V) and high-level speaker signals (450mV-12V), making integration with factory head units straightforward.
Auto-Sense RAP Bypass: Auto-Sense bypass switch supports vehicles with Retained Accessory Power (RAP), allowing the amplifier to power on and off correctly using speaker-level signal detection without requiring a dedicated remote turn-on wire.
RCA Pass-Through Outputs: 2-channel RCA pass-through remains active with both RCA and high-level inputs, allowing an additional amplifier to be added downstream without splitting cables at the head unit.
CTA-2006 and CE Compliant: All power ratings verified at 14.4V with 1% or less THD to CTA-2006 industry standards, with no inflated peak figures used anywhere in the specifications.

Goes Well With
The R2-250X1 pairs naturally with Rockford Fosgate Prime R1 and R2 subwoofers, including the R1S410, R1S412, R2SD2-12, and R2D2-12, giving it a matched system from a single brand. A 4-gauge amplifier wiring kit is required for power and ground runs, and 8-gauge cable is needed for the speaker output. A quality pair of RCA interconnects is recommended for clean signal transfer from the head unit. For systems requiring additional channels for front and rear speakers, the R2-250X1 pairs directly with the R2-300X4 using the onboard RCA pass-through.
Frequently Asked Questions
What is the R2-250X1 designed for, and can it power full-range speakers?
The R2-250X1 is a dedicated monoblock amplifier designed specifically for subwoofer applications. Its frequency response is limited to 20-250 Hz and its crossover controls are Low-Pass and Infrasonic only, making it unsuitable for powering full-range or component speakers. For full-range speaker channels, a separate 4-channel amplifier such as the R2-300X4 is required.
What does the Infrasonic Filter do, and why is it important for a subwoofer?
The variable Infrasonic Filter removes subsonic frequencies below 15-40 Hz (adjustable) that are inaudible to the human ear but cause excessive cone excursion in a subwoofer. Without this filter, ported subwoofer enclosures in particular can be damaged by these frequencies at high power. Setting the filter appropriately extends subwoofer lifespan and allows the amplifier to focus available power within the audible bass range.
Does the R2-250X1 include a remote bass control, and how does it work?
Yes. An RLC Remote Level Control is included in the box. It connects to the remote level control input on the amplifier and allows the driver to adjust bass output level from a convenient dash-mounted position without accessing the amplifier. This is particularly useful when the amplifier is installed in a boot or under a seat.
What does Rollback Protection do?
During sustained high-demand listening conditions, Rollback Protection dynamically reduces the amplifier's power output to prevent thermal stress on the output devices. Rather than shutting the amplifier down entirely, it maintains audio playback at a reduced level, protecting the amplifier and connected subwoofer while keeping the system running.
What gauge wire is required, and is the fuse included?
The R2-250X1 requires 4 AWG power and ground wire and 8 AWG speaker wire, both using the onboard compression terminal block connectors. The recommended 50A fuse is not included in the box and must be sourced separately. The fuse should be installed in the power cable as close to the battery as possible.
