Rockford Fosgate R2-300X4 Prime 300 Watt 4-Channel Class D Amplifier When four speakers need real power without compromise, the R2-300X4 delivers 300 watts of clean, efficient Class D performance engineered by Rockford Fosgate. Product Overview The R2-300X4 is part of Rockford Fosgate's 3rd generation Prime Series, built for car audio enthusiasts who demand reliable, high-performance amplification at an accessible price. Operating as a full-range Class D 4-channel amplifier, it runs at 4 ohm or 2 ohm stereo and 4 ohm bridged/mono, giving it the flexibility to drive front and rear speaker pairs or reconfigure as a 3-channel or 2-channel setup. Class D topology maximises efficiency and reduces the electrical load on the vehicle's charging system, while MEHSA 4 (Maximum Efficiency Heat Sink Application) actively reduces MOSFET temperatures, lowers distortion, and prolongs output device lifespan. The top-mounted control panel provides independent front and rear controls within easy reach, and CTA-2006 compliant power ratings confirm that the 300W output is a real, tested figure. Designed and engineered in Tempe, Arizona, the R2-300X4 is built by fanatics, for fanatics. 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 for both front and rear) to accurately match the source unit's output to the amplifier's input sensitivity, eliminating guesswork and reducing distortion at the source. 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. MEHSA 4 (Maximum Efficiency Heat Sink Application): An 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. NOMAD Protection: A real-time analogue computer that continuously monitors the amplifier's outputs and protects against shorting 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. Fully Adjustable Butterworth Crossovers: Independent front and rear 12 dB/octave High-Pass and Low-Pass crossovers, continuously variable from 50 to 250 Hz, with an All-Pass option per channel for full-range output when no filtering is needed. High Level Input Capable: Accepts both low-level RCA (150mV-4V) and high-level speaker signals (450mV-12V) through a 2/4 Channel Input Selection Switch, 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 downstream amplifiers to be added 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.

For systems requiring low-end support, the rear channels bridge cleanly to drive a single Prime R1 subwoofer such as the R1S410 or R1S412, with the rear crossover set to Low-Pass. A 4-gauge amplifier wiring kit is required for power and ground runs, and 8-gauge cable is needed for speaker outputs. A quality 4-channel RCA interconnect is recommended for clean signal transfer from the head unit. Frequently Asked Questions Can the R2-300X4 be used to power both speakers and a subwoofer in the same system? Yes. The R2-300X4 supports 3-channel configuration, where the front channels power a pair of full-range speakers and the rear channels are bridged to drive a single subwoofer. Setting the rear crossover to Low-Pass rolls off high frequencies to the sub. The minimum impedance of any bridged channel is 4 ohms, so confirm subwoofer impedance before bridging. Does the R2-300X4 require a remote turn-on wire? When using RCA inputs, a remote turn-on wire must be connected to the head unit's remote output. When using high-level speaker inputs, the Auto-Sense bypass switch can be enabled to allow the amplifier to detect an incoming signal and power on automatically, making it compatible with factory head units and systems that lack a dedicated remote output, including those with Retained Accessory Power (RAP). What does the NOMAD protection system do? NOMAD is a real-time analogue computer built into the R2-300X4 that continuously monitors the amplifier's speaker outputs. It protects the amplifier from damage caused by shorted speaker wires and dangerously low speaker impedances, providing active, dynamic protection rather than relying solely on a fuse. What gauge power, ground, and speaker wire does the R2-300X4 require? Rockford Fosgate specifies 4 AWG for power and ground runs using the included compression terminal block connectors. Speaker output connections use 8 AWG wire. The recommended 60A fuse is not included in the box and must be sourced separately, installed as close to the battery as possible. Can the R2-300X4 be bridged into a 2-ohm load for maximum power? No. When bridging the R2-300X4, the minimum supported impedance per bridged output is 4 ohms. Running a bridged channel into a 2-ohm load is not supported and risks amplifier failure or NOMAD-triggered protection shutdown. In standard stereo mode, the minimum impedance per channel is 2 ohms.Legendary Products & Support From Authorized Dealers When you choose Frankies BrandBeast, you're choosing quality and performance.

The R2-500X4 is a 4-channel full-range amplifier rated at 125W x 4 at 2-ohm with no dedicated subwoofer channel, no Punch EQ, and no remote level control. The R2-750X5 is a 5-channel amplifier rated at 100W x 4 plus 350W subwoofer at 2-ohm, adding a dedicated subwoofer channel with Punch EQ, infrasonic filter, RLC remote level control, and a 2/4/5 channel input switch. Choose the R2-500X4 for a pure 4-channel speaker amplifier and pair it with the R2-750X1 for subwoofer duty; choose the R2-750X5 for a single-unit 5-channel solution. Can I add a subwoofer amplifier to a system using the R2-500X4? Yes. The R2-500X4 includes RCA pass-through outputs that are active with both RCA and high-level input, allowing a distortion-free signal to be passed to a downstream mono subwoofer amplifier such as the R2-750X1. The two amplifiers chain together cleanly for a complete 4-channel speaker plus mono subwoofer car audio system. What does the 2/4 channel input selection switch do? The input selection switch configures the R2-500X4 to accept either a 2-channel or 4-channel input from the source unit, working for both RCA and high-level connections. In 2-channel mode, the single stereo RCA pair feeds all four channels internally. In 4-channel mode, separate front and rear RCA pairs are used for independent left/right front and rear channel control. What fuse does the R2-500X4 require and is it included? The R2-500X4 requires an 80A fuse, which is not included and must be sourced separately. This is smaller than the 120A fuse required by the R2-750X5 and R2-750X1, reflecting the R2-500X4's lower maximum current draw of 59A. Install the fuse as close to the battery as possible in the 4 AWG power supply line. Does the R2-500X4 need a dedicated remote turn-on wire? Not necessarily. Auto-Sense activates the amplifier automatically when a high-level speaker signal is detected at the input, removing the need for a separate remote wire in OEM integration scenarios. A RAP bypass switch is included for vehicles where the source unit continues to output a signal after the ignition is switched off.Legendary Products & Support From Authorized Dealers When you choose Frankies BrandBeast, you're choosing quality and performance.

The MX280/4 provides four independent channels (70W each) ideal for front/rear speaker configurations or multi-zone systems, while the MX600/3 provides two speaker channels plus a dedicated high-power subwoofer channel. Choose the MX280/4 when you need four separate speaker zones without a subwoofer, or when you plan to add a separate monoblock for subwoofer duties. Choose the MX600/3 for integrated speaker and subwoofer amplification in one unit. The MX280/4 is also smaller and requires lighter wiring (8 AWG vs 4 AWG). Can I bridge channels to power tower speakers or a subwoofer? Yes, bridge channels in pairs to create two 140-watt outputs at 4 ohms. This is perfect for powering two large tower speakers (bridge Ch 1-2 and Ch 3-4), or bridge one pair for a subwoofer while using the remaining two channels for full-range speakers. When bridging, connect positive to one channel and negative to the adjacent channel, ensuring 4-ohm minimum load per bridged pair. What makes IPX7 rating critical for marine and powersports applications? IPX7 certification means the amplifier survives complete submersion in 1 meter of water for 30 minutes, not just light splashing. This is essential for installations in open boats, personal watercraft, jet skis, or UTVs where the amplifier may be fully exposed to waves, heavy rain, pressure washers during cleaning, or accidental submersion. Standard amplifiers with lower IP ratings will fail in these conditions, while the MX280/4 continues operating reliably. Why would I choose the MX280/4 over a standard car amplifier for my boat? The IPX7 waterproofing is the primary advantage, along with marine-grade corrosion-resistant construction designed for saltwater environments. The ultra-compact size (8.66" x 1.77" x 3.09") enables installation in locations where standard amplifiers won't fit. The pigtail connection design with no exposed terminals maintains waterproof integrity. Standard car amplifiers lack waterproofing, corrode rapidly in marine environments, and typically require significantly more mounting space. How do the switchable channel input modes work and what configurations are possible? The input mode switch configures how signals feed the amplifier. In 2-channel mode, the front input pair feeds all four channels (ideal for stereo sources). In 3-channel mode, typically used with front/rear/sub source outputs. In 4-channel mode, each input pair feeds its corresponding amplifier channels independently for maximum flexibility with 4-channel source units. This flexibility accommodates various head unit configurations without requiring external summing devices or Y-adapters.Legendary Products & Support From Authorized Dealers When you choose Frankies BrandBeast, you're choosing quality and performance.

Frequently Asked Questions Can I install the DEQ-2000A without removing my factory stereo? Absolutely! The DEQ-2000A is specifically designed to work with your factory head unit using speaker-level inputs. It processes the signal from your existing stereo and upgrades the sound quality without requiring any replacement of factory components. Optional speaker line input cables make installation even easier. Do I need professional installation, or can I install it myself? While professional installation ensures optimal results, the DEQ-2000A is designed for ease of installation with its compact size (fits under most seats) and flexible input options. Basic car audio installation experience is helpful, but the included documentation and online resources make DIY installation achievable for enthusiasts with moderate technical skills. How do I tune the DSP - is it complicated? Not at all! The free DSP Controller app provides an intuitive visual interface on your smartphone (iOS or Android) that makes tuning straightforward. You can use pre-set EQ curves matched to common vehicle types, then fine-tune while listening. For more detailed control, the PC software displays all functions on one screen for professional-level adjustments. Will this work with my Apple CarPlay or Android Auto? Yes! The DEQ-2000A is fully compatible with both Apple CarPlay and Android Auto systems. It processes audio from these sources seamlessly while maintaining factory navigation audio mixing, so GPS voice guidance automatically attenuates music without interrupting your connection. Can I add a subwoofer to my factory system with this DSP? Definitely! The channel summing feature allows you to create a dedicated subwoofer output by combining channels, even from a factory stereo signal. With 6 RCA pre-outs, you can easily connect a subwoofer amplifier and integrate bass into your system with proper crossover settings and time alignment. What's the difference between this and just adding an amplifier? A standard amplifier only increases power. The DEQ-2000A is a complete audio processor that corrects acoustic problems in your vehicle through time alignment (compensates for speaker positioning), equalizer (corrects frequency response), and crossover management - PLUS it includes 160W of amplification. It's the "brain" that makes your entire system sound dramatically better. How much power does the built-in amplifier provide? The DEQ-2000A delivers 160W nominal power (4 x 40W per channel) with 320W maximum power output. This is sufficient to drive factory or aftermarket speakers directly, or you can use the 6 pre-outs to connect external amplifiers for higher power applications while still benefiting from the DSP processing.
