One Amp That Runs Your Whole System

If you want a clean, simple setup that still hits hard, the Rockford Fosgate R2-750X5 is built exactly for that kind of build. This 5-channel full range Class D amplifier packs your front, rear, and subwoofer power into one compact chassis, so you do not need multiple amps cluttering your ride. With flexible 5-channel, 4-channel, or 3-channel configurations, it adapts easily whether you are building a full system or upgrading step by step. Add in CEA-2006 certified ratings, and you know the power you are getting is real, tested, and consistent.

Clean Power Across Every Speaker

What makes this amp stand out is how balanced and controlled the output feels across the entire system. You get 50W x 4 RMS for your full range speakers, strong bridged options when you want more output, and a dedicated sub channel pushing up to 350W RMS for solid low-end performance. The Class D architecture keeps everything efficient and cool while still delivering punchy, clean sound. With independent control for front, rear, and sub channels, you can fine-tune your entire soundstage exactly how you like it without guessing.

Built for Real Installs and Real Bass Control

This amplifier is also packed with tuning tools that make real-world setups way easier to dial in. Adjustable crossovers, variable infrasonic filtering, and Punch EQ bass boost give you full control over how your system responds, from tight mids to deep, controlled bass. The included remote sub level control lets you adjust bass on the fly from the driver seat, while auto turn-on support and multiple input options make installation flexible in almost any vehicle. With heavy-duty power terminals, RCA and speaker-level inputs, and smart mounting options, the R2-750X5 is built to drop in, tune up, and perform without hassle.

  • The CLEAN feature is a really a huge help to get the best audio possible from the amp and the speakers. I’m still waiting for the sub, so I can’t talk about the lows coming from the amp yet, But with the speakers, they really sound better now since I got this amp as an upgrade
