One Amp to Rule Them All – Memphis Audio PRX800.5V2 5-Channel Power Reference Series Amplifier
Introduction
The Memphis Audio PRX800.5V2 is the ultimate all-in-one 5-channel amplifier, purpose-built to power your entire sound system from a single, compact chassis. Whether you're running a full set of mids and highs with a dedicated subwoofer or upgrading a factory system, this Class D powerhouse delivers clean, efficient sound with reliable daily performance. With plenty of tuning options, excellent output, and Memphis Audio’s trusted engineering, the PRX800.5V2 is your one-stop solution for big, balanced sound in any vehicle.
Full-System Power in One Chassis
The PRX800.5V2 provides 75W x 4 to your mids and highs, and up to 400W x 1 to your subwoofer at 2 ohms — making it a perfect fit for complete aftermarket systems. It eliminates the need for multiple amps, streamlining your build and saving valuable install space. You’ll enjoy crisp highs, punchy mids, and deep, controlled bass — all with the consistency and control of a Memphis-designed amplifier.
Class D Efficiency for Cool, Clean Output
Thanks to its Class D full-range architecture, the PRX800.5V2 runs cooler and draws less current than traditional Class AB amps. This makes it ideal for installs in tight spaces or behind panels where heat management matters. Despite its compact footprint, it delivers dynamic sound with minimal distortion and maximum impact — perfect for high-output systems in cars, trucks, and SUVs.
All the Tuning You Need, Right on the Amp
Each set of channels comes with its own adjustable crossovers for precise control. The front and rear channels feature high-pass filters (40–400 Hz), while the subwoofer channel includes a low-pass filter (40–250 Hz), bass boost (0–12 dB @ 45 Hz), and a subsonic filter for protecting your low-end driver from ultra-low frequency damage. The included remote bass knob gives you real-time control over subwoofer output from the front seat.
Streamlined Install with Premium Styling
The PRX800.5V2’s compact and stylish chassis includes Memphis Audio’s signature blue LED accent lighting, oversized power terminals, and a durable, matte black housing. Whether you’re building a stealth system or showing it off, this amp looks just as sharp as it sounds. Its small size also makes it easy to install under seats, behind panels, or in trunk sidewalls — wherever space is tight.
