Introduction
The Memphis Audio MJP800.4 is a full-range, high-output 4-channel amplifier from the elite MOJO Pro Series, designed to power your mids and highs with incredible clarity and volume. Perfect for competition builds and loud daily drivers, this amp delivers dynamic output across four channels with precise tuning options and rugged construction. Whether you're feeding your pro-audio speakers or bridging power to push midbass drivers or towers, the MJP800.4 gives you full-system control and unmatched performance.
Loud and Clear Full-Range Power
The MJP800.4 pumps out an impressive 200 watts RMS per channel at 4 ohms, or a staggering 400 watts x 2 bridged at 4 ohms, making it ideal for driving pro-audio mids, compression horns, or coaxials at high volume. With clean, distortion-free output across the entire frequency range, this amp ensures that your vocals and instruments cut through with razor-sharp clarity — even when your system is wide open.
MOJO Pro Series Build for Serious Systems
As part of the MOJO Pro Series, the MJP800.4 is crafted using competition-grade internals and a sleek, thermally optimized chassis. Designed for intense output and long-term reliability, the amplifier features robust MOSFET power supply components, oversized output stages, and multiple onboard protection circuits to keep your system running strong under pressure. Whether you're pushing the limits in competition or daily flexing, this amp is built to dominate.
Flexible Configuration Options
With its multi-mode versatility, the MJP800.4 can be run in 4-channel, 3-channel, or bridged 2-channel mode, giving you complete freedom to configure your system your way. Use it to drive four pro-audio midrange drivers, two mids and two tweeters, or bridge it to power a pair of midbass monsters. It's tuned for full-range performance but also includes high-pass and low-pass filters for dialing in crossover points to match your speaker setup.
Precision Tuning for Peak Performance
The fully adjustable crossovers (50–250 Hz) let you fine-tune the output for each pair of channels, while the variable gain controls help you match input sensitivity with your head unit or DSP. This flexibility ensures that your system plays at peak efficiency without distortion or clipping — a must for serious audiophiles and competitive sound builders.
Built Tough with MOJO Styling
Wrapped in bold black and orange MOJO aesthetics, the MJP800.4 isn’t just about performance — it looks the part too. The compact design makes installation easy in a variety of custom setups, while its oversized terminals simplify wiring and ensure a solid connection in high-current systems.
