Product Information

Old school power

Morel built this MPS 4.400 amplifier so their high-performing car speakers would have an amp worthy enough to power them, giving you high-fidelity musical reproduction along with pure, clean power. The MPS 4.400 can send 70 watts RMS to each of your front and rear speakers, boosting musical clarity and emotional impact. You can also set this amplifier to 2-channel mode and power a couple of subs with up to 200 watts RMS each.

Low-noise design

Morel made sure that every detail of this amplifier's design would result in lower noise and higher sound quality. The amp's Class AB architecture achieves the cleanest signal with the least distortion, while balanced differential inputs reject interference. An onboard microprocessor controls the thermal management system, keeping the amp running cool and steady no matter how hard it's driven. All the connections are on one side of the amp to keep wiring neat, organized, and simple for the installer.

Tone controls for every occasion

The high- and low-pass filters and gain controls sit protected under a top panel. Their intuitive operations and functions make it easy to match the amp's output to your speakers or subs — and achieve great sound. This amplifier's modest exterior shelters high-quality electronic components that guarantee an accurate and musical performance.
