Overview

One amp. No compromises.

The Rockford Fosgate M5-1500X5 is a high-output 5-channel amplifier designed to run an entire system with serious power. This isn’t your basic all-in-one—this is for builds that actually demand output.

What It Is

A full-system, high-power 5-channel amplifier.

• 1500 watts total output
• 4 channels for speakers + 1 dedicated sub channel
