Prime Marine 600 Watt 5-Channel Amplifier

The M600-5 is a 600 watt marine grade “all-in-one” amplifier featuring four full-range stereo channels and a dedicated mono subwoofer channel.





The Prime M600-5 is a 600 Watt amplifier specifically designed for Marine and Motorsport applications through its 2-part epoxy coated Printed Circuit Board (PCB). The four stereo channels feature Class-A/B topology and the dedicated subwoofer channel runs on high efficiency Class-D. High level and low-level RCA inputs allow for flexibility and the on-board Punch EQ, built-in 12dB crossovers, and independent gain controls permit precise tuning. Real time output and thermal sensing along with current and short circuit protection protect the amplifier under adverse conditions.
