M Harness (Module M / Speaker Extension)

The M Harness is designed to connect your CoxBox® system to the boat’s speakers, providing clear and reliable communication between the coxswain and crew. Built for durability in demanding on-water conditions, it ensures consistent audio performance during training sessions and race days. Compact and easy to install, the M Harness helps maintain a stable connection so every call from the coxswain is heard clearly.

The M Harness connects after the first section (either the A or A+ harness as the firs section). The M harness acts as an extension cord between speakers.
