What's wrong?

The radio and speaker system in affected 2023-2025 Atc trailers is meant to play audio at normal cabin temperatures without heating the surrounding trim or speaker hardware. These trailers have an MB Quart radio and low-profile MB Quart speakers, and the radio sends the audio signal that drives the speakers.

The problem is inside the radio's internal programming. That software error lets the back side of the radio get hotter than designed, with Atc's investigation finding temperatures over 200 degrees. The heat transfers through the audio system and damages the speakers, which led to melted speaker material in the recalled trailers. The software update lowers the heat produced by the radio to 140 degrees, and damaged or melted speakers are replaced.

Owners can notice distorted audio, speakers that sound blown, a radio that feels hot to the touch, or visible melting around the speakers. Those signs mean the radio and speaker system needs recall service.

Who's affected?

Covers RM, PL, ST, and PR trailer lines from 2023-2025, all using the same MB Quart low profile speaker.

At the dealer, an Atc technician applies the Maxxsonics software update using the mailed USB instructions, then inspects the speakers and replaces any speaker that needs replacement. The recall repair is free, including the update, inspection, replacement parts, and labor.
