| I've been inside my B212s and the wiring is solid, including the speaker-terminal clips. Still, it'd be wise to pull the rear plate, get in there with a flashlight, and see what's going on. Should be obvious, as in maybe a wire connecting one speaker's (+) to its neighbor's (-) fell off (or is missing). If it's missing, check around the bottom of the cab. It's a five-minute job max. The plate screws come out easy with a hand screwdriver -- no power driver needed. |
