(Background: through at least early 2015, the underseat subs were 2 ohms wired in parallel for Hi-Fi cars, and 8 ohms wired in series for HK cars.)
With how Technic wires these, I can very easily see ohm rating and wiring technique affecting the harness' operation -- particularly on parallel-wired setups that operate off a single output channel. I would email him and make him aware of the issue.

I have the HiFi system. m235i /2016. Drivers sub is not working, not the oem nor the bavsound.
