I bought a subwoofer from someone at their house, so we was talking this and that and I put the sub on the roof on my car literally on the side where side airbag would be and I notice the sub was magnetic and it got stuck a bit to the roof . So I turn on the car no light but a hour later the light came on? Anyone think the magnet interfered with the sensor in there ? I recently took the steering wheel airbag out to install leds in the control buttons couple months ago and never had light since then . So I hope it’s not the steering the problem . Any reply’s would be helpful thank you .
