[QUOTE="Lasherž, post: 8717342, member: 679555"] First thought is ANC (active noise canceling) feedback loop. What's the year, make, and model? We also need more details about your audio gear, specifically whether this was a new install before you started the car that day, whether you did the install, and how the gains were set. Also whether the subwoofer sounded healthy afterward or if it was playing notes above its normal range and having random spikes of volume? Given that it started when the car did and it changed with speed it's either power related or ANC related. [/QUOTE]
