Conditions: Only Occurs when:
Brake is depressed
MS-8 volume is up: Muting MS-8 completely eliminates the noise (thus JL Amps are not the culprit so it's either an INPUT to the MS-8, or generated by MS-8 (note, the MS-8 also produces a processor/digital noise which I can hear but its not as bad.
I thought this problem was new since my JL HD amp install but realized that I'd heard it before when the cruise control applied the brakes (at that time still had the stereo coding and the JL XD600/6). When i correlated it to the brakes today, I had an aha! moment.
Any help? 6spdcoupe? VP Electricity? Technic? ....?
The only way that I can see something like this happening is by the ground connection point being shared between the MS-8 and the tailights.
The "buzz" is the tailights lighting up and the audio picking it up via a weak ground.
