Re: Stock Head Unit Tweeter Buzz
sounds like interference or grounding problems. could also be wiring issues.
Trace your steps again and make sure all speakers are wired right and nothing is grounded out.
Also, if your stock speakers are not coaxial, then the sound might have been there the whole time, but your old speakers wherent able to reproduce the tone. If so, then it might also be a headunit problem.
