alright my rx8 is by far the best car i have ever had. definitely the fast and most agile. but however the stereo system is going on 8 years old and its been buzzing since i got it last year. i already completely took the center speaker out so i could be sure it wasn't it. someone has replaced the stock amp with a new one and i figured they grounded it wrong so i tried that i even re-grounded my headlights because it gets louder when i drive at night. if anyone can help me please do

 

oh and i apologize if this is the wrong place for this but that sound is extremely annoying.

 

this should go in the audio or troubleshooting forum.
