Humming noise from front doors
Hi I recently upgrade my entire 2009 Honda Accord w/ NAVi sound system. I got an FM transmitted iPod adapter that hooks into a wire for better sound quality, a 1100W amp, two 6.5" component speakers in the front, two 6x9 speakers in the back, a 12" PB Subwoofer, and had 3 SNIs installed to transmit the signal from the stock head unit to RCAs to go to the amp. The SNIs are located under the dashboard on the passenger side. When I got my car back, I noticed a buzzing sound coming from the back two speakers that sounded like if you left a guitar amp only partially plugged in and humming noise that came in waves of two in the form of a quick crescendo. The humming happens when I idle at any speed and when I am decelerating and come to a stop. I brought my car to the audio shop that did the system and they moved the SNIs away from the fuse box underneath the dashboard and most of the buzzing stopped but the humming continued and was even a little worse? Could it be a bad connection job in the door speaker(s)? Or the FM transmitted iPod adapter? Or just a shoddy job at connecting the whole car? Any help is greatly appreciated.
