okay i had a problem a few weeks ago. was on a roadtrip and suddenly heard several loud bumps on the driver side door- almost sounded like something hitting the door. finally figured out it was an electrical popping in the speakers. I turned off the stereo and turned it back on an voila- problem gone. fast forawrd to last week. another road trip. got almost where i was going and the sound from the passenger side speakers just stopped.
right now here are the issues:
no radio or cd sound from any of the right side speakers
when you turn the car on you can hear motor noise buzzing from the right speakers
the buzzing in the right speakers occurs whether you have the stereo turned on or not
occasionally while listening to my one sided stereo i will here popping noises from the passenger side

from what i have read in some other posts on here it sounds like it could possibly be a bad amp

any advice will be appreciated!!
