Hey guys I have an 07 with factory speakers and head unit, I believe my front speakers are going out, the right side speaker has a very muzzled sound and the left side occasionally just goes out with no sound. I have also noticed that when listening to the radio I sometimes get it going in and out or a buzzing sound that drowns out music. My question is, is this a radio problem or a speaker problem. I know I need a new right speaker but do I just need to get a new front speakers or get a new head unit as well. When the sound is on the rear speakers the radio is fine.
