Hey guys I recently put my 6x9's in the back of my blazer until I can build a guard under the seats so the kids dont kick the speakers! But after I did I noticed a nasty buzz sound comming out of the left speaker, I looked around on the web and everyone points out grounding problems, but i dont think thats my problem here, its only out of one speaker, and the buzz doesnt get louder when i speed up, the buzz does get louder when i turn up the volume, I can hear it when i turn down the volume but i got to get closer to the speakers, whenever i press against the face of the speaker the buzz goes away completely, its just a bad vibration it looks like and its only out of that speaker... I checked the wires and they are connected properly and secure... Im not sure what to look for now! hopefully you guys can help me out because the noise is driving me insane!!!!!!!!!!!!!

 

sounds like the voice coil in the speaker is out of alignment. When you press down on certain areas of the cone it's being realigned. There may be someone locally to you that could repair it, but it may get close to the cost of replacing.
