I just put in a pair a Pioneer TS-1674R's in my front doors. I've had a Pioneer DEH-6300UB. My right front speaker before had a weird vibration when deep bass kicked in, and was just plain dying. It was like that before I changed headunits too. Even with the new speaker, the vibration is still there and it still has some feedback even with there isn't deep and heavy bass. The left one doesn't have any problems.

Is it something with the wiring? What could the problem be?

Does it do it when it's not installed in the door? If not, then there is something loose in the door. If it does, switch speakers and try it again. If it still does it, then there is an issue with the wiring or that channel of the head unit.

you need to properly insulate it with dynamat. also you probably need to amp ur your speakers

I'll look into that today.

I pretty much figured that out. I'm just wondering why only one side.

Too expensive for me right now. Amp and sub(s) will be added in the spring, might have to pick up some sound dampening mat too.

You might have a loose screw/nut in the door panel
