I just got this installed at Car Toys and the back speakers make a bad vibration with any bass going through them. They're Pioneer speakers but it's not the speaker. I can feel it real good when I put my hand on the outside of the car where the speaker is. Is there anything I can do about this. It sucks right now. But the stereo is killer. Thanks.

I dunno if some foam pading around the speaker and behind it would help any. Might wanna try.

 

Slap some sound deadening material in the speaker well...should stop some if not all of your vibration. Assuming it's the body making the noise and not the speakers themselves.

 

I'll give that a try. That vibration is killing me. Thanks.

Also check the bracket(plate) that the 6x9 is mounted to and make sure the screws are tight. They tend to get loose over time. And as far as feeling the vibration on the outside of the car. Like someone stated above put some sound dampening material behind the 6x9's and that should help.

 

I have that exact same Stereo, and I had the exact same problem, But it's not the stereo it's just the speakers themselves.

I put a little bit of foam inbetween the back of the speaker and the panel. It killed about 99% of the problem!
