My door panel vibrates/buzzes when I turn the Bose stereo volume up over about 11. No matter how high I turn the volume, you can hear the door vibrate - makes the expense of going for the Bose kind of useless. Will Mazda fix this under warranty? I have about 1500 miles on the car.

 

Polak has a good DIY.
I don't know if I'd let Mazda mess with it...
... buy hey, thats me

 

go to a decent car audio and get dynamat put in it wont only get rid of the vibration but u will get alot better sound out of the whole system the cost shouldnt be over 100$ depends on how much u need they have premade door instalations for all sizes of speakers im sure 1 will fit in the 8

 

are you shure its the pannel. I had the same problem only to realize it was some loose change on the door pocket

 

I am sure its the panel. If I put my hand on the door panel under/behind armrest, I can stop the noise - plus side pocket was empty.

 

where is the bass set on your stereo. if it is above +1 or 2, try turning it down.

 

still shouldnt be a problem i have mine all the way up at volume 20-25 with no problem at all but i wouldnt bring it to the dealer to fix it i would just bring it to an audio place and pay the extra money for a more crisp sound

 

maybe, maybe not. If i turn the bass up over 4, it vibrates no matter what. but if i keep it at 3 or below, i can turn up the volume as high as id like with no vibrating. could just be my 8 though.

 

If the car is under a year old they should fit it but with Mazda who knows.

 

I'd say bring it in could be a lose screw or screws causing the problem. If they dont fix it just buy dynamat as someone said. Its on my own list of thigns to buy for the 8 its just huge though ugh!!

 

im not saying mazda wont fix it but do u really want them to fix it? if they do they will take it in for a week and when you bring it home something else will be broken i say bring it to an audio specialist and have it done right so u arent back at the dealer 3 times for the same problem i know its convenient to get it done free from mazda but quality > all.
