i have the same problem with ML in my GX when it was under factory warranty, door rattled from speaker, took it to dealer, they called lexus rep, lexus rep told me tuff ****, ain't nothing we, it's not the speaker its the door rattling - same goes for cracked leather in driver seat, lexus rep refused to fix it and i used lexus leather conditioner - so much for full factory warranty.

 

no, haven't tried that yet,,,, it's worth a try.

 

Lexus and Audi do seem to have this problem.
My brother has a 2008 e93 335 with Logic 7 speakers and they are NICE.
Great mid range speakers with a lot of potential of low end without rattles
BMW did build that car very well because we often blast the speakers going convertible and with the subs nearly all the way up, no rattles after 3 years of owning it

 

yeah, i wouldnt even think of streaming via bluetooth in my cars due to bad quality, just plug in the cable and you get perfect digital connection + you recharge your phone... and we all know how much our smartphones need recharging anyway.
