Hey guys my right rear speaker (Bose of coarse) is blown. And im getting like a vibration or like the sound is something loose on my front right. So my questions are.... Where should i go / look for a replacement Bose speaker? and what do u think could cause the front right to malfunction like so? Thanks in Advance!!!

 

First you should take a look at the speakers themselves. For the Bose rear shelf speakers the cone comes off (lotsa power) and sounds like the speaker is blown. Mine did that on my S4, took them out and re-glued the center cone back on and they sound like new again.
As for the front one you'll probably have to replace it. Dealer part im guessing.
