Ok so today when I turned my music on i realized my speakers on the driver side door and in the back were playing very low, so low you can barely hear it. I checked to see if everything was set right and it was. This is for the pioneer system by the way. When i put all the volume on the two speakers it is very very low and then when I switch it back to the passenger side it is loud and the bass hits. Do you think both speakers are blown?

 

if its stock then take it to the dealer. theres too many variables that it could be so without a complete overhaul thats going to be the cheapest best thing to do (assuming u have warranty)

 

if they were blown they would sound more of less like ****. not sure what it could be though
