Passenger rear speaker problems
 

Hey everyone! My passenger rear speaker stopped working x amount of days ago. (maybe even months) and so believing it was blown.... I went through the whole process of taking out the back seat and removing the speaker. I bought 2 brand new speakers. I. Immediately went for The "blown" one.. Come to find out... The new one won't work either.... Does anyone have any ideas on what's going on? =(
