one dash speaker not working
 

Hello guys and gals. I am new to this site and hope you can solve a problem I have. My car is a 1998 Boxster that we purchased a year ago. My left dash speaker doesn't work. I put the right speaker on the left side and it did work. Do you think it is the speaker or I see there is a small transistor connected to the speaker. Could that be bad? If I bypass the transistor should it work?
