Trouble with the Thompson Family Car Stereo

We have a twelve year old car. Repairs are part of the game, but I am not interested in learning to fix my own car. When the neutral switch went, I did not crack the manual. When the flex joint was leaking exhaust, I did not google "how to weld new flex joint in 2003 Passat." This is an area where I happily pay my mechanic for his expertise. But, you guys, the car stereo is broken. The driver's side woofer is blown, I assume, as I could hear no low end in Black Sabbath's Paranoid, which was this week's CD of choice for toting kids around Brooklyn. (Come on, of course they love "Iron Man!")

What am I going to do? I can't really justify replacing the speakers in my senior citizen Passat, but I cannot drive around town listening to tinny albums. This may compel me to learn a few car repair skills after all. To be continued...
