Stock Subwoofer issue - Help!

When I got my truck back from the dealership (rear spring TSB) I noticed today how weak the stereo sounded. It was gutless. It appears that the subwoofer is not pumping out anything. I noticed also that the level was at 5 and I generally keep it at 2-3. Is there something I can check (fuse, anything) before I call the dealership and ask them whatsup? I don't want to have to leave my truck for another day for them to check it out.

I realize that the stock system (JBL, Sub etc) is weak but it sounds fine to me for what it is and with treble at 3 mid at 2 and bass at 3 it pumps out enough for my blood.

Thanks for your help. I'm hoping to not have to drop it off and ask why some teenage pump cranked my system while taking it to the "free" carwash...

 

Thanks Whipper. I may pull it apart this weekend and see what's up. The JBL stereo blows, I know, but turn the bass down to -5 and it even worse. Hopefully it self rectifies so I don't have to take it to the dealer.

I'll eventually replace it as well. I too love the sound of clean music. I even have a 2 channel setup at home (NAD and B&W stuff) dedicated for CD's only (my wife hates it). Thus you can see the frustration I'm having.
