Interesting topic.
Once you get the JBL system dialed in, it sounds pretty wicked. My 08 SE V6's six-disc changer system has had no problems so far except for a CD single that got stuck in there once because it was a bit warped; but that wasn't the fault of the system, of course. The JBL option was one of the must-have options for me when I chose the SE, along with the leather. The system pounds pretty hard for a stock set up, and like others have said, if you keep that bass control up too high past 0 or 1, the car rattles like Britney Spears havin' an orgasm after I fucked her (yeah...she's a virgin alright)

but my settings of BASS: 1 MID: 2 TREBLE: 3 and fader and balance both at zero for the CD input, my discs sound great. I had a huge dual 15" Rockford sub box in my last car, a '99 Accord coupe, and I'm kind of over the whole bass-to-blow-your-sister's-dress-off scene...I love the JBL system in my SE.
