I won't be so bold to say that I am an audiophile but.. I have a hi-def home theater with all the toys. I enjoy clean sound. The RF in my Titan is awesome (if you don't count the radio). The subwoofer is a perfect match. The only thing that I can think of is that there are assembly issues because I can't believe that some would find the sound to be crappy. I would go to the dealer for a second opinion on a different truck. Maybe I got lucky and got the perfectly tuned system.
IMO Bose is the most overrated system. If you do a side by side comparison you will see how "light" they are. I installed a set of Bose speakers in my Brother-in-laws house. He is so proud of those 4 letters on the speakers that he can't tell that they don't sound good. They have done a great job of making their name THE desired brand. The same reason that I went out to buy a Ram last December. Man I wanted a hemi.. Until I drove the Titan.
