Bose without Navigation Woofer?

[jimimonet]

I am taking the hatchback area apart to Dynamat it. I took the subwoofer out and since I am curious I took it apart. One question and one observation. How does the sound from the sub woofer get out, I mean there is a hard fiber cover over the sub then I have the stock floor mat and then the 40th floor mat. It seems to me that the path of the bass is so convoluted, most of the sound cannot get out. Next, I used to work for JBL and these little sub woofers cannot make much bass. I am guessing that the resonate frequency of these is over 1000 Hz. They are so stiffly suspended and they do not have much voice coil excursion. Has anybody tested the subs.
