Thanks for responding akirby.
Yes in the walk around test mode it sends a tone through all 9 speakers.. This tone is louder coming out of each speaker than the normal volume level of the music I have playing. Thats why I was hoping the subwoofer had some sort of independent volume control or gain controller located on the sub/amp behind the hatch area.
I have actually turned up the bass in the bass/treble location of the sound controls of the touch screen interface but to my ears it just sounds like the other 8 speakers get deeper and it still doesnt give that "boom" I can feel when the speaker walk around test is occouring. In the test mode it actually vibrates the mirror. I dont get anything like that or even remotely close to full sound otherwise.
DSP modes, I have set it for "driver" but for almost a year I have had it set for "all seats" or whatever the term is.
I still havent figured out how to adjust the equalizer even though I can see it spectrum'd on the touch screen.
If there is something I am missing I would gladly tweak or adjust it.
I done need or want window rattling but honestly the wife and I feel its not full which it should be with a 8" sub in an enclosed cabin.
