Been here awhile...
I have built, designed, installed, and tuned many car stereo systems. I usually stay away from specifically marketed "car audio" speakers. I opt for drivers of higher quality usually Vifa, Seas, Eminence, and Dayton and source my products from www.partsexpress.com! What you would pay for a JL Audio W7 I can get a BETTER DVC sub for 120.00. It is my humble opinion that the car audio market is about bling not performance. I prefer sound quality!
Because of cabin gain (the volume of air inside of the car resonates at a certain frequency.) Dialing in a subwoofer can be very tricky so I use a CD from Bass Mechanics http://www.cduniverse.com/productinfo.asp?pid=6770389 they offer individual hz wave and sweep waves so you can tune to your ear and the car; even a sweep from 40hz - 0hz
I am posting this B/C there has been allot of debate/discourse about the stock subwoofer in the TEK package (17 speaker 7.1 surround) being un desirable.
I did some testing today with the cd and the TINY 8" subwoofer will faithfully reproduce down to 24hz I think the F-3 is right about 21hz (F-3 is the point where the bass drops 3DB bellow reference point.) There is some cabin gain around 51hz but still the bass is powerful and the Q seems to be about .700 so it's quite controlled.
The more I test this system the more I am impressed with it. BTW I also make audiophile home speakers for fun......
