My experience and some details:

1. I built one first for the driver side to ensure that I did not lose any leg room; thus the dimensions. Satisfied, I built the second one. Note that my brother who is 5'10 required more legroom and he wanted the box out when he test drove the car; what I am saying here is these boxes fit my driving position --- it may not fit yours. So build one first.
2. The speaker is off-centered and sits lower to the floor to allow the woofer to expand without the seat interfering.
3. The TangBand subs appeared to be only one the fit my needs.
4. I used a speaker-box-calculator to determine the volume required.
5. The bass coming from these boxes are more than enough for me. It may not for you --- "music (or bass) is to ear of the beholder!!!!
6. I do have Dynaudio components so I am not sure if the Dynos produce some bass that complement the subs.

Cheers!
