You most definitely need to state the vehicle, measurements of area to be used, what amp, sub model numbers, and your ultimate goal of this subwoofer enclosure.
It's been years since I have been really active in car audio forums. I posted a ton about 10 years ago here on caraudio.com, termpro.com, sounddomain.com, caraudioforum.com, and a whole bunch more that I no longer remember. You may remember me. If not, you're probably just young haha. Because of the many years since I've done any selling / buying, the only person I can remember for my references is Team PSI (David Moore).
