bkolfo4 Posted June 3, 2009 Report Posted June 3, 2009 Why so much port area? You only need 80-100 inches. Gross volume could be much smaller.

EricM9104 Posted June 3, 2009 Author Report Posted June 3, 2009 Changed it up to 8.4^3' gross, 7.17^3' net after sub/port displacement. Tuning at 35Hz with 99^2" port area. 2015 Honda Civic LX 4dr | 110k miles | Stock 1996 GMC Yukon SLT 4dr 4wd | 260k miles | JVC Head-unit
bkolfo4 Posted June 3, 2009 Report Posted June 3, 2009 Sounds good. Why the jump from 30 Hz to 35 Hz on the tuning? What is your goal for this setup? Just curious since your current Q box is tuned to 29 Hz. You may want to tune around 32 Hz.

EricM9104 Posted June 3, 2009 Author Report Posted June 3, 2009 Best tuning I could figure at the time without having to go through and mess with numbers... Again... This time, same port, extended the box 2" though. Now got, 7.08^3' after sub/port displacement, tuned at 29.96Hz, same 99^2" of port. 2015 Honda Civic LX 4dr | 110k miles | Stock 1996 GMC Yukon SLT 4dr 4wd | 260k miles | JVC Head-unit
