monkeyleg Posted June 20, 2019 Report Share Posted June 20, 2019 My matching sub unwound. So while I wait for upgraded recones, might as well play around with my working one with no regard for blowing it. 2014 CrewCab F-150. Prs80 100ah lithium 2 banda 7ks 1 ohm versions 1 10" NSv4 D2 with SPL surround. Box will be on the back floor. Cabin is so big I have unloading issues unless port fires into door. Loudest so far in this truck is a pair of 10" Zv5s in a 1:3 4th, on a banda 7k each, at 2 ohm, 146.xxdb at 45hz. Never played around with burp boxes. Was thinking a 1 cube sealed cube to find resonant frequency. Then build a 1.5 cube box that I can shrink, and an aero port to shrink as well. Don't know diameter yet. What am I looking for port wise? 12-16sq.in. per cube for musical boxes...is there a rule for spl? Tune 45hz and up? Google it Link to comment Share on other sites More sharing options...
