So I'm about to help a buddy with his impala install but his back seats don't fold down. so I was pondering the idea of figuring out the remaining volume of the trunk after everything is installed and when we rebuild the rear deck actually tuning the vent so it's basically a 6th order.... Anyone done this with good results or should we just cut out as much of the rear deck as possible and call it a day. Running two MT/PSI 12''s on a skar4500.
To find sealed resonance
resolve Vas/28.32 =
result of that divided by Vb( box volume)
result of that +1
square root that result
result of that multiplied by FS
