FEATHER RUFFLER
That's a great gain for window open. I don't think I've ever gained more than 1dB in either of my Jeeps with any subs for opening door/window. Not like I have tested a lot though since we don't meter that way around here. Might see what's up with that next time I have the seats out though.
There's a VERY loud Tahoe up this way with c-pillar wall. He doesn't go on the meter but I know he knows how it does. Feels very intense, carries like crazy with the doors open. Some of the big SUVs can do well enough, the big benefit is they have enough cargo area for proper size box, batteries, and amps. I feel that's the biggest thing that held down numbers on mine was just skimping on port area and box volume.
The 158.6 was crossfire 8k
The 156.8 was vital power sealed
The crossfire sealed did 157.xx
