[QUOTE="hispls, post: 8738102, member: 614752"] Sensor by the kick panel and doors/windows may be open. As opposed to dB drag style which is still the more common standard or reference which is meter at a particular place on the windshield and all doors and windows must be sealed. Up here our SPL classes do dB drag style and musical average classes require a door or window to be open. Some vehicles gain dramatically from door or window open, some gain little to nothing or even lose. You can build your install around gains depending where you meter and opening a door or window gains at least some in almost any vehicle. Pickup trucks are consistently the most dramatic gains for opening a door or window on the opposite side of the sensor. Go back and meter door/window open or closed with sensor both on the dash and on the floor and report the results. Hell, just sit in there with music going while you're in the driver's seat and have the passenger open his door or window and it should be noticeably more intense on your side. Lastly, the difference in cone area between 2 12" drivers is only 10% greater than 4 8" ones. Your outlaw score seems about right for what you have and I'd expect "legal" score would be 2-3dB down. You should not try to compare the numbers to those you'd get with the same power and cone are out of your VW bug regardless of how you meter. Pickup trucks are their own thing. [/QUOTE]
