141.6 is not bad for 2 12's. With a little assistance (holding panels/opening doors-windows), you may gain a dB or so.Vehicle: 1993 Grand CherokeeElectrical System: stock

Thanx! yeah so with the jeep totally closed up i think the score is preaty good, specially with this new mic141.6 is not bad for 2 12's. With a little assistance (holding panels/opening doors-windows), you may gain a dB or so.
I've never seen SPL measured that way, but I'm somewhat of a newb. Also, it depends on the meter/sensor they used. AudioControl mics tend to be 4-5 dB higher than the TermLab sensor.I had my 4 Runner tested in Sav. Georgia. They told me it was running 149.7 at 50hz. I have a Virtual technology box (Transmission Line box) Loaded with 12" Rockford Fosgate HX2 there are two of them being powered by a MMATS 200HC. The 149.7 does not seem right with what you all are posting, seems to high. This was in the driver's seat the headrest was removed. Is there different kinds of meters out there?
