151.9 in a trunk is very hard to do. What mic was it measured on? Term lab or Linear X? Either way its very impressive. I know Team Stereo One (Before they got banned) used Mojos for numerous world records. And man can those things take some juice. They had a quad 1ohm 15 with 2500D amps to each coil and it would hold. Bad thing is the Mojos get sloppy the louder they get. But a 150db daily driver is awesome IMO.
