you guys are hilarious. 140 db with almost any subwoofer aint ****. i have a single 15 in my truck that does a 141.47db. when i had my 4 12's i was doing a 146.98. people that are not competitors have no idea how easy 140 is. 150 is a completely different story though. go to a stereo competition then tell me 140 is not possible with 1 subwoofers. alan dante the loudest man on earth hits a 181+ with a single 18. a guy in cali is doing a 150+ with a type r 10 and 4,000 rms.
