OH yeah....Piecesparts..not to undershadow your install...but if someone told you that your truck measured 300db, they need to get a new meter or get thiers calibrated. 300db would damn near implode your head haha! And Bazooka's arent gonna hit that hard unfortunately.
The IASCA record for 2005 is as follows in the unlimited class
Scott Owens
Tempe, AZ. USA
2002 Ford F-250
*180.3 dB
Anything over 140 is damn hard to acheive and VERY VERY VERY expensive. My old truck hit 143.3 Db and then immediately Blew both subs and the amp lol. Tuned it down after that.
That alone is enough to make you feel woosey after an extended time, not to mention ear damage lol.
