if i want to turn it up, then the subs get turned off. if you dont believe cerwin vegas can reach 120db, then idk what to tell you. ive never pushed my sub to the point where i think it is going to blow up. my cerwin vega have been confirmed at 119.3db. i dont have a pic of it anymore, it was my moms friend who lent the SPL meter to me.
and also, id be willing to use a Pro audio sub. i was looking at an EV or JBL.
