SPL is decieving. Most people run their subs 10 to 20 db above their front stage and don't even know it. So yeah...120db is possible on a "C" weighted meter with music...but's probably the bass doing it.
For the record, I have RTA graphs of just my front stage running over 115 db from 35hz up to 15khz (HF roll off). Does that mean I have a 115 db front stage? In my oppinion NO.
I would say a 102 to 105 db "C" weighted average is pretty darn loud. My goal is to be able to hit this SPL and still have headroom for the 10 to 20 db of natural dynamic peaks in most music.
So for now, my 105 db goal stands...although the SQL term could easily be applied to this if it was better understood.

Do you guys realize just how loud 100dB's is?
For reference, most movie theaters are calibrated to 85dB at the center seat (with 105dB peaks).
It wasn't me who said SQL is not applicable in car audio...in fact I use the term myself. Fatty is right, it comes down to what your definition of loud is.
