Well I ran an 8" with 500 watts and asked people to guess what I had.
The guesses ranged from a 12" on 800 watts to two twelves on 2000 watts.
I took it to a custom car/car audio place nearby and had a guy with 15 plus years of car audio(he has a wall of sq and spl trophys) check it out and he was impressed how loud it was. The look on his face said far more than anuthing else.
That setup would only register in the upper 120s but was louder than most peoples setups with double to cone areA and power.
Your setup is def going to sou.d loud and refister a high score for sure, but my shit wont be any snooze fest ;) thats all im saying.
