Anyone know?
Got a bet going with a friend i need to get this as loud as possible without changing subs and amp, not worried about sound quality as this is just about spl with this car. Stock bodied, no bracing, no deadening.

Mid to high 40's Try a sweep from 43-48. Just a guess but I bet I'm in the ball park.
