I am just curious as to what would be considered a high spl number on the metwe for a sub woofer set up?

145 is around where it starts to tickle your ears or u start to feel slight pressure in them

150 is around where u will have feelings of chest pressure and heavy pressure in ur ears

155 is around where u are at a point that will be impossible to swallow and will not be able to take the pressure in ur ears for long durations

160 is around where if u do not get out of the vehicle soon, u will more than likely experience immediate hearing damage longterm without knowing it right away.

Thanks man that was great!

Hmm well 180 dbs is pretty high since it is just under the world record if Im not mistaken. Id owe you a handshake if you could pull it off

this isnt exact science, frequency that produces said pressure will have a great effect on what was mentioned above.

Typically, the lower the frequency, the sooner it may happen.

155 is hurt your ass loud especially at low frequencies.
