ok, i'll be the first to actually help. lol.

What car is this going in to? Location of subs? There's many variables that account for how many DBs a system will hit...

but on top of all that, no one, and i mean NO ONE will now how many dbs you'll hit, only approximate GUESSES.

dude you obviously don't know ****.

Just find the sensitivity of your subs and multiply by 4. Unless they're single voice coil, then you will want to multiply by 2 instead of 4. That will tell you almost exactly the kind of numbers you will be looking at.

You all are ****in stupid. The record is like 180 something with 1 sub. Size doesnt matter, he has 4, he should easily be around 250 dbz. Depending on vehicle you might get a little lower but do a sealed box so the waves will come straight out off the sub instead of being redirected. That will add Dbz
