WTF??? yes I heard right........
I was at the audio shop the other day and they got the Kicker soloX subs, almost $1,000 and some kid walks in and orders 2 of them. He asked if he would hit 200 SPL 
and the shop owner said he would get very close. I think he needs a 15 cubic foot box for them and they are the 18" soloX's. Why would someone need this? He said he also had top of the line Audiobahn amps and JL audio where junk? WTF? is he an idiot?

i don't wnat to use the word never but I think it's legit to say that no car will ever hit 200db
well i didn't SAY never there, but you get the idea

Rep Power: 0 when the kid asked, I was stunned and knew he knows nothing about car audio. The shop owner just wants a sale and said he would have to add batterys and altenators to come close to 200 db. I understand what your saying, it has never been done so therefor it's next to immpossible.

Rep Power: 786 Not just becuase it's never been done, but just based on what people are hitting now and some assenine physics that I don't understand makes me say it will never happen.
Why would somebody want to know if he could hit 200db? Becuase he's an idiot

And in any case, I believe rockets launching don't even hit 200dB.
So I'd be quite willing to say it is impossible to achieve 200dB using stereo equipment inside of a car.

Rep Power: 0 This was from a website about audio competitions...
'Racers' pump up the volume
In this automotive competition, it's the power in the speakers, not under the hood, that counts.

SARASOTA -- It is not a quiet Sunday afternoon. It's loud, very loud, just the way Andrew Harper of Miami likes it.
"I had the sixth-loudest street vehicle in the world" last year, Harper said, boasting about his accomplishments in dB Drag Racing. It's a competition in which the dB stands for decibels, no drag racing occurs and a car's sound system is the star, not its engine.
DB Drag Racing is a relatively new phenomenon, a hobby for the boomingest auto sound systems and the people who love them. It has local and regional competitions that lead to national events (www.termpro.com/dbdrag/).
To get as much sound as possible, contestants install 1000-watt power amplifiers and pairs of 12-inch bass speakers, called woofers. Some even install customized door or roof panels or fill their doors with concrete to keep the sound pressure level, or SPL, up inside.
"Well, I can tell you I probably have $4,000 in woofers and amplifiers" in the car, Harper said.
On this particular Sunday, the competition attracts a crowd mostly of 20-somethings to a strip mall on old Route 301 to see how their audio levels stack up against others.
The loosely structured auto show included prizes for wild, import, domestic, lights, interiors and, of course, best in show. Some young men fussed over their fancy cars and lined up their trophies from past contests as other contestants rolled in.
Sedans leaped and lurched about, powered by the hydraulics of low riders, while SUVs arrived seeming larger and more menacing than usual. No matter the type of vehicle, they all had one thing in common -- serious sound.
The featured event was the officially sanctioned dB Drag Racing competition. Decibel is a measurement of the loudness of a sound, which is the point of the competition.
Cars were driven into the garage of Autotronics, a custom car shop, to get their sound pressure level assessed. The crowd gathered around the computer monitor that displayed the recorded decibel levels, evidence that this was indeed the main event.
Two at a time the cars had a microphone, connected to a computer, placed in the passenger compartment. The contestants either put in ear plugs or got out of the cars and turned the volume up, way up.
The computer recorded the highest decibel reading the sound systems put out. Some contestants even leaned against their car doors in an effort to keep the sound pressure from escaping. While not ear-shattering, standing a few feet from a car sounded like an approaching Florida thunderstorm.
Instead of playing techno or hip-hop selections, contestants are required to play the same, single low tone, like protracted thunder, because it makes the testing more accurate. Quite a few cars recorded more than 150 decibels.
How loud is 150 decibels? A 747 taking off on a runway 300 feet from you is about 120 decibels, average street noise is 85 decibels and a library is 35 decibels. And get this: The winner of last year's overall competition in Nashville, Tenn., reached 177.7 decibels.

Rep Power: 310 That guy is a complete moron! Not only is top of the line audiobahn a joke in itself, were does this loser come off telling that kid he'll get close to 200 with just 2 of those subs? Last I checked it took some guy in a caravan like 70-something amps to hit 179 for the world record.

who remembers the three phases of matter and the volume/pressure laws. remember, that you can change a gas, into a liquid, with sufficient pressure added. this applies to everything.
so
i forget if its 186 or 194, but thats the point you exceed the pressure that air can withstand.
the air would literally turn to liquid.
it wouldnt be possible.
theeeeeeeeen
thats why in the rulebook for dbdrag, it says that the car cant be filled with any gas or anything

It discusses the loudest possible SPL that is possible

Rep Power: 0 Loudest Animal Sound - From Guiness
The loudest animal sounds are the low-frequency pulses made by blue whales (Balaenoptera musculus) and fin whales (B. physalus) when communicating with each other. They have been measured at up to 188 decibels.
Thought this was neat.....
It also said that over 192 db a lethal over pressure shockwave could be produced....Meaning it was loud but you might die from it.......
