My car ran 121 Db inside passenger cabin, and 127 in the trunk with the equipment listed in my signature. What is everyone else running db wise. Also that was cranked rite before the level of distortion.

 

what song/hz tone? also what mic and what size/type of box?

 

what are you running, i dont see your signature.

i havent got metered yet, but i expect around 138-140db. i'm running 2 Resonant Engineering 12' SE Subs with a Hifonics BX1500D

 

oh yea its also in a sealed enclosure. btw every +3 db is about twice as loud.

 

Negative.

Every 6db is 2x as loud, for most ppl that arnt used to sound pressure levels, every 10db will "sound" 2x as loud.

Every time you 2x the power, you get an increase (apprx) of 3db. Factor in cancelation, ect... and realistically is more like 2-2.5 but whos counting.


edit: Kikcaffine, your real score is 121 db, I dont know about you but I dont listen to music in my trunk

121 is average IMO. If this wasnt done at a db drag type comp, try getting it metered there. The new mics are kinda anoying and will list lower scores as well

 

Aww man, that sucks

 

wonder what my setup can hit...

 

Yours, not sure but I would guess atleast low 130's. This is the thing about SPL most ppl dont understand, they see a score of 138db and a score of 144db and think nothing of it. Fact is most ppl would **** themselves if they heard/felt 145db yet alone more then that. The sub & power alone doesnt make it a loud setup, its the install.
I havnt metered my setup yet, but to put in comparison I was in a truck that pulled a 141db score be4 they changed to the new mic's. My setup was definetly louder but a bit. So id say it was in the 144db or so range, but in the next comp the guy with the same setup pulled a 136-137db due to the newer mics, set conditions, ect...

Comparing to mine again, the difference is still there but the #'s are just lower so id still say mine is in the 139-140db area on the newer mics, but if you meter it with an older mic id say 144 or so (give or take )

Personally I dont worry much about SPL, my car isnt setup for SPL so I could squeeze more out if it, but its not necessary. So long as you like what you got thats all that matters, a 150db daily driver is retarded so I dont know why ppl try to aim for that score. Its kinda hard to breath at that level of output, yet alone drive

 

At the last Tweeter Slap Show (2004) I hit 142.1 db with my 2 - 12" MTX 9500 Subwoofers / Tuned down to 38hz with a MTX 1501d amp..

 

^^^ nice score. anything in the 130's is all i need. (and hopefully i do hit 130's with my setup).

 

Thanks man.. I agree anything over 130db is more then enough for everyday sounds..

 

i havent installed my system yet but what do you guys think itll hit?
-12" JBL GTI W12
-Audiobahn a2200hct
-Obcon 12" ported 18x36x16 enclosure
lets assume the install was done properly and tuned properly

 

Even 130's can be anoying after a little while, the last time I was on a road trip I had the sub pounding for a while, half way there (1hr later) I turned the sub down to abour 15-20% because the bass was just killing us, about 30min later I just turned the sub off, I couldnt stand anymore bass, its the last thing I wanted to hear at that point Loud bass is cool, but your body could only withstand it for so long.

Thats a common question on the audio forums, difficult to answer though. "Assumming" it was installed properly & tuning will obviously factor in as well, it should be loud enough

What loud enough for you is but you'll push over 130db thats 4 sure.

 

i haven't mic'd mine but i'd hope my l5's could break 130 legal (they're sealed)

 

i pulled a 158.6 on the old mics. all of this was from the trunk of my maxima. which consists of 2 15's several amps and other various goodies. this is my daily driver and it is okay to listen to daily, you just dont have to blare it all the time. every now and then it does get tiresome but you regain the satisfaction after watching people look in amazement.

 

yeah, bass can get tiring after awhile. even with my amp bass **** on the lowest setting, my sub still puts out decent amount. thinking about putting some sort of toggle switch on the remote turn on wire so i can turn off the amp if i'm not in the mood for bass.

 

when you say you hit 158 is taht with the seat down? i'm just curious. how much ofa diff does the rear seat make anyway?

 

A lot. The amount of air being moved is insane, if the air doenst go anywere its not going to reach max output. If I have my seat up its not that loud IMO, have to put the rear seats down and even crack the front windows a few inches to let it **** at max volume. Id say atleast a 10+ db difference in my car, I can tell the difference if I just drop the windows a bit. That air has got to move, 90% of the time ppl dont have a setup that will move this amount of air, but the other 10% do have to worry about this IMO.

 

Won't the sound pressure be higher with the windows up? I was bored today, so I played some IASCA tracks with windows up and down. with it up...i felt more pressure...but with it down...i can hear it being louder...not to mention spilling bass all over the place

 

142.9 with one 10

 

yeah the 158.6 was with the armrest in the back folded down, the metal plate that resides behind the armrest is removed also, and i have sort of a rectangular pass through hole cut into my rear deck. but yeah the bass notes get a little on the insane level. and the messed up part of it is that ive got used to it, so it doesnt seem that loud any more unless i go a long time without playing it.

 

It would make sense, but in some cases

gsumax Must have a damn nice install to do that.

So its not just me

 

Are you still running with the JL W6v2 10", because if you are that is a great score.. Especially if it was on the dash.. I am guessing that you are running a ported box? How low do you have it tuned?

 

well at the time of the testing i was running the JL, but my car was broken into a few months later....and yes it was in a ported box and both my back seats were down. as for how low it was tuned i dont reallly remember but i would say around 40hz would be a ballpark guess

 

+1. and it helps with rattling if i have my rear passenger seat down. however i just put it back up because im tired of the bass. i do think it would help my score significantly when the rear seats are down. i wish i had a mic to play around with...

 

rattling from the inside or the outside....the car rattles more from the outside if the seats up but the inside of the car rattles MUCH more with the seat down (i guess from the increased spl right)

 

well it rattles less with the passenger seat down and it rattles less on the inside...except i get a rattle from the black plastic covering the blue paint behind the seats because i did not put them on correctly after i put foam under the rear deck.

 

i just have rattling period...mostly the trunk and the red plastic that says "maxima" on my 3rd gen . time to get some sound deadener

 

I think im somewhere in the low 130's with my setup.

I prefer to crank it LOUD though with rock and just listen to the SQ of the system, nothing like REALLY loud and no distortion and still sounding as clean as it is when half cranked.

 

146 in my cadillac, 132 in my lincoln, 135 in my stealth, the max doesnt have a system


Those are measured at the dash with a sine wave CD , and is most likely a little louder than the cars could ever be with anything resembling music.

 

You guys produce some nice numbers...I kinda wonder how the SQL would sound but for SPL those are nice digits.
Personally, I am running a Xtant A 12 with an Eclipse Amp(300w) and hit 128 at SLAP...but my setup is for SQL not SPL.
I definitley agree with many of the people on here who mention that the install/tunning is very important. I can't stress that enough. You can have all the power in the world and sound like crap without proper tuning and install.
Also it's important to keep in mind that power doesn't necessarily translate into loudness...it's really about quality. I know if I added power to my setup it probably would not get any louder than it is right now but the bass notes would definitley hit deeper and tighter.
Those are just my thoughts.

 

is it easy to be well into the 140s without sound deadening on 5th gens? i have money for equipment but geez i'd have to postpone and postpone for deadening, pos...

 

Just hit 138db with one Sony 12" Xplod and Sony 2100 amp. The other 2100 is running a Rockford comp set. This is all in a Scion. Here's the pics.

 

ohhhh...what software is that?
