Can you turn it up, My left testical didn't explode yet!

Sat in the loudest car i have ever heard last night.

The guy was running 4 MMatts 15" subs . He said his 2 MMatts amps were 1400 watts apiece, not knowing mmatts i can't verify this. He said it hit 157db at the windshield. Like the psychopath I am I sat in the back seat of the Blazer.

My friends Bronco hits 140+, I could not imagine what 157 would sound like from a Car.

 

[1sty]

Its not really sound so much as your inner ear vibrating like a bastard.

 

[frady2001]

that sounds right. being a bronco and pushing 700 each to mmats(very good speakers) should be frieking awsome. also 157 is a world louder than 140+.

 

[1sty]

techniacly 4 times as loud i believe.

 

[NetGuy]

My old CRX hit 147.5 with 6 12" on 500W (total). Yeah, that was bad enough, I can't imagine what 157 would be like. I used to be able to rattle parts of my friends car (driving in front of me) driving down the road at 80km/h

<nelson> Ha Ha! </nelson>

Call me stupid, ignorant, whatever, but being in the medical field for the US Army, I have seen many different soldiers for numerous ear related problems.
Most recently a soldier of mine was injured during a live fire exercise where an AT-4(Anti-Tank Missle, fired from the shoulder), was launched about 5 feet from his ear. He now wears a hearing aid in one ear, and is completely deaf in the other. They say that it is equivilent to around 160db + or - 10db, depending on distance from the object. And that was after a 1.2 second blast.
So my question is, why would you subject yourself to that kind of sound to begin with, especially in an enclosed car? Do you want to be deaf? I dunno, just my $.02, sorry.

 

[Sir Nuke]

why does anyone do ANYTHING that is dangerous....because they can...

PERSONALLY.....i think its moronic to jump out of a PERFECTLY good airplane.....even with a parachute....that is unless the plane is crashing anyway. but some people think its FUN. SOOOOO there ya go.

(stash)

 

[1sty]

He didn't put it up that loud when I was in there. It was easily 140 I'd guess 145. At a competition he hit 157.

 

[rmedoc]

Very true Nuke. I wouldn't either. I never did understand why they call it jumping from a plane anyways. You don't even jump, its more like falling if you ask me!

The loudest car we ever built at my shop could hold a steady 158 db, and once it peaked over 160. This was over 4 years ago, without any "Wells Fargo Truck" windshield or other unusual body bracing. This was in a full-size Suburban, with 12 of the old-style JBL GTI 12 inch subs in 6 slot-loaded enclosures. Each sub was powered by a Rockford Power 500, bridged mono. Three more Power 500's brought up the rest of the sound, with various horns and mid-tweet combos. During regular listening at a usable volume, this actually sounded very good.
I was actually sitting in the front seat when we hit the peak. The RTA we were using to tune it only went to 160, and I was wearing hearing protection to the tune of the roll-up inserts covered by headphones. We held a constant 158 for about two minutes, and my partner signaled to go ahead just one more notch. We watched the numbers hit 159.2, then .6, then "OVER" and we called it good. Only when I shut it off and opened the door did I realize how much trouble I was having BREATHING!

If anyone's interested as to how we juiced that many amps, this rig had a custom alternator bracket holding 2 dual-250 amp alternators and custom rectifier setup, charging 8 Optima's and 15 Farads worth of caps (remember, this was still back when we only had the can-style capacitors available).

wow

thats all i can say...

wow....

and where can i pick up a decible meter or whatever something like that is called... and whats the price for a cheapy one?

also... a friend of mine's got buddies that goes to the db drags and blows out his windows... that seems like an expensive habbit to me... but whatever floats your boat...

I'm big on the car audio.. i suppose its partially for the same reason i'm big on all the other "extreme" or "wild" mods, like crazy body kits (i do still have taste though... example: i HATED the onderground kit ) and things like that.. the attention... I wanna be able to be heard comin down the street.. i want people in restaurants to be like WTF was that when i pass by rattling the glass... at work im on the second floor of a corporate building and i hear people goin by sometimes..

the thing with the protege's is they have AWESOME sound insulation, which is good for the normal person, but bad for me.. i wanna be able to hear my engine and hear my exhaust and i want people outside to be able to hear my system... i've noticed it is a HELL OF ALOT louder with the doors open then with just the windows.. i know thats obvious, but it seems like most other cars (honduhs/acuras/whatever else) aren't so soundproofed...

anyone here ever been to the db drags and blown out any windows?? or seen it in action...

also.. (sorry.. long post) how do the decible meter thingies work??
they just have a small mic sensor on them and you hold them up in the center of the car or wherever you want to measure?? or do they tap into the wiring somewhere??

oh yah... and HOLY ****** s***!!! 15 farads woth of capacitors?? god damn! me thinks i need another one too... all my accessories still dim when those 12s hit...

Alumipro make a 5, 15 and 50 farad cap

 

[frady2001]

about three or four years ago I helped a buddy of mine build a competition car. now this was purely competition(i.e. wells fargo windshield, 8 13 volt truck batterys in the back, completely stripped of all vibrating or non solid materials, completly walled of and sealed with liquid nail). we brought it to daytona one year and with 6 12s and a small nuclear reactor in the back(jk) hit 172. they told me that if you were to be in the car when they burped it that your heart would explode and you would(obviusly) die instantly. no matter how much alchohol we gave a buddy of ours he wouldnt get in and test it so whether or not its true i dont know but the iasca judge seemed like he knew what he was talking about.

 

[1sty]

He'd start puking around 165.

Alumipro make a 5, 15 and 50 farad cap

Yeah, but like I said, this was at least 4 years ago, before those were available. We actually had a row of round caps linked together with a bus bar (another custom build, we had one bad-ass machine shop)

I never really had a whole lot of luck with those Alumipro style ones, anyway. The discharge solenoids were always going bad and causing battery drain (although mostly on the Pheonix Gold version, but I still had three or four Alumipro's do it). That and idiot salesguys were always selling them to cure dimming headlights. They never understood that caps are intended to help keep constant voltage to the amps during quick bursts of power. The fact that sometimes it helps keep the headlights from dimming is a positive side effect, not the intended result.

i had the displeasure of sitting in a tahoe with 8 JL W6 12in subs and four PPI amps. dude had six batteries and two alternators. also a super charger and about 20k worth of other s***. i can't remember but i think he was up around 160db. won everything he went to. when the bass hit the first time, it blew my hat off. no s***.

 

[Protege01MP3]

HAHA lol good s***!!

 

[brokemp3]

i had 2 spl 160 when they came out. and a pg ms270 amp. it was in the back of a 88 hyndai excell it hit 158.3 once and it took out the side windows, the ones you can pop out like the ones in vans. just the subs cost more then my whole car did at the time. but it was loud it made little rocks bounce of the ground. around the car

 

[LazerBlueP5]

Hmmm I'm getting an Alumapro CAP 5 installed soon hope what your saying, "sttl013", wont apply to mine. *crossing fingers*

Can you explain more of this "discharge solenoid" problem"?
