Alright, I'm redoing this. Post your setup, with specific specs and I will make a leaderboard of the top ten systems. All measurements MUST be taken at windshield. I may request a receipt of your meter at any time.

1. loco-performance - 146.8 dB - Two 12" Alpine Type R, Unknown Box, One Alpine MRD-M1005
2. EmperorJJ1 - 146.7 dB - One Resonant Engineering MT
3. sick06cobalt - 146 dB - Two 12" Diamond D3's, Ported Box, Rocksford Fosgate T80002
4. HackAbuse - 140.8 dB - Four SoundStream PCW-12's Sealed w/ 1.5ft^3 per woofer. Two Soundstream PCA-1000D's
5. tiny - 140.5 dB - One 12" Kicker L7, 2.5ft^3 Ported @ 42hz, Kicker KX600.1W



Yes, I know this is a repost but I want this thread to be more organized.

Post up your systems, include all specs:

Subs, Amps, Boxes, Wiring, Car Prep, Measured dB, Where Measured, Pics.

If you post some ridiculous claim, expect to be called out.

I'll start.


Subs
Four Soundstream Audio Picasso 12's

Amps
Two Soundstream Audio PCA-1000D's

Boxes
Two Custom Designed, Custom Built Dual Chambered Sealed Boxes (6ft^3 total - 1.5ft^3 per sub)

Wiring
1/0 Gauge Wire - "Big 3"

Car Prep (dynomat)
---none---

Measured dB
140.8 @ windshield with TermLab (on 1000w RMS - now running 2000w RMS)

Pics

 

If SPL is your thing, that's cool, but I prefer SQ. By the way, I think that's the ugliest install I've ever seen!!! But, I guess that isn't a priority in the SPL world.

 

not too big on loudness but, my 2 12" L7s should get up there when needed.

 

Back in high school I had

2 - JL Audio 12W6 in a ported box I built myself (tried to tune to 30Hz)
1 - Rockford Fosgate Punch 200 (500 watts iirc)

In a 1992 Z24 with the back seat down and the speakers and port
all aimed at the front, I hit 140.6dB at the lower part of the windshield.
It was the only competition I went to and I made it to the finals!!!
I was in 1st place until the other guy hit 140.7 in the last 3 seconds to win
I got a stupid t-shirt and he got a 3ft tall trophy..... BOOOOO!!!


I'm pretty sure I'm gonna beat that by the end of the summer!
I ordered 2 Earthquake amps that put out 3000 watts RMS at 1ohm.
Plus 2 Kove Armageddon 15" subs. All I need now is a 4 channel amp
for the front and rear speakers and a BIG capacitor. I'll probably have to
upgrade the alternator and battery too.... Now I need to go to a local stereo shop
and see what kind of custom install they can do! I started about a year ago,
buying the parts one at a time.... I can't wait for this thing to finally be DONE!

 

I will be upgrading to an MA Audio HK802sx pretty soon. 4400w RMS ftw!

Depending on how my subs handle it, I may end up upgrading them.

 

subs
2 12 inch JL w3v2

amp
kenwood 7252

db
not sure... too cheap to have it read, but i would guess 120-130

 

Subs:
2 Diamond D3s 12"

Amp:
T80002 Rockford Frosgate Competiton Amp

Wiring:
Monster Cable 4 gage

Ported Custom Box- Thanks to Ultimate Electronics

No dynomat prep what so ever

Kenwood H/U

Monster Cable Capacitor

146 db

 

did anyone happen to see the blue balt at carlisle with this in his back seat. he was doing the DB comp and the windows looked like they were about to just pop right out. i dont think he is a member of the board...but it was seriously NUTS that the sub took up his entire back seat and trunk

 

who voted 150+ You gotta prove it

 

can i post specs on my old system? the new one isnt quite ready yet (may change drasticlly tomarrow thou

 

Sure... Why not.. did you do the 150+

 

nope (i havent voted st all yet)

ive only metered my old system once at a usaci comp and it hit 138.4 on the TL
Subs: 2 HE2 12s
Amp: 801s (800w rms)
Deck at the Time (sony stealth black face i think m800 was the model)
Wire: fosgate 4g amp kit
Box: Prefab dual chambered with 1cu per side

 

ill be getting my car metered soon.... Getting a sub box for a RE MT 15" for spl only running off my T30001bd amp

 

I would love to get my cars meetered, but have no clue where to go, the local shop doesn't have a meter or do any shows...Anyone in the chicago area have a meter and want to play? Or should I pick up a cheap one from Radioshack?

Is there a prefered song/ track/ sound to use for metering? I mean with 200watts to the tweeters I'm sure I could get way over 130, but your all talking sub frequencys...

 

subs: 2 12 inch kicker CVX
amp: mmats 1550 watts rms and 1 ohm 2100 max

 

cheap one from radioshack is worthless and any numbers you get from it are null and void with anyone who knows anything about car audio. Most metering is done using sine waves and on a term lab sensor (thats right its a sensor not a meter so you have to have pressure not volume) but sometimes the audiocontrol meter is used (problem is you must "tune" it so its possible for one guy in cali to hit 150db and one guy in new york to hit 140db with the exact same setup in the same car and in reality actually have the same amount of volume/pressure)

anyway i know theres someone with a TL in chicago if theres one in las cruces NM.... you just have to look harder. Check out the websites of some car audio comps and see if you can find any (USACI, DB drag, IASCA are the big ones)

 

Sub
Rockford Fosgate t115d4

Amp
Rockford fosgate power t10001bd

Box
Custom 3 cu foot box by audio express

Wiring
4 gauge

1.5 farad cap too

Car Prep (dynomat)
full trunk dynomat

Measured dB
Should be pushing 125db...


Im buying two t112d4's and another bd... hopefullt to get me to the high 140's maybe 150

 

any pics of your dynamat?

 

Thanks, I shall look for anything going on close by. Maybe I will get lucky.

 

I didnt take any pics of the mat but i did the whole trunk and the lid... makes a world of difference!!

 

I have one 12" Alpine Type-R sealed in a crappy box for now and then my amp is a Profile 1200. It works for now but does anyone have any suggestions for a good box for my sub. Like should i make a ported box or built a new sealed box?

 

i just checked usaci and they dont have anything coming up but db drag has quite a bit in the IL, MI, WI area (didnt check IASCI) heres a link to their schedule just put in USA for the country and you will be able to see all the events

anything over 150 db, will make you sick, we got lots of exageration going on here

last night @ orange julep they had a db stand, testing out audio, so i pulled in the line

i hit 137.8db @ 42 frequency and i did not have my favorite cd with me i am sure i could have top'ed out at 142, and not many people cant stay in my car for very long

running alpine head unit, 1x15"comp vr & 500 watt kicker/ 2 x10"comp vr & 600 watt

we had a guy hit 155db and he had a remote radio in the back of his truck, cause there is no way you could stand the pounding inside the cab

 

my brother gets into this stuff real serious... last year he took 7th place in the world finals in Lousivlle Kentucky for street max 3-4... his team is Team H&K Audio.. his name is jesse if you feel like looking it up on www.termpro.com

his system consists of a wall of 4 vfl competion american bass 3"voice coils subs linked @1 Ohm on 2 GD-6001 Audiopipe class d mono amps, 2 stinger 2150 batteries and ton of dyna mat

his best so far has only been 144.7 db but his box is not resdin inside yet nor is his port tune

 

cool... i dont do db drag much (actually never have) but that sounds pretty cool
