I currently have a set of alpine 4x6 in the front a set of alpine 6x9 both type s and in the trunk I have two alpine type r two ohm. And powering the front and rear I have 2 audiobahn a2002t amps and the subs a2200hct amp and the gain is at a 1/4 any help or suggestions oh the subs are in a vented box 2 cubic feet total

G1... iPhone? If so, 102 isn't even CLOSE to what you are actually making.
Use a real dB meter, then come back and talk to us.

Ok but any suggestions on how I can raise it. I was thingin of playing wit the eualizations and raising the gin a lil bit but when I did that the bass was louder than my inteior speakers and all you hear is the interior speakers and this loud deep bass.

I can't make heads or tails of what you are asking... PLEASE use some punctuation; we can forgive spelling errors (even though we SHOULDN'T, but at the same time we need to seriously thank Ahhnald for leaving no child behind), but geez, man, the run-on sentences that you insist on using are NOT conveying a clear image of what you want.

Maybe what he means is that you should put the stereo down, and go back to school. If you are still IN school, WAKE UP! Put the weed down, and pay attention. If you speak in person like you type on an internet forum, all I can see in my mind is Jeff Spicoli.

ok basically i wanted to know is, can i up my db in my current stereo setup or should i upgrade some parts of it to accomplish that. i was thinking of turning up the gain but when i had the gain up the bass was much louder and it drowned out my mids and highs. so should i upgrade my interior speakers and turn up the gain or upgrade all my speakers. or a different brand in amps. my main goal is to get the most of what i have now and upgrade little as possbile

Thank you... Now, was that so painful?
Anyway. There are two ways to make more sound, which is what you are after...
1: More power.
2: More speakers.
If you have no space for #2, then you MUST provide the current speakers with more power. A doubling of power will increase their output by 3dB, a barely noticeable difference, if at all. If your current speakers cannot handle more power, then you must replace them with something either a: more efficient, or b: higher power handling. I have never heard of regular, everyday speakers that are efficient enough or have high enough power handling to reach those SPLs. You are now left with esoterica. Esoteric means $$. Lots and lots of $$.
Now... What is your budget? It's not cheap to make noise, and by the time you reach your desired 140dB line, you WILL have spent thousands of dollars, in either speakers, amplifiers and/or installation. Does it sound as if I am trying to talk you out of doing this? Well, I am. It's folly, and by the time you reach 19, you won't be able to hear a thing! As little as 15 minutes a day of 115dB WILL cause hearing loss.
Here are the OSHA mandated noise limits for a workplace environment:
Exposure Time Exposure Level (measured in dB SPL)
8 Hours 90 dB SPL
6 Hours 92 dB SPL
4 Hours 95 dB SPL
3 Hours 97 dB SPL
2 Hours 100 dB SPL
1.5 Hours 102 dB SPL
1 Hours 105 dB SPL
.5 Hours 110 dB SPL
.25 Hours 115 dB SPL
You can see that even at your already acheiveable SPL of 102dB, you are already causing significant damage to your earing by listening more than 90 minutes a day, which I am sure you are doing. I might also mention that the 102 you are already hitting is an AVERAGE, with peaks being significantly higher than that, adding to the speed at which you ARE damaging your hearing.

Another way to make any radio hit 140db is to load it into a cannon and fire it against a wall. ------------- Support the12volt.com

Most radios can do over 120dB's . . . only once. Run power supply to radio from wall socket thru a switch. Throw switch. Voila 120dB!. P.S. Wear ear and eye protection and pretest microphone because you'll only have one chance to sample this tone burst. Let us know how it turns out. ------------- Prepare your future.

When he initially made this thread, there was a typo in the subject line. It read I want my radio to hit 1140Db. I was thinking he meant to say 140, Then after reading it, I was not sure if he meant 140 or 114. At that point I could only assume that he meant 1140. By the time I posted, "That is going to take a whole lot of Diesel and Urea" the mods had corrected the subject. So in order to not look like an Idiot, I deleted my post.

HAHA! The cannon might get 140 but he radio hitting the wall maybe 20db...mostly by the guy next to the cannon as the metal shards come flying at his face!

thanks for the replies. im aware of the db chart i googled it and researched it before i posted this thread. yeah the reason why i want to hit 140 db is i never heard a radio that loud and i want to hear it from a distance not up front i like my gift of hearing. as for installation i do my own work and im 25 so if i deaf already i wouldnt want to hit 140db. so im going to change my speakers maybe go with a bigger amp throw 2 type x's or fi car audio subs in there i heard those are great. and when i tested the radio at 102 i did have hearing protection . the subs i have now you can feel the air moving from outside the truunk. my second question i was getting 102 in the trunk alone and inside the car i was getting 100db why is that.

yeah sounds good what kind of wiring did you use and how did you wire the subs. where they wired at one ohm. also what kind of amp you had

...the amp was a ppi, i think.. but I don't remember the model #. :/
The enclosure was custom built for a cow painted minivan (Chrysler/Plymouth voyager?)
And wired in parallel / parallel...measured at .89ohms or something like that...almost an ohm.
The enclosure was about 3.5 cubic inches of air per chamber. Ported ,tuned to 40hz.
We tried a HIFONICS Brutus but it gave out around 135db.
Then i think the ppi was installed...i gotta look for the pics in the old cabinet.

There is to many factors involved for us to just tell you how to get 140 decibels. Your cabin frequency, air space, power, electrical is all going to come into play. From the sounds of your reply's you have a lot of reasearch to do start reading man. Im working on my new setup right now 2 sundown saz 3000d and 2 12" dc level 5's

140db shouldn't be too hard.
In my explorer I had a single 15 with 800 watts and was hitting over 140db.

$5000? you got totally ripped off as far as performance goes. what exactly made your setup cost $5000?
you dont need to spend tons of money to get good loud bass. you just need to have the knowledge to spend the money in the right places that make the most difference to performance. a do-it-yourself install will also drop the price dramatically and it will be way more satisfying than just dropping your car off at a shop. -------------

He also didn't ask about his BASS hitting 140dB... IIANM, he wants his ENTIRE SYSTEM to be that loud.
Oh, and you DID get jammed. Did they supply any kind of kiss with that $5K?

your right, it aint easy. you cant just go out and buy random equipment and expect to hit 150. but if you know a little bit about what you are doing, its not that hard to do. anyone can hit 150 in a daily driver if they have the space for the equipment, the knowledge of how to use the equipment, and some cash to buy the equipment. -------------

all these db posts. With the equipment you have, you can achieve 140DB. Really it would be achivible with maybe a stronger amp and a better box.
Find a shop that has a Term-Lab meter, only realy meter to go by, and start from there.
Your I phone will tell you nothing.

Did you mean to say he can't achieve 140 with his equipment?
Posted By: vibrationcustum
Date Posted: May 08, 2009 at 11:26 PM
Maybe he can change the db by the way the box is setup in the car. If the subs are face back change it to facing towards the front or facing up. I seen that alot of times in cars. Just to let you know 150 is very hard to hit but can been done with spending $2000 if you know what to get and have a lot of know how and the right car to put it in.

i have the subs facing the rear of my car. the reason being i made a custom setup and maybe rotating the box might not look ok. but i know you are going to get on my case about this but when i used my phone to check the db i got the same numbers. so idk if thats because of the phone not being precise or the sound level is the same
