This was talked about a lil bit before, but can I get some tips and tricks on how to burp from some of the competitors out there?

...FYI, my box is currently sealed (2 IDMax in 1.4 cubes each). I wish I still had this in my car...

Pause your CD player, find the hz you want (use ONLY tones such as 50hz etc, don't use sweeps or music or anythign else, just flat tones). While still paused, crank the volume up to whatever level you like, signal to the judge that you are ready and when he says go, unpause for 1-1.5 seconds. Pause again. Now what you do after this depends on your personal preference, but what I do is halfway through the round, I do another 1-1.5 sec burp 2 hz higher than what I started at, then at the end of the round, another at 2hz lower than what I started at. You may prefer to only deviate 1hz either way, or just do 1 burp and leave it, it's up to you.

With sealed you should probably do a sweep around your optimum freq for your box.

All i have is this damn Bass Mekanic CD that has stereo test tones that sweep from 40-40.5, 41-41.5 hrtz etc...any recommendations on CDs that i can buy from somewhere like Bestbuy.

If you talk to ludlam he might be nice and input your box dimensions and make you a sweep tuned for your box.

 
Rep Power: 346

LOL, is he ever nice j/k!

 
Rep Power: 786

The problem with a sweep is that it will kill your battery quickly and not give you a chance to gain dB if you do not hit your peak right off the bat

In other words your battery will be too weak after the first couple seconds to give you any gain

 
Rep Power: 328

Thats what bigger batteries are for. I really dont see that killing a battery though, considering you can rev to 2,000 during competition.

 
Rep Power: 346

This is the type of stuff I need to know

depends on how much power youre running really. neither of you two are running enough power to really kill a battery all that quickly.
you have to remember, car batteries are able to put out a huge amount of amperage for a short period of time,

 
Rep Power: 786

But even as they put out a huge amount of amperage for a short period of time, they are losing that critical wee bit of charge that could make the difference between a win and a loss.

I mean, I have seen people gain during a round using sweeps, but not as many who I have seen stick at their original number or number they posted during the first couple of seconds.

If anything, get a really quick sweep that covers all your tones in like 2 seconds, that way if the car is running, you can give the battery a chance to gain back that small bit of charge that you lost

You can run your car in every competition class that I know of, except for dB Drag Racing Street A which is their most entry level class.

If you want to upgrade to Super Street where you can also add a second battery, then you can run your car (and have a wall )

Fonto, each competition "company" or whatever you want to call it has different rules.

Read up on rules at these sites:

http://www.soundoff.org/
http://www.iasca.com/
http://www.slapshow.com/

Each one has different ways to categorize your car, and different rules.
I like SLAP because you get two runs through the lanes for your $20.

I'm assuming you just want to meter your system, and arent really looking to get into this competitively....

 
Rep Power: 346

No, i am actually going to a competition on Saturday...even though my car and box is so not set up for SPL right now.

 
Rep Power: 328

Well yes, they are all competitions, but are you going to start competing, or do you just want to see how loud it is?

 
Rep Power: 346

Well, my car is not really a great SPL car (it has been better/louder previously) or a great SQ car. My plan is to see what I do better in and focus on one.

...ideally, I wish there was some type of SQL circuit...my system would be best suited for SQL.

...also, i don't want to be laughed out of the lanes with my JBL amp

...but who knows, maybe the JBL will become a classic in the future with it no longer being produced ...hey, how many amps can put out the same amount of power at 1 and 2 ohms ...even though more and more amps are able to do this.

 
Rep Power: 328

Dude, I have seen guys compete with "crunch" series amps, and speakers from radioshak and win...it's not about brands. Install really is a HUGE part.

 
Rep Power: 346

LOL, then my fate is sealed...I'm gonna do bad

Rep Power: 329

yup i saw a guy compete with 3 boss amps last saturday. in a 300z. 3 10's (i forget what make, i wrote him off because of his amps). he hit like 144 and was in first place when i left.

 
Rep Power: 786

Do you recall his name?

Amen brother!

Fonto, if you like, hit me up on AIM or MSN and you can ask whatever questions you want, I'll make sure you win that ****

Question (since I've yet to attend a competition, but I'm getting realllly interested):

When they measure SPL, are they using C-weighting? I know most noise laws are A-weight....

Thanks!

LOL, my wife won't let me have either

dont forget four areoports...lol

standard CRX box calls for them.

What's a burp?

 
Rep Power: 346

You play a short burst of Bass in order to reach a high SPL.

 
Rep Power: 786

Slot port

 
Rep Power: 786

Damn man you serious? You need to crack that whip boy

 
Rep Power: 786

It is a brief tone played over a system to get an SPL reading

Sounds more like a fart than a burp, but burp is what they call it
