hey is a burp, when you turn up you stereo as loud as you can for a short period of time in a competition? if not , can someone give me the true deff. of a car audio burp?

It's when you have your stereo to whatever volume you want it at. Then you *usually* would use a test tone of the note you'd wanna play ie 45hz. So you close the door to your car and stand outside. When the run starts you unpause the track and have it play for 3-5 seconds until you get a reading on the mic and then you pause it again.
That's what you call a burp. Just a short spurt using using a test tone.
Called a burp because it kinda sounds like one [img]tongue.gif[/img]

just pause your deck, turn it up while paused and un pause for about 3 seconds. all this while using a test tone. there is your burp

ok...is there a high risk of blowing your subs doing this?

no... you have a guranteed risk of blowing your subs .. at least in the hardcore spl vehicles.

alot of subs get blown up in spl competitions, atleast in the hardcore vehicles where they send 10,000 watts to a 2,000 watt subwoofer

that was actually a really common question...
when i first started it took me a long time before i figured out what a burp was. but now that i've come to learn more of the terminology, i'm not shy to ask if i don't know something.

there are no stupid questions here.
only stupid answers (and the odd time stupid people)

Burp and I thought thats was somthing I did after an beer! Yes basicaly an test tone at volume to get results from what ever test equipment on hand. An lot of us older guys know what we can do ( kinda ) because we test to death befor we compeat. Being at full volume isn't allways the answer. I feel your pain but we all need to learn some time.

You can also sometimes send like twice as much power to the sub.
Since it usually won't be over heating within that little time (unless you put too much to it) it will be fine (also depends on equipment).
dB Don told me my x-one can handle about 1000wrms on burps, and its only a 600 wrms sub.
But be careful, don't blame me if your sub catches on fire [img]tongue.gif[/img]
