Posted November 19, 201113 yr To burp a sub would I just go wth a bigger amp and turn the gain up and give it a burst for 5 seconds or so?
November 19, 201113 yr Author is a bibber amp?I'm going to take a guess and say "bigger" yes damn fingers.
November 19, 201113 yr Okay."Burping" is just a term people made up when running excessive amounts of power to subwoofers for a short period of time.Normally burping is done for SPL competitions, say your run is thirty seconds (I don't remember what the run lengths are for: meca or usaci), so you pull up in the lane and they say go. You have thirty seconds to play what you think will meter the highest.Most subwoofers can handle double, triple, etc their rms rating in short short periods of time. If the time length is short enough then the coils don't really get a chance to heat up, so to speak.This allows you to use a bigger amp, more power, and get more output for your runs on the mete. For daily it means absolutely nothing except a cooked coil if your an idiot and don't bring down the power.I hope that makes sense.

Time length of run, power used, enclosure, amplifier settings.I could see one person burp the same driver without ever needing recones for several years, while another person completely melts the coils and needs a recone in five minutes.

November 19, 201113 yr There are lots of different ways to compete, read the rulebooks, and use some common sense.I never geared my setup for competing, but I did like to show up and just for kicks see what my daily driver was able to pull off. Of course a larger amplifier and higher tuned enclosure would have raised me an easy 5dbs, but I wasn't serious about comps.If you are indeed serious about competing, you need to be able to build enclosures for yourself, and have access to an accurate meter for testing purposes.
November 19, 201113 yr Burp usually means running a "Tone" instead of music for roughly 30 seconds.Yeah I guess I should have just said that. :facepalm:

November 19, 201113 yr Yea but not for 30 seconds!User just has a window of 30seconds to post their best score...On a meter, 2-3 full seconds is PLENTY to get maximum pressure reading.When running a lot more power than recommended, the shorter the better.. but that's trial and error to figure out yourself.There are only 2 things a user needs to control when burping-Mechanical movement and Thermal environment.Thermal is easy, do a burp, should be fine as long as it's 2-3 seconds only (let cool down after the burp)Mechanical- do not let the sub bottom out, do not let it leave the gap, if your motor doesn't have a pole vent, you may blow your dustcap off(if this happens, replace dustcap and drill small holes in it next time)I know you probably haven't heard about hardly any of this.. welcome to competing,

November 19, 201113 yr Burping doesn't have to be 2x-3x the rated power either. It can be anything. And there are MANY ways to compete. db Drag Rule BookUSACi Rule BookNESPL Rule BookMECA SPL Rule Book
