Boon Posted February 28, 2009 Report Share Posted February 28, 2009 As mentioned, theoretical rule is that doubling power = +3dB I've also seen it gain anywhere from 0dB to 4dB and change to even losing dB... Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...

01xtreme Posted March 2, 2009 Report Share Posted March 2, 2009 (edited) Too many variables to determine exactly what it takes to go up 1 db in a vehicle. It's all just testing, and tuning. Like said earlier, increasing in 3db's in double in volume, so 147 with 2 12's and 3kw would mean you need 4 12's and 6kw to do 150 (just throwing out numbers), all things held constant. However, even that isn't a law, or you can gain even more by building a new box that is tuned differently, or built to be more efficient.

Kasey Posted March 3, 2009 Report Share Posted March 3, 2009 (edited) Most people think Wen you turn up the volume all your doing is adding more power but for every db you go up you have to double the power. for example lets say that your stereo does a 145 if you want to go to a 148 you have to double the power Edited March 4, 2009 by 916PublicEnemy2 Quote "Audio is not a hobby it's a lifestyle" _____________________________Refs_1_Refs_2_____________________________ Link to comment Share on other sites More sharing options...

Stephen Posted March 3, 2009 Report Share Posted March 3, 2009 Not quite, 3dB = doubling in power 10dB = doubling in perceived loudness, humans have logarithmic ears... yup Quote you can cook bacon shirtless if you're not a pussy...lol not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.

Torres Posted March 3, 2009 Report Share Posted March 3, 2009 (edited) normal rule of thumb is a 3db increase when you double power, but thats in a perfect world as well as doubling cone area As mentioned, theoretical rule is that doubling power = +3dBI've also seen it gain anywhere from 0dB to 4dB and change to even losing dB... i knew a guy who doubled power (i think...might have just added a lot more power) and said his score actually went down. from what i understand, every 3 db's is twice as loud (but as said, not to the ears) so you cant just go adding 1000 watts to gain a db, or else there'd be no end to it. i mean...look at the people who run 100,000 watt burp machines. say...if they hit 150 with 5000 watts. they'd only need 20,000 more watts to hit a 170 using his theory. steve himself has 20k watts and hits mid to high 150's, nowhere NEAR a 170. imo...once you get to a certain level, a 158 is nowhere near a 159, or 160 since it will take SO MUCH work and tweaking and power and whatnot to get that next db Edited March 3, 2009 by ExpoSport Quote Link to comment Share on other sites More sharing options...
