I don't know the math on adding more speakers, but I am nearly positive that it doesn't flat out double the volume. I don't think it even results in much more volume at all. Don't bother using google and reading forums... it is full of idiots who think they can run like 75 speakers and get 300 db from 20 watts. Or people who are like "well you don't get double the SPL, but you do get +3db"... every 3db IS double the spl. Car stereo forums are almost worthless for this kind of information.

There is a nice calculator somewhere that lets you get estimated SPL levels from multiple speakers and different wattages and stuff. It assumes by default that if you add another speaker, you add corresponding wattage to it. If you say put in 2 10" speakers at 100w, then double the speakers.... it assumes again another 100w. If you cut the base wattage to 50 so the TOTAL is 100w, you will find the SPL is given as the same as the first two speakers at 100w. Simple fact is that you need to provide the power.

Doubling the surface area only helps increase a speaker's ability to produce low end frequencies at spl levels we can hear. For higher frequencies, the effect seems to be lost. Basically, you have to move more air around for the human ear to pick up lower tones more efficiently. This is why 10" subs have a really hard time hitting as low as a big 15".

At any rate, +3db = double the SPL (sound pressure level, which is basically a fancy version of db), which costs double the wattage. And peak power measurements are LOL.

It was always my favorite thing to roll around with this 600 rms sony xplod amp hooked up to two 15" MA Audio subs. They got loud as hell, people would be like "

DAMN MAN YOU GOT LIKE THREE THOUSAND WATTS BRO?

Or, if I told them I was running "600 watts", others would be like 'PFFT BRO THATS WEAK I RUN TWO THOUSAND" and then they show me their Pyle Audio amp, rated for something stupid like 2kw peak @18v x 1ohm with 10% THD... while they run 4 ohm speakers in series at 12.8v... Yeah, good luck with that 200 rms bro.

I facepalmed every time.

Decibels is a logarithmic scale, +3dB ~ 2x power, +10dB = 10x power.

Talking about audio, here is my mod on 2009 where I made my own analog stage of CS4398 out from X-Fi Elite Pro and build it in accordance to CS4398 datasheet, but not the exact resistor value since it uses precision 1% ones, I just made this out of cheap 5% I could buy for few cents. This actually makes it miles ahead of anything I heard from any soundcard since, never heard anything sound this smooth and the sundstage is just amazing. Mind you I'm using Monitor Audio speaker with Technics amp and not run of the mill PC speaker. Too bad Creative cards don't last long because of crappy caps they using

Running external power from modified cheap PSU with high quality caps

Sweet mercy, that is quite a rat's nest.
Not sure where the power supply is. But great job anyway. I was even thinking about something similar(gaming server + file sharing server in one case).

heres one for you all , basically i have a stand in graphics card (nvidia g210 1gb zotac) some of you may know that this little card does not allow fan controll.. when running the fan would always be at 100% etc causing alot of noise.

on the same computer i usually leave it on dawn till dusk hosting a tekkit server for a few friends but id like to keep it on over night, so i sat thinking then i came up with this:

i went from this little thing:

to a third party 58xx cooler using cable ties

now back to silent but pump noise ..
idle temps were around 58*C now there at 41*C
