So I saw this while I was trying to add knowledge to my little brain and was curious as to how to figure how much power is going to each voice coil.. who can help me out??

uhm... whatever power that amp makes at that ohm load divided by 3 for each sub, divided by 6 for each coil? odd question.

edit.. yellow writing is hard as HELL to see. lol wouldnt that be a 1.34 ohm load?

Edited February 5, 201114 yr by smashedz28

not only odd.. but WTF... what amplifier???

Sorry bout the yellow but its a link from another page. The speakers would actually be dual 1ohm. With lets say a 1500w amp.. We will start there. I didnt think it was an odd question because im not that familiar with how to calculate power distribution, and everything I have read is a little confusing for me.

ok.. first off i dont suggest you go and hook up 3 1OHM DVC subs like that to just any amp. 2nd you just divide. (3) DVC subs has 6 coils..(2 per sub). just say you have 1500 watts.. divided by 3 would be....500 per sub.. or 250 per coil. Im not really understanding why you posted this here, if your trying to put together a system and dont understand give us ALL the info, what amp your using, what subs, what electrical upgrades, and anything else you plan on using. With all the info we can help you in the right direction. If its just a pretend question and you dont plan on using it on anything then there is an answer. divide the power by the coils for a rough estimate of whats going to each coil.

Yes that...

That pic is supposed to represent 2 subs the third is outlined to show that you could keep adding. I didnt make the drawing just used it. My current setup is in my sig. Really what im trying to do is plot on paper an upgrade to my subs. I was thinking bout adding another 10" BL, or going with 2 12" but like I said I want to draw it on paper to look at possible amp/ power options. Your first answer helps. People always think that an answer has to be for a specific setup. Im trying to use a setup that im familiar with to help me understand the concept so that I can make proper plans on paper before I start buying stuff..

Just FYI... That really could've been your initial post... The guidelines get re-posted all the time since all new comers, myself included seem to not advertise what they are making a thread for in terms that all can understand. It can make some people annoyed but I'm too new to have that feeling... ...

I'd also like to ask what do you have room for in your vehicle? Also what vehicle is it?

I though my sig would explain my current setup under "current".. My original question was about HOW to figure out the power going to that setup (like with a formula). The amp could be 100w, 1000w or even 100,000w, but if I dont know how to figure it (ie what formula to use) then I have to get on here and try to squeeze answers out of the users (which im very great full for ). And to please the masses my experience is a few years and installs under my belt but they were all BASIC installs and im getting into more intricate installs (especially in my ride). That did answer my question tho so thanks. Now I can play around with a few configurations to see if I want to use the same amp or get another..

LOL that is what I got and are getting. I have plenty of room but are trying to keep some room in the back..

Actually thanks to both of you Shogen and smashedz28. I work in a field that is not car audio or even related to car audio so its all Chinese arithmetic to me..

If it were me, and I was "needing" more output..(notice the quotation marks) lol... I would add an additional subwoofer and call it a day... This would require you to add more or change your current amplifier and get a new enclosure. I think all those items involved are enough to consider alot of work and a meaningful upgrade... Don't you?

I fix computers and remove people's viruses they get from trying to get free everything online... It has nothing to do with car audio, I am an enthusiast I guess... Somewhat addicted and still learning...

Needing.. If im paying for it, its always a need

I know it will require some extra equipment but thats why im doing it on paper. Besides I aint doing anything more until the DC power guys can get my car in to mock up an alt bracket..

So I saw this while I was trying to add knowledge to my little brain and was curious as to how to figure how much power is going to each voice coil.. who can help me out??

The simple answer is that if each coil is the same resistance, then each coil will receive 1/4 of the power output from the amplifier.

Or did you want the math behind it?

Well, I'm bored, so we're going to go through the math anyways.

Let's say you have a 1000w amp and two dual 2ohm subwoofers wired to a final 2ohm load. First, let's find out the total voltage and current output of the amplifier. Using basic ohm's law, we find:

Voltage = sqrt(voltage * resistance) = sqrt(1000*2) = 44.72V

Current = Watts/Volts = 1000/44.72 = 22.36A

And, to verify we are right, 44.72 * 22.36 = 1000w.

Cool, step 1 complete.

Now let's find out out much voltage and current each speaker is receiving. Let's just look at the two drivers on the "whole", forget about individual coils right now. Each driver is 4ohm (since the individual coils are wired in series) and the two drivers are wired in parallel. One thing we know about parallel circuits is that the voltage is the same across the resistors, so we know each driver is going to be seeing 44.72V. To figure out how much current each driver is going to see, we divide the voltage by their resistance;

Current = Volt/Resistance = 44.72/4 = 11.18A

So how much power is each driver receiving? Simply multiple voltage and current; 44.72V * 11.18A = 500w.

Cool, so we know each driver is going to see 500w.

Now, how much power is each coil going to receive? Well, in a series circuit, the voltage is "split" between the resistors and current stays the same. So current to each coil is 11.18A.

Voltage = Amps * Resistance = 11.18 * 2 = 22.36V

And power to each coil is voltage multiplied by current; 22.36 * 11.18 = 250w to each individual coil.

So, there it is. Basic Ohms Law. Each coil will receive 250w.

Or, since all of the "resistors" (coils) are the same resistance......we can skip all of that headache and just divide the power by the number of coils; 1000/4 = 250w.

You would really only need to bust out Ohms Law to figure this out if you had drivers that were different impedances. And then it gets a little more hairy.

Now thats all I wanted. Simple answer to a simple question. the math is too Gee Wiz for me but good shit..
