ohm load?

I would suggest hooking up at least two amplifiers.  Its going to be real hard to find an amp that will put out enough power for eight subs...You can run 4 subs in series/parallel for a 2ohm load on each amp...You could also run 4 amps @ 2ohms each...

List the number of subs and the voice coils. I can then give you a diagnosis of how to attack this disease.

they are dual 4 ohm voice coils, i know that i could hook 8 of them up to 2 amps and run them at 2 ohms to each amp, but i was wondering what else i could do becuse im not saying 8 is what i want, if i can do more than i want to do more, i would really liketo run them all of one amp so thats why i need a chart or somoene to tell me how to do the math in order to do it.

i was thinking between 6-10 subs. is there anyone that can help?

The most helpful thing might be to learn how to calculate parallel and series resistance. Once you have that down, you can figure out how you want your final load regardless of the amount of speakers. It just seems to me that you are asking for a lot of time involved in mapping out the possible configurations for 6 to 10 DVC subs. Of course, I could be wrong, there may be a chart out there....or someone may have the time to map it out for you.

"Give a man a fish, feed him for a day..."

well that amp i was thinking of using is an phd5000 which i think is more power than i will need, but that is besides the point and i know that it is going to be pricey and that is why im trying to figure out to go with that amp or do i need more than one amp.

and flakman if you would read what i wrote before i simply asked someone if they could tell me how to calculate the series and parallel resistance then i would not be having this problem, so if you know it then i would like to kno what it is so i can do the math myself and figure it all out. im not asking other people to really do it for me im just asking for the formula to do it.

Understodd oxygen.

Series is easy, simply add up the resistance. R1 + R2 + R3 = Total R  (4 + 4 + 4=12)

Parallel is a little more complicated.   1/(1/R1 + 1/R2 + 1/R3) = Total R  1/(1/4 + 1/4 + 1/4) = 1.33   An easy way that may help is, when having two of the same resistance paralleled, their resistance is than halved. 2 - 4 ohm VC would equal 2 ohm. To maintain a 4 ohm load with 4 ohm DVC subs: Wire both VCs of each speaker in series to make both speakers 8 ohm total. Then wire them together in parallel to bring the set of two subs down to 4 ohms.

I don't know if that was clear enough...maybe someone can word it better. I keep reading it and not liking how I wrote it. Maybe it's just me. Let me know.

I use the12volt's parallel calculator (linked above) all the time;  with subs, and also when figuring out how to bundle resistors for a desired resistance.  When you want to figure out all the possibilities for wiring a number of drivers, think in groups.  For example, six subs could be two groups of three, or three groups of two.  Eight subs could be two groups of four or four groups of two.  Nine subs could only be three groups of three...you're thinking of any number that is equally divisible into your intended target number.

Use both calculators for parallel and series, and go through the possibilities, trying a group in series and then paralleling the groups.  Then do it vise versa.  If you're anything like me, you would use a paper and pencil to jot down rough sketches of configurations as you go.

Thanks stevdart. I was looking for something like that to explain what I was thinking.

Oxygen, JL was telling you to run parallel only. We are trying to get you to run them series/parallel. It will take some sketching out, and as stevdart said, grouping will help to make it easier.

what i think im gonna do is 12 subs total and just run them in 2 groups of 6 making a 1.3 ohm load on the amps
