Ok, first off I have a JBL 1200.1 which has 2 positive terminals, and 2 negative terminals but it is a monoblock amp. Then on the subs, which are Audiobahn AW1206q's They have 4 terminals on each side of the sub. 2 positive terminals and 2 negative terminals on each side, IT looks like for every 2 they are connected and go into one to the voice coil. Now that means there is 8 total terminals on the subs. 4 positive and 4 negative. I have 2 of these subs. I also have 4 terminals on the box for each sub. meaning i have 8 total terminals on the sub box. and now i have 2 positives, and 2 negatives on the amp how do i wire this up, the amp can support 1 ohm mono so thats no problem. Here are a few pics to help.
These are the 4 terminals on each side 2 positives, and 2 negatives.

 

The set of terminals on the sub totalling 8.

 

The terminals that look like they go into 1 wire that goes to the voice coil.

 

side of the amp with its 4 terminals

 

And one of these per sub on the side of the box

 

and a little wiring schematic that might help or hinder... yes my hand writing sucks.

 

there are 2 basic ways you can wire it, and get either 1 ohm, or 4 ohms. for one ohm, just run all 4 vc's into the amp, just make sure you get the phase right. the other way, you will run pos on one coil, and neg on the other, then cross the remaining 2 terminals, and you will need to do that on each sub.

 

Ok, I had all the positives from one sub ran to one pos on the amp, and all the negatives from the same sub hooked up to the corresponding negative on the amp. I then hooked the other sub up the same way using the other terminals on the amp, after about 3 minutes You can smell the voice coils melting.

 

on your terminals, you don't acutally need to use all eight. you only need to use 4. 1 pos on each coil, and 1 neg on each coil. if you hook wires into all 8, you're prolly causing some kind of electrical arcing.

 

i'll take that into consideration, thanks.

 

no problem, i know it can be a pain in the **** to wire up dvc's at times. it was a little fun to figure out when i started getting into systems. the subs in the picture on my post are dvc's, have them wired up for 8 ohm per sub.

 

ummm...I'm not sure if I got what you were saying right, but I want to make sure you don't put too much wear on the voice coils by having them wired up wrong and fighting each other.

You actually have a lot of choices on what ohms you want to run. 1, 2, 4 or 8. You achieve this by wiring the subs and voice coils together in series or parrallel. Just in case you forgot how each of those run from highschool physics, here it is:



Now, these voice coils act as resistors(hence they are measured in ohms), so when hooked up in series you add them together, and when hooked up in parrallel you add the reciprocals.

>hooking up two 2 ohm voice coils you get:

series = 4 + 4 = 8 ohm or x + x

parrallel = 1/4 + 1/4 = 2/4 .... then 4/2 = 2 ohm or 1/x + 1/x


So, minimum resistance (lowest ohms) that you can achieve would be to put it all in parrallel. Two 2 ohm voice coils in parralel will give you a 1 ohm resistance, then both subs hooked together parrallel running at 1 ohm will give you a half ohm line. Not good lol.

The same goes for series though, Two subs hooked together in series with series dual voice coils, will grant you an 8 ohm line.

I think you are trying to run at 2 or 4 ohms, so you are going to have to mix the series and parrallel connections...

For a 2 ohm connection, run all the voice coils in series with each other, then run the subs in parrallel. IF you want to run around 1300-1400 RMS watts across the subs. It's done like this:




(Since the JBL 1200.1 is a mono
amp, running it like this is just like
hooking the positive and negative
from each sub into the same "spot"
or "channel" on the amp, making it
a parrallel connection.)


On the other hand, if you want to run the subs at 4 ohms, at which the sub will push 600-700 RMS watts it will be a little different, and a bit more complicated wiring. Backwards actually:



Now that everyone has learned all they didn't want to know about electrical circuits today, I hope it helps you guys out who have dual voice coil subs.

 

These pictures are for the post above.

 

I think the major confusion is that you have 8 terminals on each sub. You have 2 + and 2 - on each side. The only reason for this is to make it easier for you to wire them. Each side is one voice coil. The reason they have two terminals on each side is so that you don't have to cram a bunch of wire into one terminal. Think of it as an input and an output. If you wanted to wire each voice coil in parallel then you would run a + and - wire to one side of the sub using one of the terminals. Then you would take a short peice of wire and connect them to the other + and - terminal on the same side that you hooked the amp to. The short wires are your outputs to the other voice coil. So in parallel, you would run the + output wire to the + terminal on the other side of the sub and the - output wire to the - terminal on the other side of the sub. Thats it. Do not hook the amp up to the other side of the sub. In this case you will have only used 6 of the terminals. This is a 2 ohm load for your sub. Now if you want to make a 1 ohm load, you can do it two ways. First you can wire the second sub the same way that you did the first and hook the end to the amp in the exact same location as the first sub. This can crowd the wire in the amps terminals. The other way uses the extra terminals the Audiobahn puts on the voice coils. You will use the 2 terminals left on the first sub and run wires from it to the other sub. Those two wires will be the inputs for the second sub. Connect the + wire from the 1st sub to the + terminal of the 2nd and - from 1st to - of 2nd sub. On the same side of the second sub you will want to run wries from the first voice coil over to the other one. + to + and - to -, just like the first sub. So basically you have one wire running to all the + and one wire running to all the -. I hope this helps. Good luck

 

Another pic.

 

Last one, thank ***! Now, you can read my post with working pictures.

 

OIC...duh. I totally missed that 8 terminals per sub thing going on. I would think those are there for ease of hooking up miltiple amps to one sub. I guess some people don't like to run wires from amp to amp, so you could simply have the two amps go right to the sub. Cool.

 

One thing that you may want to keep in mind is the load the each channel of the amp see's. If you bridge a 1 ohm load across two channels the way that it is shown in Proximo's picture, then each channel will see a .5 ohm load. Maybe too much for you amp. You will want to set your subs up in a 4ohm configuration and then bridge that across the two channels for a 2 ohm load each, or wire the voice coils in parallel on each sub and run one sub with one channel giving you 2ohm load on each channel. I hope I'm not cunfusing you. Good luck.

 

I just noticed that there is a bus bar connecting both the +'s and both -'s on your speaker box terminals. If you want to wire those voice coils in series, you will have to remove those.

 

The JBL 1200.1 amp is a mono amp, so when hooking a sub into each "channel" you might as well be hooking them into the same terminals.

I didn't make a picture for the 1 ohm setup, but I just realized that where I said you could get 4 ohms, I was wrong...that one is running at 2 ohms as well. Heh, I did that late at night.

 

so this one is for 2 ohms?

 

That is a 4 ohm load. Across your 1 channel output, it will see 4 ohms. With the subs that you have, if you want to power both voice coils on the subs, you basically have two choices. Either 1ohm or 4ohm loads. The choice is up to you.

 

If the 1200.1 is a mono amp, which it is, why do the diagrams show it having two outputs. That is confusing. Is that a diagram from JBL?

 

the two outputs are internally connected. its just to faciliate wiring stuff, makes it real simple to connect 2 subs in parallel

 

Yeah, its just to simplify wiring...I made the pictures to look like it would look as you wired it up. And I made those pics in Adobe Photoshop. Both of the actual wiring diagrams put a 2 ohm load on the amp. The reason I was adding it up wrong at first, is because I was calculating the parrallel wiring wrong.

It's NOT:....1/x + 1/x = 2/x = the load

it IS:....1/x +1/x = 2/x .... then take the reciprocal x/2 is the load


thus, either way you wire it up, you will get 2 ohm loads. Unless you go series all the way through to get an 8 ohm load. And you don't want a 1/2 ohm load(from parrallel all the way). Really.

 

Ok, your subs are a 3 ohm dvc, so you can go at 1.5 or 6 ohms per sub. Which means that you could go with either a .75 ohm load, or a 3 ohm load. Which in theory would give you prolly about watts for 3 ohm, or somewhere about 2600 or so in .75 ohm.

 

so what is the ohm rating on this setup? using dual 4 ohm vioce coils.

 

That is 4 ohms across your one channel. Two 8ohm loads in parallel.

1/(1/8 + 1/8) = 1/(2/8) = 1/(1/4) = 4ohm

 

The subs are dvc's rated at 3ohms per coil. so you can run each sub at 6 ohms, or 1.5 ohms, not 2, 4, or 8. You can easily wire them to your amp to run at either 3 ohms or 0.75 ohms. I would say that 3 ohms would be your best bet.

 

Screamer : thats only a 4 ohm setup if the amp is mono, for example the JBL 1200.1, otherwise you have 8 ohms to each channel.

 

I think you are a little confused about the subs. Here is the link to Audiobahn and their sub specs. The AW1206Q's are dual 4ohm.

http://www.audiobahninc.com/index_noflash.asp

 

we're not talking about the audiobahn's anymore.

but on a side note...some audio seller's say that that sub IS 3-ohm...why the confusion? Are the older models 3-ohm, and the new ones 4-ohm?

Why would they be sold as 3-ohm subs if they weren't? I even read some comments on them, and they talk about hooking them up at 1.5 ohms and such....very interesting. I would personally call Audiobahn and ask them to be sure, if I had audiobahn subs.

 

I'll be d@mned. Last time I read anytihng on the Flame Q's they were rating them at 3 ohms per coil, my bad. I think I can get part of the article where I read it.

Here
With hot looks and hot performance, this Audiobahn Flame Q subwoofer is an incredible addition to your sound system. The 12" 1206Q features dual 3-ohm voice coils (make sure your amp is stable down to 1-1/2 ohms before wiring in parallel), and double stacked, 120 oz. strontium magnets that handle all the power you want.

 

.......OH NO I'VE GONE CROSS-EYED.....:lala: :lala: :lala:

 

lmao

 

But why does Audiobahn's own webpage say 4-ohm? If they are wrong, then they need to get it together man! (or fire their webmaster!)
