So i got a speaker box...
It comes with the little thing in the back where you put the (+) and (-) wires at..
How exactly do you hook a DVC sub to this? Or can you?

So there is no way for me to run all wires into the amp without putting them in series or parallel?
Since each coil is 2 ohms, running them in a parallel would basically result in a 2 ohm speaker?
So this means the other channel in my 2 chan amp i bought is going to be useless since i dont plan on getting another sub..
The sub i got was 250 RMS @ 4 ohms..
So running it in a parallel would mean 125 RMS @ 2 ohms or 250 RMS @ 2 ohms?
The amp runs
# 200 Watts RMS x 1 @ 4 ohms
# 100 Watts RMS x 2 @ 2 ohms
Im thinking of just taking out the black piece that holds the 2 wires from speaker and making the holes bigger, so all 4 wires can fit through.
I specifically got the amp for that sub, and it just pisses me off i wont be able to use it how i planned on doing so

Actually..
The sub would be 250 RMS @ 1 ohm and the amp isnt even 1 ohm stablized if ran in a parallel.
What ohms would the sub be if ran in a series hook up

You can run the wires for each coil to the amplifier. The thing to remember is you have to use both coils in a DVC. You can bridge the amp and use a mono signal, if the amp is able to do so. If you have a 2 ohm DVC, the parallel impedance would be 1 ohm and the series impedance would be 4 ohms. When I ran a single DVC, the 4 ohm DVC was a better fit since the parallel impedance was 2 ohm and the amp was stable at 2 ohm.

Parallel hook up is almost out of the question, since i dont plan to run the sub at 1 ohm impedance..
Question about the series hook up though.. Its basically 1 (+) from the left side and 1 (-)coil from the right side correct? Since the impedance would be the same, does that mean the amp would have to push the sub twice as hard since only one half of the voice coils is actually being used?

Since you amp is 200 Watts x 1 @ 4 Ohm, just wire the speaker coils in series. That is, run the positive from one coil to the amp and the negative from the other coil to the amp. Then jumper the other positive and negative of the coils together. That would put 100 Watts to each coil since you have to use both coils.

So basically, in a series i would be running the same wattage as using all 4 wires to bridge into a 2 chan amp?
What exactly do you use to "jumper" the other (+) and (-), i know those 2 dont go into the amp just wondering on how to actually cancel them out or w/e

the best way to o the one on the far right would be to have 2 + and two _ come from each bridged port on the amp and send one to each of the spesker box ports. assuming the dvc is wired series parallel liek in the pic
lawl dint realize how horrible of a drawer i am hehe

ok you have 2 sets of black and red connectiosn ont he speaker.. those are the dual voice coils
You take one red and one black and connect them with a single seperate wire. Then you take a wire and connect the red w/o a wire attached to it and connect it to the red on the box. Then do the same for the black. THEN.. outside the box.. you simply hook it up to the amp.
Just like in the speaker above.. that inner pair are conencted by a wire... then that outside pair you attach to the inside box connectors.

O fak...just remembered the amp only pushes like 50 RMS @ 4 ohms X 2...
Looks like ill have to run all 4 wires into 2 channels, i guess ill drill a hole into this

Ok so in your situation you will want to do the series wiring. Where you bridge your 2 channel amp. Making it so that the outer 2 connections... one is + the other - each will have a wire going off of it going to the box. Then inside the box you will have the dvc speaker.. with 4 single wires... 1 single wire connecting the 2 (-)'s together, and then 1 single wire connecting the 2 (+)'s together. Then take 1 single wire and connect the + of one voice coil to the + of the box or connect it to the + coming from the amp. Then on the other voice coil hve a single wire coming off the (-) and have it connect to the - coming from the amp. That will give you a bridged 2 ohm connection. For your single sub with 4 ohm dvc. Whew lawl.

Sooo.. in the end you will have a bridged amp running a 2 ohm load.. pushing 200 w rms. 50 @ 4 ohm x2.. bridged to x1 is 100 w... then going into 2 ohm.. doubles it again.. 200 w... or so I am pretty sure hehe

I hope 18 feet of sub wiring is enough to do what you just said, assuming your theory is correct.
I might just screw the amp down on top of the box, so a wire from sub --> amp would only be like 2.5 feet or so
