    Yes There are single coil 2 ohms speakers thats the newest version. They have them i 2,4,8 ohms in this series. the dealer close to me only has 2 ohms single coil that why I would like to know how I can hook 3 of them my punch only goes down to 2hms.

You can't run parrallel on 3 single voice coil subwoofers. If you run all the negatives from each coil and possitives from each coil to one terminal you will be dividing the ohms by 3. I don't think JL ever made a single voice coil 2 ohm subwoofer though. If you ran a parrallel on 3 8 ohms you would be at 2.7 ohms. 3 4 ohm would put you down to 1.3

    O ya the new ones are single. I thought you had v2's. You can't do it unfortunately unless you run multiple channels :(.

Infinity 1250 watt dual voice coil wiring diagram


how you wire it depends on your amp, I assume that the sub is a 4ohm DVC from what you have provided.
Parallel:
If you have an amp that can handle a 2ohm stable load you can connect one voice coil + and - to the amp and then run wires across the sub to the other side + to + and - to -

Series:
If your amp won't support 2 ohm you have to run it at 8ohm, to do this you connect from the amp to one + and to the - on the other voice coil on the sub, you then run a single wire between the + and - terminals .

Below are some images to help

I dont how to run the wire on the back of my alpine type r 1242d


you can connect speakers up any way around ,if its one speaker with 4 connections then these extra 2 terminals are often for a continue through to the next speaker along the line ,.just use a small 9v battery and then connect to two terminals to find a bleep as you touch two of the terminals then you know where to put your wires

Id say take it back to where ever you bought it from and get an exchange. Have them test it there and see if it works. I have a JL W6 and have had JL's for a long time.To hear of something like this with a new JL is very rare. Just may be some kind of defect. Bring it back, get it tested and go from there.

How to run wires is series fof 3 subs


If they are single voice coil speakers (1 positive and 1 negative terminal on each speaker) then connect from amps' Positive output terminal to spkr. 1 positive terminal, THEN spkr. 1 neg. terminal to spkr. 2 positive terminal, THEN spkr. 2 negative terminal to spkr. 3 positive terminal, THEN spkr. 3 negative terminal to amps' negative output terminal.

That is 3 speakers wired in series. if each spkr is 2ohms, then you will have a total 6 ohm load. If 4 ohm spkrs., then a total 12 ohm load, if 8 ohm spkr., then a total 24 ohm load.

Be careful because amps do not like these odd ohm load totals. You might get away with a 6 ohm total load. Depends on the amp.

Your amp is stable bridged mono at 2ohms, however, having dual 2ohm voice coils will drop the amp to 1ohm if parallel and will kill it. The cleanest possible way to run this amp and keep it cool with lots of headroom is to run the coice coils in series then run the amp in mono @ 4ohms. To do this, run from one voice coil to another, a jumper. connect positive from one voice coil to the neg of the other voice coil. Then connect the remaning positive on one voice coil and the neg from the other voice coil to your amp (positive left and negative right on the amp) If your amp has a switch for momo make sure it is on, some are automatic. Hope this helps

Is a 15 w3 d-4 better then a jl audio w3-d2


Hello,

All of the JL W3 subwoofers are essentially the same. The "d2" and "d4" suffix refers to the voice coil configuration. "d2" = dual two ohm coils, "d4" = dual four ohm coils. Depending on the number of subwoofers in your system and the amplifier(s) you are using to power them, one or the other of the configurations may be "better".

Generally, you want to have the load on your amp to have the lowest possible impedance consistent with the amps capability to operate properly with that load. It's normally referred to as "impedance matching". Greater power (watts) is produced, and louder sound, when the amp can deliver power at a lower impedance.

If your amp is only capable of supplying power at 4 ohms, you want to make sure that the configuration of your sub(s) represents a 4-ohm load. If the load is higher, say 8 ohms, then your amp can only deliver about half the power of which it is capable. It would be OK to run them a 8 ohms, but they would not be as loud. On the other hand, if the load was lower, say 2 ohms, your amplifier would soon overheat and go into protect mode.

So the trick is to first decide on how many subs you want. Then choose an amp/sub combination that "matches".

The DVC or dual voice coils just gives you more options in selecting and configuring. Say you want 2 subs and you are going with the 15w3 d-2. Your amp is the JL Audio G-MAX monoblock. The amp puts out 1200Wx1 Chan. at 2 ohms or 600Wx1 Chan. at 4 ohms. You would wire both of your subs voice coils in series making each sub 4 ohms, then wire the 2 subs in parallel to your amp making the final load 2 ohms, the best "match" for your amp.

Wiring


Run a Jumper from coil 1 + to coil 2 + and a jumper from coil 1 - to coil 2 - and then run + from coil 1 to amp and - from coil 2 to amp. This will put your load to 3 Ohm and that will give you the most power. You could get more by going to 1 ohm but I don't think the mtx amps are stable at 1 ohm.

Jl subs not powering


Connect each speaker coil one at a time to a square 9 volt battery and watch for the cone to move.

Also try hooking another speaker to your amp just to make sure it isn't in the amp.

You can use a 9 volt battery to test wire polarity also. Hook up the + wire of the speaker to the + terminal of the battery and the - speaker to the - battery terminal. If the speaker moved UP or OUT then the wiring is correct. If it moved IN or DOWN then the + and - wires are backwards on the speaker.

Also if you have two or more speakers hooked together test all the same way while they are hooked to each other. ALL of the speakers need to move in the same direction at the same time.

Clipping causes more speaker damage than anything. "Dirty Power" can happen in good quality amps too. The gain control is to match the voltage between the headunit and the amp. It is NOT a volume or boost knob. If you overdrive the first stage of the amp and then clip it damage will occur to the amp and speakers at some point.

Hope this helps.
