I have 2 jl audio 12w6 and one jl audio 500/1 amp, and the speakers make a weird noise..sounds like the voice coils are bad..so my question, is there any way i can fix them or i need new speakers?

Blown voice coil,,,,it was connected to a JL AUDIO amp correct? w7`s can ONLY be powered by JL amps due to ohm load.Advice buy a better quality sub,w7 is over-rated

You will have to take a piece of speaker wire and put it from the positive of one voice coil to the negative of the other voice coil.....Then, with the other remaining positive and negative, hook it up to the amp.....And your good to go....If your still confused, get back to me....hope that helps.....

That popping noise is your speaker telling you to turn it down, and that your amp is too powerful for your setup. The speaker cone is moving beyond its limits of excursion and on it's way to malfunction/blown. Basically the voice coil will fry.

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

Hello shermalestuc,

The JL Audio 12w6 v2-D4 has dual 4 ohm voice coils that can be wired for either a final load to the amp of 2 ohms (parallel) or 8 ohms (series).

If your amp is 2 ohm stable, the best power solution for a single sub is to use the parallel configuration, both positives and both negatives together and then to the amp.

Hello mikey4569mky,

Unless your amp is stable below 1 ohm, there's really only one wiring solution. And that is to series the voice coils making each sub 8 ohms, then parallel all 3 subs to the amp for a 2.67 ohm load. If you parallel the voice coils and then parallel the subs, the impedance will be 0.67 ohms, much too low for most amps.

You could parallel the voice coils and then series the subs for a 6 ohm load, but the amp won't put as many watts into a 6 ohm load. Most are optimized for 4 ohms or 2 ohms. And it's not good to run subs in series anyway.

Here's the wiring diagram.

Hope this helps.

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

I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.

Unfortunately, it sounds like the voice coils burnt up. There are places that do repair, but for these particular subs, it would be more cost efficient to replace them. I also doubt they are salable, but ebay is a magical place.....

best way to do this to preserve your amp and speaker is to wire the speaker Voice coils in series.

VC1 = Voice coil 1

AMP + to VC1 +
VC1 - to VC2 +
VC2 - to Amp -

Set you amps bass gain down very low. Crank up the volume with a bass test audio track. Turn the switch to LPF or Low pass filter. Adjust a LPF to about 60 hz Adjust the bass gain up until your Sub begins to sound sitorted or choppy. Then tune the bass gain just below where it distorts. Then you are set.
