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.

Whats the best way to wire an mtx thunder152 to an jl audio 12 w3-d6 duel voice coil sub


Take both positive leads to the positive of the amp. Both negatives from the sub to the negative of the amp. Utilize the bridged output connections. This would present a 3 ohm load which would be around 100 watts rms (rough estimate)

You may have touching speaker leads going into the amp. Make sure the tinsel is not touching across the speaker inputs on the amp. Also check your ground. It should be solidly connected to the vehicle chassis in a paint-free location. Finally, make sure there are no exposed speaker wires touching the vehicle chassis.

How can i make my jl audio 12w3-d6 into a 4 ohms


it depends if the amp is mono or stereo and if it is bridged. if it is bridged the amp cant handle the speaker the best way is to lower the level on the amp or connect it to only one channel. also you might want to check your ground cable use a thick one and make sure its making good contact with the chassis. this happened to me. luck

Can i hook up a powered 12'sub to a Pheonix Gold xs2500 amp without blowing the speaker


First I hope you remove the speaker wires from the speaker that come from the built in amplifire. You cannot hook the powered sub to the amp without doing that first. Then all you need to do is run speaker wire from the sub out of the box to the amp. In no way can you hook up any other part of the powered sub, but the sub itself, to the amp. If you know the wattage of the sub and the ohms then wire it to the amp correctly. Your phoenix amp will put out 125 watts x 2 at 4 ohms and 250 watts x 2 at 2 ohms and 500 watts x 1 at 4 ohms bridged. Remember, only the sub itself in the sub enclosure can be connected to the amp. Hope this helped you. Let me know if you need more help.

2 ohm speakers wont work on a lanzar max pro 4000 watt


The 2 ohm stable rating on the amp is PER channel meaning that you could effectively hook up a 2 ohm speaker or a 2 ohm load to each channel without the amp getting f"d up-butin bridged mode it will only be 4 ohm stable. to achieve a 4 ohm load with your sub the type x wire the coils in series that will get you at 4 ohms to run in bridged mono .But you will get the exact same amount of power if you wire each coil to one channel of the amp as bridged mono sees the sum of your 2 ohm channels combined-Hope that 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.

Three jl w3 single coil


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

Check the ohm measurement of the speakers make sure they are about the rated ohms.Check them UNHOOKED from the amp. (Useually 4 ohms.)

Try different subs.
