SOURCE: Car Sub JL 12w3 low sound

So I am assuming that you have just setup/wired this up recently? Have you had this working before?
You can have a look at the gain control on the amp & see if this have been set really low. This will help if the signal coming from your stereo is weak. The other thing I would suggest is to make sure that the amp can actually push this sub. I know what the specs say:

  • 1 channel audio amplifier
  • 1 x 350W RMS @ 1.0% THD
  • ThermalThrote full-on power assurance
  • 2 ohms stable (non-bridged mode only)
  • RCA type inputs
  • 0.3-6.0 VRMS input capability
  • Continuously variable High-Pass & Low Pass 50-250 Hz
  • Continuously variable Bass Boost settings (0 tp +12dB)
  • Frequency responce: 10-30,000 Hz
  • S/N >104 dBA at full power @ 0.1% THD
  • >80 dBA at 1W/1M
  • Remote gain control, mounting hardware & screws included
but I don't believe most of these. Many manufacturers embellish what their products can actually do! With the bigger more established brands such as JL Audio you will have no problems, their products have been tried & tested so much on the competition circuit.

SOURCE: already bought jl 12w3 in high output bandpass box

I'm guessing it's a four ohm woofer? They made a 2 and a 6. But for the four ohm the ideal enclosure for high output is 4.374 ft3 minus displacement. The golden ratio is 31.75 x 19.75 x 12.25 in inches; external demensions; using 3/4 MDF. Round port 4" in diam and a length of 13.5" (side port). This box is tuned low at 21.74hz with a F3 of 22.63hz. This box should pound!

I have a box ported with separate chambers with 2 12w3.the problem is it doesnt really have the bass i thought i would have with these subs.the amp is a jl500/1 maybe i need m ore power or maybe its the...


it sounds like ther is a problem somewhere. double check the wiring going to the subs. if one wire is out of phase it will make it sound like no bass... also try pionting subs toward the tailgate. this will make the subs sound better.it could also be the box. jl audio woofers like sealed boxes.

How 2 wire 3 jl audio w6 v2


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.

How do i connect a directed 1100d amp to a jl audio 10w3v2-dual voice coil


Hello disciple_sco,

The 3v2-D4 Jl's have 4ohm voice coils. The 3v2-D2's have 2ohm voice coils. If you have the D4, you should run the voice coils in parallel, both positives and both negatives to the respective amp terminal. This will result in a 2ohm load to the amp. If you have the D2, I'd series the voice coils, jumper one positive to the other negative and connect the other positive and negative to the amp terminals. This will result in a 4ohm load to the amp.

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.

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

Trying to find out wat the watts are on a jlw3 12 and a jlw0 12


The JL 12W0 needs 125 watts RMS. Sealed box it needs 1.5 cubic feet. Ported it needs 2.5 cubic feet.
The JL 12W3 needs 300 watts RMS. Sealed box it needs 1.25 cubic feet. Ported it needs 1.75 cubic feet. I wouldn't suggest running these subs together.

Dimension please for enclosure 12w3v2-d2


Typically you use one cubic foot per sub, so a 2 cubic foot box will work fine. To build a basic one, just a rectangular box, using 3/4" MDF (excellent material for a box), cut pieces this way:

2 - 25.5" x 13.5"
2 - 25.5" x 12"
2 - 12" x 12"

This will give you an interior volume of exactly 2 cubic feet. Cut your sub holes out of one of the 25.5" x 13.5" pieces.

JL AUDIO 12W7-3 SUB


the rottem electronic smell is the voice coil burned up as well as the bad sound, isn't the 1st time i have seen a JL sub blown. not worth fixing buy a new one the cost is not that much more repair on them is 250 - 450 depending on how bad it is and only JL can do the repairs as they dont authorize repair shops access to their voice coils. however i can sell you a new sub with full JL factory warranty drop shipped to your door for about 475$ or I could do you a way better sub ( the baddest competion sub made in the last 5 years) an olympus 2412 dual 2 ohm 5000 watt monster that has user replaceable voice coil options and is killing the competition circuit right now for about $275.00 shipped. it will stomp 2 13 w7's into the ground all day long. 2 subs vs just 1
