Wiring Kenwood KFC-W3003


If it's a single voice coil, it's probably 4 ohms. the sub only handles about 175w RMS, so don't expect earth shattering bass to come out of it. A single voice coil is easy. Positive from the amp to the positive post of the sub, negative from the amp to negative post of the sub. This sub sounds lots better if it's in a sealed enclosure. A ported enclosure allows too much cone movement, heating up the coils, and the sub fails prematurely. Hope this helps.

I think its my voice coil but I might as well ask to make sure. At higher volumes, my W7 will make a wierd rattling sound from inside the sub. Is it the voice coil or something else?


tinsel lead on terminal needs to be coated with a layer of black rtv sealant where it comes out of voice coil on back of speaker temporary fix since you have OVERPLAYED your subs,

How can i connect 2 12''s pioneer premier too an jl audio amp n make the bass loud???


Hello m1k377060,

Having your subs in well-designed and constructed enclosures will make as much or more difference in their output than how you connect them to an amp.

The TS-SW1241D's are single voice coil 4 ohm shallow subwoofers that are rated for 350 watts RMS. For maximum loudness, your JL amp needs to be 2 ohm stable and capable of delivering 700 watts RMS into that impedance. Wire the subs in parallel for a 2 ohm load and maximum power from the amp.

Hope this helps.

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.

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.

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

Jl audio 12w3v4....both smoked and fried on a 500/ jl amp


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.....
