    appreciate the insight and ill consider the sub offer, but thing is i have invested so much money into jl audio as of now that im not ready to bail out, cause honestly it was operater failure that lead to this subs demise. I let someone use my ride and this is how it come back. Person after person thinks that they can just get in sit down and crank it up and well you know as i do this is not true.



    Some people dont have any business operating others equipment. and jl audio says 410.00 to replace all moving parts on the sub, basically be getting a new sub minus my basket and magnet and not including shipping of course. This sucks, ill consider the sub you have you say it has a warranty.

The smell and sound are the voice-coil having become delaminated and unravelled - usually due to a clipped signal.

The 'watt' is a thermal measurement.

To prevent this failure in the future, I'd suggest viewing a tutorial on setting your amplifier's gains properly.

In fact, JL Audio has a nice, flash-based tutorial on it.

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

    yes it has the full manufacturers warranty on it, i recieve it drop shipped straight from the distributor or i can have it drop shipped straight to you. with the invoice that we both get a copy of, you have a full factory warranty through me my distributor or JL direct. the sub retails for almost $800 so its a little over 1/2 of retail and only 50$ more than sending it in (and paying shipping to send it in which is about $20) if you want i can get you some warranty info from JL.

    let me know what you want to do.

    all JL products are tracked by serial numbers that match up to what business sold it and when they sold it, so JL will already have the new item serial number sold date as soon as you buy it (if you buy it) and they can honor any warranty claim directly or like i said before, I can go through them for you with a simple email from you.



    BTW if you repair the sub you still dont have any warranty at all.

I want to make my own speaker box for a 12w7 jl


you should be able to get the speaker specifications from JL's website. There will likely be a range of box size, for example 0.75 - 1.1 cubic feet. You have to take into account how much power you are giving them as well. Usually with a stronger amp you can use a smaller box as the backpressure will keep from overexcursion but produce a stronger hit. Bigger box will produce lower notes (to a point). Is your Integra a hatchback? If so then you don't have to worry about taking up too much trunk room with the box. (if you fill half your trunk with a sealed box, it can start to behave like a bandpass enclosure, albeit without a tuned port). Also, use stuffing to get deeper/better response out of a sealed enclosure (unless specs say no). For the size, unless you're a whiz, you'll have to take your best guess. I would stay away from the extremes of the range, or if you get a specific volume then be within .1 cubic feet. Also, remember that the sub takes up some of the volume, so pay attention whether the volume spec includes the subwoofer. You should use 3/4" MDF for the box (minimum), so when figuring dimensions, subtract 1.5" from each side's external measurement to get the inside volume. Typically the width and height are determined by the car, then you calculate the volume to see how deep to make the box. Especially for a sub this badass, put each in it's own chamber, if not its own box. This means if it's in one box, there should be a panel in the middle dividing it into two halves. Seal all your seams/corners with silicone caulk or liquid nails. Use wood glue and small nails along all joints. The wood glue will be stronger than the nails once it's dry.

JL 13w7 & 1000/1 Settings


There is no "perfect" setting that can be placed in a manual. It's all done by ear. Your settings will vary depending on the vehicle you are in, the type of enclosure you have, the type of music you listen too, how much voltage your deck put's out. There are many variables, but I can try to give you a basic guide.

First of all you need to know your enclosure. If you have a ported enclosure tuned in the mid to low 30's you may want to set the low pass to around 70-80 hz with your sub sonic set at 30 hz. this will give you the higher bass frequency you need for the loud bass you want, and protect the sub from going too far below the tuned frequency of the enclosure, and losing it's composure.

As far as the gain, and bass boost are concerned, you just have to adjust them by ear. First adjust the radio volume to normal listening levels, by that I mean as loud as it can go without the speakers in the car sounding like ****. Now you adjust the gain first. slow turn the gain control, carefuly watching and listening to the sub.. Adjust the gain to the point of the woofer getting a lil sloppy then back it down a bit until the sound is clean again. Now do the same with the bass boost. if there is a bass boost frequency adjustment, set that as close to the tuned frequency of the box as you can.

If you are in a sealed box the adjustments are a bit easier, and are all about taste. Adjust the radio as described before, and put on your favorite song. Next start udjust thing lowpass frequency to taste, not too high tho, try not us higher than 100 hz in your sub's for better sound. Sub sonic is not quite as important in a sealed box, as there is much less danger of the sub losing control.

Well good luck, and hope this helps!

I have a 12W7 jl sub with no enclosure or amp.


Hello cdoran93,

Well, "best" and "loudest" are mutually exclusive. You can configure for one or the other, but not both at the same time.

The best (most accurate) bass is produced from a sealed enclosure, while the loudest (highest spl) is produced from a properly tuned ported enclosure. The recommended sealed box volume is 1.375 Cu.Ft. Ported is 1.75 Cu.Ft. For a ported enclosure, you need to decide what frequency to tune it for and then look at the JL specifications to the size of the port.

www.crutchfield.com has both types of enclosures at prices starting around $70.

Hope this helps.

8 inch woofer blown need specs...OHM, Impedence and wattage


John,
Checkout JL Audio's 8" subs I'll leave specs at the bottom, if you want to look around for something cheaper check out this install I did on a Jaguar X-Type. The sub here is a good example of a free air application and you can look for a sub with the same features. Keep in mind however this setup is using a high power Coustic 10" sub and you only need to handle the stock amp- 25 watts. So you may not need such a beefy sub, but something close would be good. If your sub uses a small enclosure go with something like the JL listed below. Good luck and let me know if you need anything else.7a2e6d4.jpg -Dynami

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.

They need 1.4-1.7 cubic ft per sub(ported box) less if it is sealed but I wouldn't recommend that, it sounds like ****. Google "Re audio box calculator" and use it to adjust your dementions to your application
