    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.

For the record, I've never seen an Olympus /anything/ at World Finals. Be wary of any product that claims 'competition,' especially if it looks fancy.


Loud is often ugly. Like fast.


If you're going to buy new equipment (or used, for that matter) look into the more popular internet direct brands;

Plenty of people on the forums will be happy to contribute to your success in mobile audio - if for competition or just for personal use.

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 cant get my jl audio w6 10s to give off much bass with the jl audio 500/1 amp


here is a manual for your subwoofers: http://mobile.jlaudio.com/pdfs/8-12W6_BDS.pdf

use the wiring diagram for 1.5? (1.5ohm) with 2 speakers. the diagram for 3 speakers will not work, because it would bring the load down to 1 ohm, and the amp cannot go below 1.5 ohm.

to set up the amp:

under "preamp output section", on the "output mode" switch, select "amp filter"

to set up the levels: start with the amp gain pretty far down- with the input voltage on low for line level outputs from the deck, and on high for speaker outputs from the deck. now turn your cd deck as far up as it will go until it distorts, then turn the cd deck down to just where it stops distorting. now, you can start to turn up the gain on the amp.

on the filters, youll prolly want the cutoff filter around 100hz @ 24db slope. start with the infrasonic filters off, but, if you do get into them, try centering between 30 and 60hz on either, and, possibly dropping the cutoff filter to 80hz.

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.

Problem when hooking two 12 inch subs to one amp


the amp is no where near strong enough that sound you hear is called hard clipping and it will destroy your subs in minutes. depending on what model JL subs you have I can sell you a better amp.
