Jl Audio 10W6v2 Car Subwoofer - Answered Questions & Fixed issues

Try this....the speaker that is not working, gently work the cone up and down with you fingers. Be careful not to go right thru the cone. One hand underneath(near webbing) and one hand on top over the dust cover. If you hear any kind of scratching, or noise, or it's not "breathing" freely, then the voice coil of that speaker may have overheated, or the speaker has extended above and beyond its range of movement (called excursion). And may as well be blown/dead/fried..however you want to say. I hope this is not the case for you.

If they are single voice coil speakers (1 positive and 1 negative terminal on each speaker) then connect from amps' Positive output terminal to spkr. 1 positive terminal, THEN spkr. 1 neg. terminal to spkr. 2 positive terminal, THEN spkr. 2 negative terminal to spkr. 3 positive terminal, THEN spkr. 3 negative terminal to amps' negative output terminal.

That is 3 speakers wired in series. if each spkr is 2ohms, then you will have a total 6 ohm load. If 4 ohm spkrs., then a total 12 ohm load, if 8 ohm spkr., then a total 24 ohm load.

Be careful because amps do not like these odd ohm load totals. You might get away with a 6 ohm total load. Depends on the amp.

Hello ama1228a,

You did not say what type of vehicle the box is to be mounted into. Many times, where the box goes dictates the shape and size you have to work with.

That JL W6 will work OK in a sealed box with as little as .625 CuFt of volume and a ported box with .75 CuFt, so you have lots of choices.

Here's a link to the PartsExpress box page. These are Goldwood boxes, so don't let the prices scare you away. They really are built well, and one of them will make your JL sound good.

Hope this helps.

Specs say it depends on the impedance of the speakers. https://www.jlaudio.com/products/jd250-1-car-audio-amplifiers-98360 https://www.google.com/search?q=jl+250%2F1+amp.+Wiring+diagram ..

sounds like the amps not rated for the resistance tha subs have it running at....are they a dual 2 or dual 4 ohm?is the amp rated for 1ohm? sounds like amps going into protect mode

Sounds like you either shorted something out or overloaded the amp. Is there any odor coming from it? If so It will need to be repaired or replaced. What did you have connected to it and how was it wired?

You will need to open it up to see if anything damaged. That does not look good at all from the outside.

In your world, what does best results mean to you. how are the hifonics mounted? open air, closed box, vented box (optimized to what freq)? trunk or inside vehicle? all these variations weigh heavily on your configuration. As does what 'best results" means to you.

Check your ground to make sure it is properly grounded

Disconnect all the speakers one at a time and see if it stops doing that, if it does you have a shorted speaker or wiring

Amps that big are usually fused on the feed wire, under the hood of the car, near the battery.

Re tune your amp

Check your speakers wiring to make sure they are not touching. This will make your amp go in protection mode.

Here's the Datasheet on the TDA7297 IC: http://pdf1.alldatasheet.com/datasheet-pdf/view/25110/STMICROELECTRONICS/TDA7297.html This should work for you. It also shows a recommended circuit for the part.

JL Audio JX1000, XD600/1, HD750/1 would all work nicely with those.

Make sure all your connections are tight , really tight . Check ground , make sure it's to clean shiney metal. Three subs are going to have a low ohm load if paralleled . These amps are not 1 ohm stable ,if below 1.5 ohm's you will have problems. They need to be series paralleled to raise the ohm load. These amps put out the same power from 4 to 1.5 ohms.

Parallel , all positives together , all negatives together . With 4 ,4ohm voice coils in parallel you get around 1 ohm .

Fried the outputs

they are most likely stretched out. try messing with the equalizer to make the sound more crisp.
