Question about Jl Audio 250/1 Car Audio Amplifier

1 Answer

Sealed subwoofer box with two 10" jl audio subs hooked up to jl audio 250/1

Everything works great but sometimes I get a funny noise like there are two signals going thru the amp. I hear the bass from the music but I can also hear something else. If I turn the volume down all the way I can still hear the funny noise at the same level. When I go to the back hatch area with the volume down all the way I see the subs going in and out and they make a noise like they are rubbing. I don't know how else to explain the noise but from the driver seat it almost sounds like the rear wiper is running that’s the kind of noise it makes it’s like some kind of interference. Thanks for the help

You mite have the gain to high turn it down a bit just because there's a max gain doesn't mean you need to use it . you mite have to turn the bass boost up. you should get a bit better sound out of it

One sub not working

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.

I hooked up my two 10 inch JL Audio W3v2 2 ohms to a mono JL Audio 500.1 amp and the subs will not work. I have the subs wired in a series. I then hooked them up to my friends amp and the subs worked. Any...

try one at a time. if they work then try hooking them up differently. if none work, then check to see that your amp is not in protect mode. if amp is ok, then check to make sure you have your rcas connected to your amp. in other words, re-check all your wiring. if still nothing, try your amp on your friends car and vise versa.

Jl 12w3v3 started smoking after hookup

Dang man you roasted it, take it in and get it replaced.Check the gain on the amp try it at 1/3 to 1/2 gain and dont crank up the bass boost all the way try it at like 2/3 that should clean up your sound and cut down distortion-distortion kills subs by heat.

your subwoofer is wired incorrectly to your amplifier. Figure out which ohm load of subs you have and then what ohm load options your amp is stable at. Next go to either the Crutchfield website. find their learning center. go to subwoofer wiring diagrams. or go to and find their section on it

I need to find a good sub box for my 10 inch JL w6

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.

Popping sound! please help - jl 500/1 and two jl w3v3 2ohm subs

no connection are good + to + -to - thats all that matters. either the speakers are blown or you need a stronger amp. since you already tried speakers probably need bigger amp. definitley not the box. no such thing as a break in period, are the subs 10 12 inch or what. you could try to bridge them too that means hook both up to the same +-terminals, 2 wires per screw. it usually isnt the way they hook them up, its the wires fuses etc that cause problems. what guage wires is the speaker wire, the power line etc. if you give me these guages i might be able to get somewere
