Jl audio 1000/1 low voltage -keeps shutting off at high volume

You should definitely upgrade the power wire to the sub amp to 4 gauge -absolutely your choking your amp its starving for current-poor thing is starving !!!!!!!

I looked up the correct way to wire my JL 13.5W7

1000/1v2 Class D Monoblock Subwoofer Amplifier Specifications:

Rated Power:
1000 W RMS @ 1.5 ohm - 4 ohm (11V-14.5V)

THD at Rated Power:
<0.05% @ 4 ohm

S/N Ratio:
>95dB below rated power (A-weighted, 20 Hz - 20 kHz noise bandwidth)

Frequency Response:
5 Hz - 250 Hz (+0, -1dB)

Damping Factor:
>500 @ 4 ohm / 50 Hz

According to the chart your amp is only stable down to 1.5 Ohms, so running at .75 Ohms the noise you are hearing is the amp clipping (running more power than it can handle at low ohms)
I would suggest wiring it in series, or you could adjust the gain on the amp until the popping goes away.

Hope this helps.

I bought a 500/1 jl audio amp and also a w7 10 sub

if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...

NO it won't be your battery. Sounds more like your deck.

My JL audio 1000 x 1 hooked up to 2. 15 Sundowns I play it and then after awhile it shuts down and says low voltage why is this happening

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

Amp goes into protection mode

Sounds like you are running your subs at to low of ohm. Amps are rated differently on the levels of ohms or resistance that they can get to. If you have a dual 4ohm sub and run it in pairrell it will drop to 2ohm and if you run the same sub in series it will be 8ohm. Your amp will go into protection if the ohm is to low.

I have a jl audio jx500-1d went on protection mode and already disconnect every cable to it and try it again but same thing goes to protection 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?

JL AUDIO JX 1000.1D protect light comes on some damage to rca's but no visual loose connections ...help

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

500/1 sub amp stopped working, burnt rubber smell

It sounds like the power supply failed. Generally when the supply fails in that amp, you have to replace all 8 of the power supply FETs and all 8 of the 47 ohm surface mount resistors. Many times, the supply fails because one or two of the output transistors have failed.

If you want to have JL repair it, you MUST go through an authorized JL dealer.

If you have a good local repair shop, they should be able to repair it.

Let me know if you have any other questions.

Jl 500/1 amp speakers thump when I hit bumps in the road

Definitely check to make sure your amp and speaker enclosure are securely mounted to your vehicle, also check all wiring connections- it sounds like something is loose or there's a short. Secure everything and triple check all connections & I believe all will be well. If you need further help please don't hesitate to ask!

Need resistors for JL 500/1

If you have the old ones that you are trying to replace, Radio shack has tons, as well as guides to show you how the bands are deciphered. Hope this helps

I have a jl audio jx 1000 .1 and I have two hifonics 12 both are 4 ohms subs how can I wire them to my amp for best results?

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.

My amp jl audio 500/1 i connect it and the green

Check the remote lead and see if it is getting power at the amp when it won't come on that way you know if the issue is with the head unit or the amplifier.
