If the low impedance light is coming on, you may have shorted wiring or a defective speaker. Disconnect all of the speaker wires from the amp. If the light does not come on, reconnect one speaker at a time to see if you can find the one causing the problem. If the first one you connect causes the problem try a second one. If the light comes on with no speakers connected to the amplifier, the amplifier is in need of repair.

JL Audio 1000/1 v2 distortion problem


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.

The low ohm light is amber... I have no noises coming out, when turning on the remote switch the low ohm light comes on a second before the power light comes on. I've used 8 gauge speaker and small small...


This means your subwoofer is not wired properly.
Remove the subwoofer wiring, and power on the system.
It is protecting itself from damage (if not already damaged).

When i turn the volume up my jl 1000/1 amp turns off then turns back on when the volume is low what can i do to fix this?


2 things, either your pushing too much power into the imputs (if using high inputs) and clipping the signal, or your running the ohms too low (lower then the amp can handle safely) by running multiple speakers of too low an ohm each. For example if your amp is 4 ohm stable and your running 2 4 ohm speakers in parallel that makes 2ohms and the amp can't handle a load that low. You can consult your manual and it will give you illistrations of wiring and ohm loads

How can i make my jl audio 12w3-d6 into a 4 ohms


it depends if the amp is mono or stereo and if it is bridged. if it is bridged the amp cant handle the speaker the best way is to lower the level on the amp or connect it to only one channel. also you might want to check your ground cable use a thick one and make sure its making good contact with the chassis. this happened to me. luck

Jl audio 300/4 low ohms light wont go off


If the low ohms light is on then you have your speakers wired to low. I need to know some more info like what type of speakers you have running on this amp and how many. Also was it working before and then it started doing this? Check the ohms with a volt meter if you know how, if not just get a volt/ohm meter and set it to the ohms setting and then take the positive(red probe) and touch it to the positive terminal on the speaker and then the negative(black probe) to the negative terminal and see what it reads. Make sure you check how low in ohms your amp is capable of handling. If you don't know just google the model of your amp and you will find a site that has a manual or just go to JL audios web site and you should find out there with no problem. Let me know what you find so I can assist you more if need be cause I also repair amplifires for a living and have many years experienc and I'm the cheapest amp repair business you will find any where. Good luck

500/1- Low ohm light


Disconnect the speaker wires from the amplifier's terminal block. If the low ohm light still comes on with no speaker wires connected, the amplifier will need to be repaired.

If the light no longer comes on, check the speakers and the wiring.

Car Sub JL 12w3 low sound


So I am assuming that you have just setup/wired this up recently? Have you had this working before?
You can have a look at the gain control on the amp & see if this have been set really low. This will help if the signal coming from your stereo is weak. The other thing I would suggest is to make sure that the amp can actually push this sub. I know what the specs say:

  • 1 channel audio amplifier
  • 1 x 350W RMS @ 1.0% THD
  • ThermalThrote full-on power assurance
  • 2 ohms stable (non-bridged mode only)
  • RCA type inputs
  • 0.3-6.0 VRMS input capability
  • Continuously variable High-Pass & Low Pass 50-250 Hz
  • Continuously variable Bass Boost settings (0 tp +12dB)
  • Frequency responce: 10-30,000 Hz
  • S/N >104 dBA at full power @ 0.1% THD
  • >80 dBA at 1W/1M
  • Remote gain control, mounting hardware & screws included
but I don't believe most of these. Many manufacturers embellish what their products can actually do! With the bigger more established brands such as JL Audio you will have no problems, their products have been tried & tested so much on the competition circuit.
