They might be using the light to show other problems as well. Or the unit you bought has the same issue??

Double check all your connections, leave it unplugged for 24 hours after hitting the power button several times to drain the capacitors to hopefully clear any codes in the modual.

SOURCE: jl audio 250/1 thermal light

i was having issues with this amp as well, the thermal light was flashing every couple seconds. i checked all the connections and i discovered that when i pulled the power wire out the thermal light was still flashing, which tells me that there was no power from the power wire, but it was getting power from the remote wire. i know this because it would stop flashing when i removed the remote wire. but wouldnt start when i didnt connect the remote wire but connected the power wire. so with the power meter i checked the fuse and it was a little loose so i screwed it back in and the amp turned right on. 
to make a long story short, a flashing thermal light is a power supply issue.

It could be a number of things? 1 to many subs, speakers wired to the amp causing it to overheat and making the thermal light come on. 2 It all depends were your amp is. If it's clear and nothing covering it, obstructing it, Ie sub in front of it, amp inbetween the rear seats and sub.

I think you might have your remote turn on from your deck to amp hooked up wrong check that out!! I not are you familliar with the mr. butterworth crossover JL developed for that series of amp? Just like its big nrother the 1000x1 class D the built in smart crossover has many built in pretect modes. If your subs are drawing to much power it shuts down if they draw to little of ohms or to many but that 500 is 1 ohm stable so download the crossover settings from JL and go from there

I have a jl 500/1 amp hooked up in my car and the power light comes on for about 5 seconds then turns off. no sound out of the subs. it is hooked up to a factory deck through a high to low level converter....


hook up the remote wire ( or make sure its hooked up good) check your ground! ground wire not big enough awg wire and put on bare metal not more than 1 foot away from amp. bad ground will cause this.

Re-check all the connections to the speakers, The uPC monitors all the outputs and if any are taking more power than they should, the uPC shuts the amp down to protect the internal components. Don`t use tape joints alone, try to run the cable the full length without any joints. If you do have to piece the wires together, solder them and stagger the connections, in other words, make one lead shorter than the other so that if the tape does come off, the offending connection is well away from the other so they can never meet or connect to each other.

Disconnect all speaker wires from the amp and disconnect the RCA cables from the amp. If it still goes into protect mode, use a multimeter to confirm that you have 12v on the B+ and remote terminals. Place the black meter probe on the ground terminal of the amp when measuring the voltage. If the voltage is sufficient and the amp goes into protect, it will have to be repaired. JL only accepts repairs from authorized dealers. You'll have to find one in your area or you'll have to find a repair shop willing to work on JL amps.

Let me know if you have any other questions.
