Shorted Out a JL Audio E4300 Amp

While re-installing the speaker wires in my vehicle I shortage out my JL Audio E4300 amp and now the protection light is on and won't go off. I accidently ran a screw through the middle of one of my speaker wires and when I turned up the music the E4300 cut off and I can't get the protection light to go off. I have completely removed all wires and then only plugged up power and ground - still no luck. Is the amp fried? Can I fix it in any way?

The screw through the speaker wire caused a dead short and turninged it up loud, you may have fried the capacitors on the output side of the amp circuit. It is easy to tell if you open the amp up, but do so with it disconnected and out of the car. The tops of the caps may be split or bulged. It is worth fixing in my opinion.

Amp comes on then shuts down JL 500/1


what do you have hooked up to it? Subs, Speaker, so on. it sounds like it is going into protection because of improper wiring... or it was improperly wired. if it is malfunctioning you need to take it to an authorized JL audio dealer. It's going to cost some cash unless you have a warranty on it and it was installed by a liscensed technician.

Xplod XM-554ZR Car Audio Amplifier: powr/protect light comes on red not green...


Hi, disconnect all speakers from unit and try again - if red light still shows then your amp has died.
If the light goes green, then start testing for shorted speaker/wiring. This includes speaker wiring to vehicle shorts - there should be an o/c reading on your meter

When i turn on the key the protect light comes on and it makes a funny sound


Something is shorted most likely. Check the wiring to your speakers. Check especially for stray strands of wire where the speaker wire connects at the amp and speakers.

Jl audio 250/1 thermal light


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.

Problem with amp...


In virtually all instances where the protection light is illuminated, the amplifier has gone into protection because the output transistors are shorted. To eliminate external wiring problems do the following.

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still goes into protect, the amp likely has blown output transistors.

If it does have blown outputs, it's is likely due to the speaker wires shorting together when the woofer was out of the vehicle.

JL 500/1


It sounds like you have a broken output filter inductor in the amplifier. You should be aware that the speaker outputs of the amp are biased at ~40v DC and can give a good shock if you touch the speaker wire while you're grounded (touching the body of the vehicle).

 

When you connected the speaker as you did, I would have expected the speaker to move in or out and remain there while the wire was connected to the housing of the amp. I'll assume that the amp was screwed down to the chassis of the vehicle. If it wasn't, you may have more than one problem.
