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?

Re: Shorted Out a JL Audio E4300 Amp
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.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

1 make sure its hocked up properly .2 see i if the protection comes on.. with out the speaker wires hocked up if it does the u have a bad amp.3 if the amp protection light is off with out the speaker being hocked up and after hocking up the speaker it comes on the u have bad wiring to your speaker or a bad speaker
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.
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
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.
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.
hi, have you figured out whats wrong with ur amp ...i have the same amp ....and as soon as i finished the connections ...and connect the remote on wire,,, the amp goes on ...making a ticking sound with the green light blinking and the red light staying solid on ...whats the problem please help ....how can i fix this ......my amp is a jl e6450 ....im using a panasonic cd player with a built in amp ....and thats the cd player im trying to connect to the jl amp ...please HELP
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.
