You have to go through an authorized dealer to get service from JL. Most good repair shops can repair most problems with them.

Before you send it off, confirm that you have good DC voltage at the remote and B+ terminals.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

I have a Kenwood KNR-D558BT with JL amp and speakers, I went to turn it on and lights come on but can't get any sound


You have to isolate the source of the problem..If you have another known good amp throw that in there to see what happens. If no sound also then your head (Kenwood) unit if fubar. If it works then it is your JL amp. Chances are your speakers are good unless you smoked them to death by over driving.!!!!

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.

JL Amp isn't powering subs and speakers


silly as it sounds, you may want to check your EQ settings on your headunit. Things like sub volume, SLA, loudness and balance. When they replaced your battery, those old settings were lost.

Trouble with jl amp


well start with. turn your hi pass completely off. Turn your bass boost completely off. Turn your input gain copletely down. and turn your cd player to about 3/4 of what you listen to it at. Then turn your input up until it starts to sound a little dirty(distortion) then turn it down a notch. set it at a 80 herz filter so it allows nothing over 80 herz to come through. I just installed one of these jl amps a week ago. 1400.1 and it made two kicker cvt's sound amazing just have to set it just exactly like i told you. it will hit tight as hell and loud and it will hit all frequencies way better.

Jl audio 250/1 amp


This could be due to multiple things. First I would run a test light to the speaker leads of the amp as if you were running your speaker...it should light up and blink to the sound of music coming through. If no sound then most likely your RCA cables are bad or input jackets on the amp are loose and be shorting out causing the low light to come on. If you know 100 percent that you bought that amp in good running condition then most likely its something simple like the RCA wires are bad..Hope this kind of helps you out.

Scratchy single channel on amp


I had the same amp! It is the JL 300/4 and one of the chanels came in really fuzzy. It sounded as if the the wires were touching during my installation. I called JL and a JL authorized dealer it would have costed me 190 dollars total to get the amp fixed. Instead I opened up the amp to see if anything looked out of the ordinary. When you open the amp, see if the green fuse looking things are aligned. If they are not aligned then straighten them out. I think they had gotten out of place from being dropped becaue I baught my amp used. My amp works perfectly now!

This is no joke man, I did this just yesterday and was really excited to save 190 bucks. I'm not a technical guy or anything all I know is the green things are located behind the out puts inside the amp.

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.
