Amplifeir keeps turning off

I have a jl slash series amp that keeps turning off when the amp is turned up. And when you turn it down the amp will sometimes kick in and be real loud but only sometimes when the main volume is down.

Re: amplifeir keeps turning off

HI K-****, Adjust your Gain setting to limit just enough so the amp does not go into Protect mode.

  1. Turn your Gain all the way down,
  2. then crank up the bass from your system.
  3. GRadually turn up the gain until you trip on protect.
  4. Turn the gain back a notch and your set for no more protect.

Have a jl audio 500/1 the red light blinks and no other light turns on. whats the problem with it?

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 audio 500 1 slash series the amp would cut on and off every now and then and when it is off i check to make sure power is getting to it and it is getting the full 12volts what could be the...

I had this same issue when I moved the Amp from one car to another.

I did not use the required 4 AWG wire for the Power connection. In my original car I had.

Replaced it and with the correct AWG and it the problem went away.

So check the Gauge wire your using. I tried to be cheap and it was a pain.

Have a JL audio slash 500 that isnt putting out any audio... i know the sub is fine. but i noticed the RCA inputs are loose and dont hold the cables very tight.. is this my problem and what can i do to...

Yes it possible that the inputs have been damaged on the circuit board of the amp. If the amp has hi level inputs you could try running a speaker wire input to it and see if it works. You might try another pair of rca cables to.

I have a jl audio slash 500/1 series amp, and it keeps blowing the fuse. am i using the right one? which one should i be using?

if its the fuse in the fuse link then you should be using the a 50A fuse thats if on your amp there is fuses that total 60A when you add it up and if it still blows then you might have a short in the power wire between the battery and the 50A fuse

My amp only powers on it gives no power to my subwoofers

1st check to see if the RCA's are plugged in if they are make sure the speakers are plugged in. Check at the amp and at the sub Alson check the input voltage switch. JL Audio Slash series amps have a high/low switch for your input voltage. And the last thing I can think of is if your using a remote wire to turn the amp in make sure the signal sensing switch is off. If your not using a remote wire turn it on....Hope this helps

your subwoofer is wired incorrectly to your amplifier. Figure out which ohm load of subs you have and then what ohm load options your amp is stable at. Next go to either the Crutchfield website. find their learning center. go to subwoofer wiring diagrams. or go to and find their section on it

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.
