Jl Audio 500/1 Car Audio

We have all the wires hooked up right.... I even tested the wires with another amp and that amp worked. I was just wondering if their are any fuses in the jl audio that might have blown or any other signs I should look for... why my JL audio would not be working?

There are no fuses inside the amp.

Are any of the lights lighting up on the amp?

If so, which ones?

    How much DC voltage do you have across the positive and negative speaker terminals (black meter probe on the negative speaker terminal, red meter probe on the positive speaker terminal)?

    How much DC voltage do you have from the chassis ground terminal to the positive speaker terminal (black meter probe on the chassis ground terminal, red meter probe on the positive speaker terminal)?

    How much DC voltage do you have from the chassis ground terminal to the negative speaker terminal (black meter probe on the chassis ground terminal, red meter probe on the negative speaker terminal)?

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.

Can you run a 8 gauge power wire to a jl audio 1000/1 amp and not have problems even though jl reccommends 4 gauge power wire?


Hi, if you're going to run a smaller wire, you also need to use a smaller fuse. A 50 amp fuse is needed for 8 gage wire. The fuse is there to keep the wire insulation from melting, which is what will happen if you run too much power thru the wire. If you don't plan to turn the amp up too high, this may work fine, but I would test it first with a 50 amp fuse before installing. You will need all of the speakers hooked up and the gain set to max to test the power draw. See the following link on wire sizing for more info: http://www.bcae1.com/wire.htm

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.

Installin car systems


you dont want to connect both of those amplifiers together. You could run them separately to separate subs or the jl to your sub and your alpine to your front speakers. But you dont ever want to mix and match amps to the same sub. Even if you had 2 jl500/1's you wouldnt want to just hook them up together. Because they both have to be putting out the exact same amount of power. Which no 2 amps are ever exactly the same. Some companies make bridges to properly connect 2 exact amps together. I Hooked up 2 JL 1000/1's to each voice coil on a 13.5 W7 and i smoked the sub. So i definitely dont reccommend doing it unless the amps are conneccted to separate things.

Sounds like you fried the channel on the amp or your gain might be up to high for the speaker

I bought a 500/1 jl audio amp and also a w7 10 sub


if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...

Low ohm light on my jl 500/1


If the low impedance light is on, the amp probably has shorted output transistors. If you don't know of a good local repair shop, call 'several' of the local audio sales/installation shops to see who they use. If more than one audio shop recommends the same repair shop, they probably do good work.

My JL subs just dont beat like the ONES IVE HAD before as well as the ones my friends have had


sounds like they have your sub amp in mono but they put the speakers in series which totally cancels the benefit of running your amp in mono. you will probably be happier if you just hook the left speaker to left plus and minus and the right to right plus and minus. Cuz even though subs aren't directional they do pass some higher frequencies that are and that dilutes the stereo effect.
