Jl Audio Popular Questions, Answers, Tips & Manuals

Are you sure you getting enough power to push everything. I have seen when the voltage is too low coming in, the amps will shut down so they don't overheat. Once they've cooled off and the volume level is lowered they will kick in again. Low voltage and a heavy draw will create massive amounts of heat.

how do you have the speakers wired to the amp.

They should be wired in series (to arrive at 4ohms) and bridged at the amp.

This means your amp is in "protect mode" this light indicates that your amp is having a short circuit or loose of power.
Check your cables, if they are secured & no exposed wire And most important of all, check your voltage reading, it must be above 12v.
Loosing voltage in car audio is the number1 factor of heat/thermal problem & fire.
When an amp looses voltage, heat builds up inside it. Too much heat will make the amp be on "protect mode", excessive voltage drop will cause the amp's circuit board & other parts to be burned.
So, always watch your Voltage, either with a plug-in volt-meter or with a fuse holder & voltmeter.
Hope this helps.

Well to be honest the question and subject title is a bit vague. BUT! if your lights went out after installing the sub i would say check all your wiring from stereo to amp to speakers. If that isnt invloved and your lights have gone out start by checking your owners manual and looking up the fuse diagram for your vehicle. Check those fuses. The Fuse box in your vehicle is located to the left of the instrument cluster visible when the driver side door is open there is a cover with a latch turn the latch to open it. There may also be a possibility of it having a relay which would be located in the other fuse panel located under the hood of your behicle next to the air filter.

The most likely solution is that your voltage is dropping too much and the amp is going into protect mode to save itself because of the lack of power. Double check fuses in the amp first and then on the power cable and third make sure all the connections are solid, i.e. ground and power wire. Another thing might be to check that you didn't switch the polarity by connecting negative and positive wires to their opposites.

your magnet has shifted you would hsve to call jl audio for help 954-443-1100

its real simple. your under powered.

your W6s RMS at 500 watts EACH and your sending em 250RMS (half what they need)
The 'pop' your hearing is the failure to supply enough power to draw the cone back in time and collides with the next wave of sound.

prove it?
drive a single W6 with your 500/1 bridged.
i'll bet your pop goes away.

long term, get another 500/1 or jump up to a 1000/1v2.

I also HIGHLY recommend JL's in-line audio cleaner. If i recall it was like 60 bucks but waaaay worth it. makes sure that theres no distortion in the source input to your amp(s), which...keeps your subs from trying to reproduce transients and delivers only clear signal to your subs void of all clipping signals. Its an active electronic compoent.


PS: if you are pushing 12W6's, i had the same setup once...I had W3s connected to my 500/1 and upgraded to the W6s...had the same issue your describing, and then got the 1000/1. happy ending.

No, However, you should. Best conductor for your signal path. Brass screws aren't too terribly expensive and you can get them at ACE or Lowes hardware almost always.

Check the ground wire to the car make sure that you have bare metal and that the contact between the car and the wire is good. Ensure that the ground wire is in all the way. What size ground wire are you using. I would say don't use smaller than 4ga for a 1000 watt amps.
Also has the amp been screwed or velcroed to the box? Sometimes amp connections become loose from the vibrations of the bass. So it's possible it might be an internal issue or that the wire isn't in all the way.
I would suggest also taking the amp completely out of the car and inspecting the terminals to make sure they aren't loose or corroded.

Sounds like your remote wire is loose or bad. I would thoroughly check that out

If your sure the unit is getting the correct power, check the ground cable, make sure it is connected to a clean surface. (remove any paint where the ground is connected.) Double check your wiring. Make sure all of your connections are good. Do not forget the fuse holder, check it too.

The low voltage light would indicate that there is not enough power reaching the amplifier through the power wire. Are you using 4awg or bigger wire? Is the amp grounded well? Does this happen all the time or just at high volume?

Try checking your power and ground connections and ensure that you are using the correct size of wire.

Most likely a plugged gas tank vent valve. Located on top of gas tank.

It could be a number of things? 1 to many subs, speakers wired to the amp causing it to overheat and making the thermal light come on. 2 It all depends were your amp is. If it's clear and nothing covering it, obstructing it, Ie sub in front of it, amp inbetween the rear seats and sub.

check how secure your earth strap is for the amp, mabye try thicker cable, you can get interference suppressors as well which may help and are cheap.

please explain your configuration

The amp may no thav eenough to push these subs, these are top of the line subs, they probably require a bigger amp, if you are running other speakers through this also, you certainly need another amp, or a bigger one with more channels. also double check all your wiring.

I've had similar problems, usually for me it ends up being a bad ground.

Check the remote lead and see if it is getting power at the amp when it won't come on that way you know if the issue is with the head unit or the amplifier.

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
