Question about Jl Audio 500/1 Car Audio Amplifier

1 Answer

No sound I have 500/1 running 2 12's, (8gauge power and ground wire). One day all of a sudden heard a boom followed by the subs putting out a huge constant noise. I disconnected it from the power and when i reconnected it it powers up but nothing else. No sound coming from the subs. Power light is on but the other two lights are off. Is there anything i can check myself that could be an easy fix or identification of the problem. i hadn't changed anything to do with the wiring or anything since i have had the amp so the problem was an unexpected surprise. I would love to keep this amp so any help would be much appreciated.

As u have speakers with u u connect another speaker in to the sub connection and reduce the volume to min and check if sound is coming use another wire to connect the speaker to the amp and if it is working u check the cable then the sub it would have burned off due to some internal problems and it has to be checked by a technician this problem may be due to wire broken or something like that

98 volvo s70 last week I was backing up heard a boom so i stopped backed up again heard a boom again so i put the car in park then put it in drive pressed on the gas car will not go start shaking and...

I\'m thinking out loud here - if the car won\'t move when you put it in gear, it sounds like maybe the torque converter is bad. If it\'s unbalanced, you\'d get vibrations and the car may not move.

Water under the car may or may not be related. Is that maybe just a few drops, like from the A/C condensation?

If it were the water pump, then the car wouldn\'t start/run because that belt also drives the cams (without which the car won\'t run at all).

1, Check the coolant level - is it normal or low? You can dip a finger in the water on the ground and touch it to your tongue. If it tastes nasty sweet, it\'s coolant (don\'t swallow, rinse your mouth well with water and spit it out).

2, Does the car start/idle normally? If so, then it\'s something with the transmission if the car doesn\'t move back/forth. It\'s a front wheel drive car, so maybe look at the drive shafts inside of the front wheel to see if there\'s oil/grease splattered and if anything looks broken.

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.

2 12" subs + 600W amp. Turn on, goes boom once, then red light

Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.

unfortunately that's going to be a labor intensive project. You will have to follow the wires to where they go and make sure that they are all tight.

Being that the sub stays on you know you are looking for a loose wire off the other amplifier or the head unit depending on how you are powering those speakers.

if you have two amps one for the subs and one for the mains its probably not the power or ground going to them since both are not shutting down but check where the power splits to each amp.

start at the amp that isn't working unhook the cables. Test that those cables have power and proper ground then make sure they go back on cleanly (no loose strands) and tightly. proceed to follow the power wires to where they are connected.and double check everything.

If you have access to a continuity and voltage tester that will make it a bit simpler.

Depending on how clean an install it is (no panels, speaker boxes amps or seats to remove) it shouldn't take more than an hour or so. I always recommend that connections to power blocks remain easily accessible as I have had to remove amps, subs and junk like neon to get at wiring and its always a nightmare.

hope that helps

Have a jl audio 500/1 i think something is wrong with the ground on the amp i intalled it and it was load sounded good but after a couple days i would turn it up and it would cut out until i turned it down...

you could have too small of wiring going to the amp for one.. you need to check the ohm load that you have the subs wired at to the amp... this is a HUGE reason for amps not putting out like they should... If it's low of an ohm load for the amp then the amp will act funny and shut off a lot... if you leave it like that it can fry the amp.

Subs dont work when base is up high

Sounds like the amps needing more current available to it-You should have 4 gauge power coming off the battery going into a distribution block from there a 4 gauge to a 1 farad capacitor off the block -4 gauge to the ground for the capacitor -and two + leads from the block to your amps-you would do well with 6 gauge there.- That is to ensure that you have plenty of power on tap when needed and not trying to draw it off your charging system on heavy current demands.Make sure that your grounds are well placed and solidly connected. As for putting 600+watts on a pair of 8z......i hope that they are the CVR or the L5 / L7 series to take that much power,I've seen it done and the ones i heard sounded badass(L7 series)-but that was at the stereo shop so they had they stuff on HITTN status up in there. If your running the "cvr" or the "comp" series you might be throwing too much power on them -might want to step up your subs to a set of 12s just to get more air moving in there- good luck

Subs stoped

Any sub can be blown in 30sec if given bad clipped power, so just measure them with a multimeter and see if the coils still have resistance. Throw away the test light and only use a multimeter.

Whenever i wire 2 4 ohm svc subs the system just starts to pound real hard and its not like bass moving to music but just bass just moving up and down

It sounds like you have an open shield ground. To check the shield in your head unit, read through the following page.

Sub is getting no sound

Sounds like you answered your own question when you said you were getting no sound from your deck to your sub.
