I bought this amp and man when it was working; it was the best amp i ever owned. this past week it started cutting in an out. i looked at the amp and the green power light was cutting in and out. i figured with the bass the wires might be coming loose. i un hooked all the wires and reconnected them. it seemed to work, but then started to repeat and when it did; this would become a regular problem... what should i do, i hate factory sound.

Re: j/l 500/1 amp
I'd lay you odds that you are driving the wrong speaker impedence and that you may have damaged the amp. This is most often true when you improperly bridge into the wrong load. If you are lucky enough to not have damaged the unit then you need to get your speaker load right at once before you fry it, if you do indeed have the wrong speaker load (too much).

Listen everyone who is having any JL 500/1 or 1000/1 amps. There are many reasons why your amps have failed. Most of the problem is the power supply mosfets shorted out and output mosfets shorted too. Those are the 2 biggest problems when you run these amps hard. Also the main power supply capacitors and the gate resistors mostly burn out when a power supply mosfet shorts. Some people if they remove the back cover may see signs of of the problem area and others will not. I have been repairing these paticular amps at least 2 to 3 a week with other amps I get in. It seems that the older ones people bought working are now failing. So this is just a quick overview of what your problem is and is part or is the problem guaranteed. Sometimes I get tired of seeing them coming in but it's what I do and know exactly where to start. I don't know at this time but I think for $160 if you send your JL 500/1 to JL they will just replace the board. Don't quote me on that cause prices change. I would call and ask. My repair depending on the damage is around $80-90 to repair these 500/1. The 1000/1 can be the same or higher. I can't tell you if I don't have it in front of me diagnosing it. As I said though, the problems are basicly the same for the most part and the amp will have to be repaired. I help people also who are electronicaly inclined and if they feel confident and can unsolder and solder and know thier way around a volt ohm digital meter I can walk them through the steps. It's not that hard everybody, really it is'nt. A little confidence and soldering and reading a volt meter and you can repair your own amp. Contact me if you need any help. Thank you!
This happens to me all the time during the warm months. The problem is likely that the amplifier is overheating because of location. If not properly ventilated, the amplifier will shut off before damage occurs. Is it located under a seat or other area where sufficient air flow is lacking? I solved this problem by moving my amplifier from under a seat to the trunk area.
Actually you answered your own question in your paragraph. I draw your attention to your statement of: "It will work for as long as I'm driving I will park my car, and when I
turn it back on every thing will be working just fine and, then a
couple minutes later, amp cuts out and won't hit for a couple hours or
a couple days.... I have checked the sub multiple times and I don't see
it being the sub or the amp"
You are correct it is neither the Sub nor the Amp. The problem is either your voltage regulator or your alternator. one and or the other is going bad.
Here is some advice check your ground wires, the buy a dual alternator kit, it contains the parts you will need to add an additional alternator to your car. This will provide the power you need.
Check the wires for a lose connection or corrosion. You may need a capacitor.
Basically, at low power the amplifier
is not asking for a lot of power from the electrical system to power
your sub woofer. For lack of a better term and probably the best way to
explain it is. It uses up all the power in the wires leading to it at a
high volume, and has to wait for more. Kind of like when someone squeezes a garden hose
when your trying to use it. That would be the high volume, starving the
amplifier. The capacitor stores power in it to power the amp at high
volume. 2 farads would probably be bulletproof on a single amplifier
system, but 1 farad should work well enough. Or seek help from an
expert on exactly what size capacitor you should use. If you find
yourself saying: My amp cuts out.
