Anyone had their 500/1 do this?

My friend has a 2003 Civic 4-door, and he is using 2 10w3v2 dual 4's, wired to 4 ohms in a box built to spec.

Everything is installed correctly; I oversaw the install myself. The amp is getting 14.4v when the car is on, and 12.6v when the car is off. He is using the high level input, and it is installed correctly. The amp's power and ground wires are 4awg, the ground is a foot long, and it goes straight to shiny metal. What I'm trying to say here, I have no doubt that it is installed correctly. I am very familiar with Civics and have a considerable knowledge of installing.

What happens is, he turns the radio on, the amp senses the signal, and turns on. It plays normally for ~3 seconds, and then the amp itself starts making a high-pitched whine, and the subs play static, very loud. The power light and the low ohm light turn on, and the amp continues to whine and play static, even after the car is turned off.

Anyone else had this experience? My friend Alex (marineeagle28 on here) had this problem with his, or I assume. He told me of similar signs.

have you contacted JL?

I hear they have good customer service, and I would also be interested in what is going on

and if its broken they will charge you the same if not more to fix it, then it would cost just to buy it new.

Oh, and I forgot to mention that it does it, even if the subs aren't connected.

Yes, JL has been contacted

Hi Jordan,
Those symptoms are indicative of a low impedance problem. Because the amp is exhibiting the problem with/without speakers attached indicates that there has been damage to the amp. The amplifier can be repaired, there's a flat rate of: $180.00, it will be brought back to original operating specifications and, will have a 90 day warranty. It needs to be sent in via any of our authorized dealers. You can find a dealer by following this link: http://mobile.jlaudio.com/dealerfind.php I would also check the woofers and, the wiring to the woofers while the amp is being taken care of to ensure that it won’t have the same problem again.

never heard of such a thing, and I have my 500/1 hooked up with low level inputs and my 1000/1 with the high level, both work perfectly.

i dunno man i got 500/1 v2 it works fine i use the low level inputs cuz on the high it goes way down,

hopefuly u bought urs from a shop and have a warranty

so ur saying the amp itself makes a noise?

Talk to DAAMPS.com ! . I got my JL 500/1 fixed by them for only $67. And they had to fix 8 output transistors(all of them) . Very good customer service !

Maybe you have a blown speaker and fried the amp? I have a soundstream 1000 and I toasted a speaker and did not realize it until it was too late.

think we found the problem

That part seems to have come loose during shipping. He bought it on eGay, and the douche put it in a big box, and wrapped it in the little bubble wrap once, so the amp was probably tumbling around for its whole journey.
