Problem my amp light comes on but im not getting no sound from my subs, im just wondering is the amp blown and is there anyway i can fix it?

I did that after two copies of a Klipsch Subwoofer had the amp die. Disconnect the wires that run from the internal amp to the driver and connect the driver directly to your new amp but observe the impedance. If you have the ability to limit the high frequencies do so as they are wasted on a sub anyway.

You are right about the scratching sound meaning the speaker is blown. The other one by it not playing it could mean the voice coils in it are blown or burnt.The safest way to check the speaker is to connect it to a standard 9 volt battery and listen for a popping noise when you make the connection and look the see if the cone stands up as long as the connection is made n returns to normal and no noises when disconnected from the 9 volt battery. To test this while the sub is plugged in to the amp but out of the box move the cone as far in and as far out as it will go. If it comes on while u hold it on either one of these positions but when released it goes back to not playing then the coils in it are blown or burnt and is no longer any good. As for selling the box its on you, aim anywhere from 2/3 to 1/2 the price you paid for it minus the speakers.

it sounds like it could be a blown channel in the amp. if the sub was blown it would still work just sound horrible. i have blown many subs and amps. you can bring it to an audio shop near you and they can fix it. i just got one of my channels fixed for 35$

It's blown due to ohmload.

try pluging in a diff, speaker to the amp see if u get sound.try powering the sub with a home radio just to see if u get sound at all if ur getting sound from the sub then its the amp but u could of damaged it when the amp over heated

IVE HAD 2 JL 1000/1S DO THIS TO ME EACH TIME ITS TURNED OUT TO BE A SHORT IN THE RCA IMPUT BUT ALSO CHECK YOUR RCA CABLES AND THE SUB INPUT ON YOUR HEADUNIT

Check your speakers with an ohm meter. They should have some resistance but not totally shorted. Its prob the amp that got fried. Connect the amp to the battery with no speakers attached to it if the protection light still comes on then the amp is blown.

If the amp is blown you can send it to people on ebay and get it fixed pretty cheap. Good luck!

how did he messed up? anyways, if u push the cone of the sub down and u hear a sound like "TUN!" its most likely ur sub is irremediably damaged. The cone needs to come up perfectly as a good sub would do. I need to know exactly what ur friend did b.c it is quite weird to mess a good sub by slightly switching cables

make sure your speakers are connected correctly if subs and are inside the box then check connections also at times the rca at the back of the head unit can disconnect. if power light is on then error is either speakers not connected correctly, rca faulty or not connected or speaker output on amp is blown

you have a foulty amp i wtake it bk and change it
