All of a sudden my subs started working and i did not get to check it out until the next morning, i replaced both fuses in the engine but the amp still did not work, as i was looking at it it turned on for 15 seconds then shut off i started checking all connections when inoticed the ground terminal was partially melted and the end of the ground wire was now black, the amp diagnostic light is on and goes of when i disconnect the negative input.

Re: sub amp not working anymore
Sounds like a typical case of poor conections causing the amp to fail... take the cover off of the amp. Inspect where the terminal blocks meet the circuit board. SOmetimes you can repair it sometimes its just too far fried..

Check your fuses on your amp power lead and amp or make sure your amp is turning on the should be a light somewhere amps can break more times then the sub. Check all your connections or check your amp and head unit settings most probably a fuse mine blow sometimes
okay , well you need to make sure all your conections are in the right spots, and that your IN LINE FUSE, between your amp and battery, the big glass one is not burnt, just take a look at the metal piece inside , if its a sold metal piece its good, if its burnt in half like a broken bridge it needs to be replaced. the next thing is the fuse on your amp, you need to make sure it is not burnt also. Check your remote that it is hooked up to the right wire. then check that your sub/speaker wires are connected properly and secure. YOUR GROUND WIRE IS HUGE HERE also. MAKE SURE IT IS GROUNDED TO A GOOD SPOT, YOU MAY HAVE TO MOVE IT AROUND A FEW TIMES TO FIND A GOOD GROUND!!!! if you check all of these things, it should work fine.. you can fiddle with your amp and bass settings levels. turn em up so when it works you know it, but not too much you dont wanna blow nothing :)
Your best bet is to buy a cap. A capacitor is an external battery booster like device. It boost power to amp. The thicker the wire the better. Power and ground. Shorter thicker ground wire the better. Make sure it is not on a painted surface. Scrape down to metal surface!!!!
although an odd thing to have happen it does sound like you blew your amp. check the fuses in it to see if you can avoid having to replace the amp and instead replace a few dollar fuse also check the fuses where you had this pluged in. hope this helps a little. if you give the amp type i may be able to help a little more
You did not say whether or not you checked the wiring going to your subs. Many times, a shorted or grounded speaker wire will cause an amp to fail. And if the amp powers up OK with the subs disconnected, I'd suspect one or more of the wires.
Sounds like a problem with the sound chip in the stereo. Disconnect the rca cables from the subs and check to see if the audio returns. If so. try using a different rca connection in the back. Also i think on them radio's if there is a built in sub drive you need to turn that off if you are using a amp to run the subs.
This sounds like a problem with the head unit output to the sub amp. Are you using a Pioneer head unit? If so, you may have a problem with some surface mounted fuses inside the radio on the main board. Certain Pioneer head units have a common problem with these fuses blowing. They are fuses for the ground on the RCA outputs.
Let me know if this is the case, and if it is I can give you the part number of these fuses and tell you where they are located, but you would need good soldering skills to replace them. Also let me know what model number your head unit is.
