Why is there no sound from my subwoofer?
I have a boss amp. I have a Rockford fosgate sub. I recently moved my amp to a different location. Unplugged the battery and everything, have a good ground, remote, and power. Rca seem fine and worked earlier today. Speaker is fine and speaker wires are fine.
I put rca extensions and cut the remote wire and added wire to make them both longer to fit where I wanted.
I regrounded the amp and the power wire and speaker wires are the same.
The amp did not touch metal it was being mounted on carpet inside a compartment in my trunk, I have a mk4 jetta and it was going where the 6 disk cd changer was located.
This shows no signs of not working!
When I turn the car on the amp is getting power and the green light turns on fine.
No sound to subwoofer. Tried a friends speaker and no sound to that either.
Is the issue with my amp? Did moving it kill it? Are my rca on the amp or head unit broken? Did I fry it?

If you failed to disconnect the battery on your vehicle, or didn't remove the inline fuse that's supposed to be on the power wire near the battery, you may have inadvertently caused a spark to ground when removing / reattaching wires. A quick blast of full amperage battery power is sometimes enough to fry an amp before the fuse can blow. NEVER ever move live wires. Hopefully that didn't happen and you made a bad splice in the RCA cable instead. Splices are a bad idea with crimp connectors. Always solder them for trouble-free operation.
