amp on, no sound

[borntorun 10+ year member]

i know, this is another one of those threads, but searching turned up no solution.

we have a phoenix gold sub wired to 2ohms on a power acoustik amp. everything has been going great for a few months now, but tonight we had a problem.

first of all, the amp does not have a protection light...so im kind of in the dark as to if it is shutting down, or not.

loading/unloading things into the back of the vehicle the amp was bumped while the vehicle was off. turned the vehicle on, and the sub was on for a second, then cut out. the blue neon light on the amp is on, but there is no sound. there is sound coming from the headunit to the door speakers, but nothing coming from the subwoofer amp. the connections are good, it does have ground, 12v, and remote, because disconnecting any of these results in the amp light turning completely off. the fuses are also good. i have disconnected and reconnected all of the wiring from the amp, and from the sub. i didnt try a different ground location, because i dont think this is the problem (again, the light does come on), and i havent touched any connections in the back of the headunit because i know it has to be somewhere around the amp.

seems like the amp is grounding out somewhere and going into protection mode...doesnt it?

Have you checked you connection to the inside of the subwoofer box?

ohm out the sub and see if you get a reading, if you dont then something is wrong with the sub, maybe just connections but maybe worse. if you get nothing and all the wires are connected, then turn everything on and while the music is playing push in on the sub. if you get a buzzing sound then the sub is blown.

Check the fuse under the hood it might be blown. Remote wire alone can turn on the power light on the amp. Good luck to ya.

sounds like a blown sub or fuse to me. start there and then work your way up. also push the sub like the other guy said. those are the quickest ways to check without tearing stuff up
