what amp, what else is in the car, MORE INFO!!!

The speaker wires are shorted together, a speaker wire is shorted to ground, the power/ground are hooked up backwards, a speaker is blown, or the amp is in need of repair.

Hifonix BX1000d, the speaker as been sitting for 2 months, worked perfectly before this install, what do u mean by speaker wires are shorted together kross? speakers work also, i checked the ground, hooked to the body of the car by the driver's side foot panel by the door

Forgot to mention, another possible cause could be low voltage to the amp, which could be caused by either a bad power connection, or bad ground connection.

Anyway, try turning on the amp with everything else disconnected from it. Remove the input RCA's (make sure they don't accidently touch the power lines!), and unhook the speaker wires from the amp. Make sure you remove the speaker wires from the amp, as opposed to from the sub. Does it still go into protect and shut off? If so, it's either bad power, or a busted amp.

i unpluged the rcas and speaker wire, and still the same thing happens, maybe i will try switching out the fuse to 100amp

It's possible the fuse is bad. Also, can you check the voltage your amp is getting? Do you have a multimeter?

i have never seen a fuse go bad but still let power go to the amp.... //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif

i switched back to 100amp fuse but its still the same thing, any other suggestions?

looks like your amp is defected/or you damaged it hooking it up. same thing happen to me. idk if you disconnected batter or not and power wire sparked your power inpute can do something...hook up another amp and see if its the same problem occurs

i plugged the power wire last, will try to mount the ground wire somewhere else
