Amp was working fine. i disconnected the sub for a while and the amp would turn on and then protection light started blinking and now wont run a sub. is there a way of reseting the amp? what causes the amp to go to protection mode when the sub is disconnected?

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Using an ohm meter to the sub will confirm whether its bad or not. Invest in a cheap test set of 6.5" speakers.
.A thumbs up would be greatly appreciated if this answer is helpful to you.
might have roasted your speakers voice coils a little which may be sending the amp into protect mode throw a speaker on it that you know works and if it doesnt trigger the protect circuit then you probably have a blown or almost sub.
are u sure u have them running at the right ohms, for not only the subs but the amp too...if you go lower than your amp is rated you can fry stuff...via protect mode......hopefully this helps
Overload maybe. If the amp is run at an improper impedence, the amp will shut down. If you are "CLIPPING" speakers / subwoofers the light will blink to indicate a hard clip . Example: 4ohm/2ohm stable amp with 4 ohm subs wired at 1 ohm.
It appears that the amp is going into protect mode. To eliminate external causes, read through the following page. Let me know if you have any other questions.
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!
In virtually all instances where the protection light is illuminated, the amplifier has gone into protection because the output transistors are shorted. To eliminate external wiring problems do the following.
Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still goes into protect, the amp likely has blown output transistors.
If it does have blown outputs, it's is likely due to the speaker wires shorting together when the woofer was out of the vehicle.
