Amp overheats & goes into protect even when turned down

Well, I may have spoke too soon. It's been over a month now, and I've not had the amp go into protect once, until today.

I decided earlier to redo the port on my box to tune a little higher. The amp is mounted to the side of the box. I just disconnected the remote gain, and rca's, then pulled the box out a bit and tipped it up to get to the screws on the underside.

Got the port done and went for a ride. The amp is back to going into protect constantly. I've changed the rca's and it still did it. Tried letting it sit powered on with the remote gain, rca's, and sub disconnected and after a few minutes, into protect it went.

It's also going into protect when the truck is started. Even if I turn the truck off while the amp is working, and start it right back up, the amp will be in protect for a minute before working.

I thought that maybe I loosened up a connection when I tipped the box up, but everything seems OK. The only write that was disturbed was the remote wire, and I fixed that before going for the drive.

Mounting amps to the box is hard on them. Probably a bad connection inside the amp.

Would that cause it to do this, but then work fine for awhile? This is the exact thing that it was doing a month or so ago. After I ran a ground to the frame is been working flawlessly till I tipped the box on it's back and ended up putting pressure on the wires.

An intermittent connection inside the amp can do this.

Pulled it out again to have a quick look. No smell, and nothing burnt. Only Thing I could visually see is that one of the 2 bifilar coils no longer has the glue keeping it from being able to wiggle back and forth. I can see how this could easily rub off the coating and cause a short. Could this possibly be the problem?

It could be anything. Everything is suspect. Without a good working knowledge of the amplifiers workings, there is a slim chance of fixing it unless something was obviously broken. Best bet would be to replace the amp, or send it to amp medics or some place to have it repaired.

Yeah, I'll probably end up sending it out. it's overheating again, same as before. Just weird that I upgrade the ground, and have been able to push the hell out of it for a month now with no issues. Move the box and disturb the wiring, note back to overheating again. Gonna see if a friend of mine has some spare time and hook it up in his truck. If it does it in there to it'll be sent out.

Yeah,I pulled the ground and checked the lug and it seemed fine. Checked under the hood to. Have a ground from the neg batt terminal to the alternative bracket, then another from the alt bracket to the frame. Both looked ok there too. Very irritating.
