My SH**TY first system is composed of a Visionik 12" Sub in a sealed box, with a 3 or 5 hundred watt amp. Im not sure. But my problem is that about a week ago, I flipped my sub to face up so that it wouldn't be bouncing off of the back of my seat, and since my amp has gone into protect mode. I flipped it back over, checked all the mires, fuses, EVERYTHING. the sub is good and all. I cannot figure out why it keeps going into protect mode. If i take the wires out of the back of the sub and put them back in it will turn green, but as soon as i play music the sub with hit for about 1 second before the amp shuts off and turns back to protect mode. PLEASSEEE HELP.
