Okay, so I pulled the head unit and replaced the RCAs just as a precaution and checked everything from front to back and there are no cuts, breaks or loose connections in any of the wires. I hooked everything back up and noticed the power light on the amp would flicker off from time to time. The amp has a warning light on it; green=clipping, red=protect. When the power light starts flickering off the interior lights also flicker as if it's killing some major voltage. The warning light stays on green (clipping) the entire time it's on and the light changes to red (protect) when the lights start flickering. Pulled the cover off the amp and it doesn't smell burned at all. After hooking everything back up, the sub would hardly play at all. It got very warm very fast so I killed it. I then pulled the sub from the box and it was smoking. I have an old RF amp lying around so I hooked it up and the power light never flickered on it at all. I don't know WTF is going on but it's now beginning to drive me f ing crazy. I really need some guidance on this so please help.
