Yesterday outta nowhere one of my subs just stopped workin completley but the other one was fine. I pulled her out today and disconnected the wire from the sub and the port that runs to the clips that runs wire to the amp, and put new ends on the side connecting to the port, then put the wires back to the sub. Worked long enough for me to feel good about fixing it, then stopped working again. Any help? Speaker is not busted i checked it up and over and my testers says theres power running to the port connection inside the box.
