my power wire and ground wire always keep slipping out of the amp terminals and i cant figure out why... It seams like when push the cable in as far as it will go and tighten the allen wrench screw thing this splits the wire in half so to speak and ends up slipping out a few days later. .. anyone else have this problem? or a solution? my box is not secure but it does not move around that much to where i would think that is the problem..
