iv been gutting my ICE all afternoon cos the rear speakers cut out a few days ago. My amp has power and turns on and off with the head unit so its not that, i took the amp cover off and all looks peachy inside, the front speakers still work, and iv changed the red & whites over, but nothing! I have an alpine head and changer, standard fronts and alpine 6x9s, and a boss amp. It cut out on a speed bump which meant i thought it was a bad connection, but after changing my red and whites around i dont know what it is now! any ideas anyone?
