I just installed a 2 channel hifonics amp in my car to run my door speakers. Everything worked fine the first day but now when I trun up the volmue I lose sound to my driver side door speakers. when I switch the RCA around the problem switches to the other side. Just wondering if anyone know what the problem could be beside the amp itself... please help!! //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif
