well if the amp was blown then it would start smelling like something burning...its kind of tricky to tell if its blown cause sometimes it might still sound. im not a tech in this so i might not be right but i learned from my past expierences....it might even be the speakers themselves. just because its a new system or the amp and the speakers go together doesnt mean it wont burn out on you....tell me this...did you check for a funky smell comming out the amp?? did you check the ground wire,power wire,remote wire,aux wire,speaker outputs? something might be pinched. and one more question...do your lights dim when you got it turned all the way up? and your battery dies out?
