I went out to my truck today to listen to some music and i noticed it was not as loud as usual so i look in the back and only 2 out of my 4 15's were working. So i checked the wiring and check my amp to make sure it was not overheated and everything was fine the amp was not even warm. I start my truck back up and turn on the music and i notice all 4 are working so i turn the volume up and those same 2 subs quit working again. What is the problem? They only quit working when i turn it up all the way.
