!£"!£"$£^%^$$&()*%! or words to that effect! blew up one of my 6x9's, didn't have it turned up much either (half volume) and it went thump thump bzzzzzz. checked with the handy multimeter oops thats it dead so it's going to be buried at some point. thing is the system now sounds better since i disconnected the back shelf. bass from box and 6x9's must have been fighting each other. so i feel a plan coming on!!!
