I NEED HELP

I recently added a new head unit into my a6 all pekers were working fine and then i added my amps and then my rear speakers just stopped and dont have a clue how to get them going can someone please help!!!!!!!

 

my 99 is very picky on which speakers work.
at times if i hit a bigger pothole some of my speakers shut off, hah
maybe same thing is happening to you :]

 

yea maybe and it aint as if there aint big enough potholes in ireland to do that to it but i wouldnt mind my amps arnt connected to the rear speakers atal i have a whole new system in the boot so maybe your right but they just went off while stationary so i dont know
