Finally I've got my system started

i got the same problem with my audio control matrix, amp gain all the way down and gain on the matrix lil over half way i can hear a hiss/whine from front speakers, with the gain below half on the matrix no noise, grounds all good but im not using a head unit, im streaming through blu tooth from my ipad

 

were you able to get rid of the noise? was the hu the problem?

 

to be honest I haven't worked on it since my last post, I've been super busy. I will get to it soon hopefully and will post up results

 

Has anyone been able to find a solution to the humming problem? Has regrounding the head unit to a different location worked?

 

Post #6 goes over the easiest way to get rid of this hiss
