Added EQ, AMP, & replaced factory speakers today.
I have the base 4 speaker system. I ran new wire from amp to all spkrs.
Fired it up and I have no volume control. On 1 it's wide open and on 0 it's off.
Spliced in LOC behind factory deck to what I thought was front left and right.
Uconnect, Sat radio, and everything else works just no volume control.
Somebody tell me where I went wrong!
