ok.
from what i have figured out i am almost positive that it is my headunit ground.
i have switches for the highs amp and sub amps.
when only the sub amps are on i can hear the blinker sound through the subs
i can a constant whining sound through the speakers
its gotten so annoyed that i want to fix it.
sub amps and high amps are grounded to the battery grounds through buss bars.
I haven't ever had the problem before and i know quite a few others that have had the problem and regrounding the head unit worked
before i reground the head unit i wanted to make sure it was the problem so if anyone has more knowledge in this area please let me know
