OK... So I am trying to finalize my install and I am getting frustrated because I have a little bit of noise (static hum & clicking when I press the volume up/down)
Here is how I ran my wires:
Driver side: power, remote
Passenger side: sub RCA Patch, Speaker RCA, & both front speaker wires (i ran the door speaker wire across the dash and down the right side)
Here is my wiring set up:
Head Unit Power Harness and what each is spliced to
“standard†refers to the regular function to function connection from h/u harness to vehicle adapter harness.
“Capped†refers to wires not hooked up to anything.
12v battery/Constant (yel) – standard
12v ignition (red) – standard
Dimmer (org/wht)- standard
Power Antenna (blu/wht) – standard + amplifier remote + antenna remote
Ground w/ stud (blk) – standard + h/u parking brake(lr grn) + h/u mute (yel) + chassis grounded
Car Speed Signal (pk)- capped
Reverse Gear Signal (vio/wht)- capped
Parking Brake (ltgrn)- standard + h/u parking brake(lr grn) + h/u mute (yel) + chassis grounded
Mute (yel) – chassis ground (avic bypass where pin was moved)
Left Front Positive(wht)- capped
Left Front Negative(wht/blk)- capped
Right Front Positive(gray)- capped
Right Front Negative(grey/blk)- capped
Right Rear Positive (vio)- standard
Right Rear Negative(vio/blk)- standard
Left Rear Positive (grn)- standard
Left Rear Positive (grn/blk)-standard
Is it possible that the ring terminal that is grounded to my chassis isn't enough for all that is being grounded? I window spliced the wires into the main ground wire and used an ultrasonic welder to do that. Should I try to ground each wire individually?
Here is some more info when I troubleshot:
-Noise doesn't get louder when accelerating
-Power is not by the signal wires (the driver side speaker wires does however cross it perpendicularly)
-I do have two grounds: one with a ring terminal & one that goes into the factory harness. They are both spliced together. Should I cut the factory one?
-I have no service loops.
-I didn't have this noise until after I installed the front speakers and the amp wire kit (I didn't have the amp or sub, so I just had the wires and capped off until I got in the amp)
-I have isolated the problem away from the amp wiring, so it has to be something with the headunit and the wiring.
-I had the headunit install and didnt have this noise.
any suggestions?
