Well after the amp installation I have a tiny bit of noise I can hear during hard acceleration and low volume listening.

I ran the power wire along the drivers sill, behind seat, and into spare tire area.
I ran the RCA's and speaker wire along the passenger sill and into spare tire area.
I left the slack from RCAs behind the passenger seat, and the slack from the power wire behind the drivers seat.
The wiring is all Stinger Pro series.

Amp is Rockford Fosgate 201s 600w. Power and ground are 8 ga. I have the amp grounded here as instructed in Darkknights thread.



What is a common place for the noise to be getting into the system?

 

Could possibly be coming from speaker wires in close contact with electrical system. Ive read to run wires perpendicular to eachother rather than in parallel with b/c this produces a larger area in contact. Give that a shot...if not, maybe someone else can help you better

 

Oh I know how the noise gets in there, but the wires are run on opposite sides of the car (power and audio that is).

Just curious of any known places to get noise on this car.

I might have a bad ground on the HU, but i'm not convinced.

 

Those are not good grounding points for an amplifier. You should never ground to a factory bolt or any welded surface adjoined such as that brace. The problem is a ground loop. A simple way to fix it, if the loop is between the radio and amplifier is to take a scrap piece of wire and connect the radios ground to a better amplifier ground in the back. If that doesnt work, you can take a scrap piece of wire and wrap it around the outer metal jacket of the rca cable (this is the neg. of the rca cable) (leave the rca cable plugged into the radio) Then simply ground the opposite end of the small scrap wire to the radio chassis itself or the radios ground.

usually radios have a small grounding point on the back via a small threaded screw that usually works fine.

Most of the time this will eliminate the loop and the subsequent whine, but not always. Also, check to see if you dont have the gains set incorrectly on the amp, which can also introduce noise.

Hope this helped.

 

it's a ground loop... here's the steps to fix it. First check rcas which are easy , run a new set of rcas like outside the car just to quickly test those - unhook from the amp and the radio and test , still there change the ground on your amp , still there change out the radio or borrow one real quick. otherwise you could have a bad transitor inside your amp.

 

I shall change out the ground on the amp and see what that does for me.

Thanks guys!
