Did you use more than one ground points ?,if you did so you must have them all in one place.Make sure your ground point is free from paint,grease or rust;you need a nice shiny spot.If you did all that and still have the "noise" you've got a ground loop that in most cases can be removed with a ground loop isolator.I will not promise that the noise will be gone 100% but it's worth trying.Stinger makes a decent one,Monster Cable and many more.Let us know of your progress.

We need some more specifics on your situation. Such as what is the year and model of your vehicle? Are you running a factory head unit? Do you have any external amplifiers installed, and if so, what are they for? (subs, speakers, etc.) And of course model numbers for all your components except speakers (unless you wanna give us those numbers too posted_image

)

Also how did you run your power and signal cables (rca cables. speaker wires)? What side of the car are they on?

my deck is a pioneer deh-p4500mp . i am running 2 amps , a 200 watt and a 400 watt . both are i believe road masters . just cheapies but still . i had the problem running just one of them but i didnt notice it much . with the other amp installed it is real bad . i here my blinkers my fan and my rpms . did like they said an ran the power and the rca jack down opposite sides . the rca's are on the driver side and the power is on the passenger side . i cant really tell if the noise is coming from all speakers . the only place that i know i can hear it is the rear dash speakers which are pioneer 3-way speakers . as for the ground wires i have one amp mounted under the back dash and the other to the deck lid . so one is grounded to the deck lid and the other to the back dash . i scratched the surface so there would be no paint causing it to not a get a good connection . also for the second amp i didnt go al the way to the battery to get power i just hooked up to the other amp which i would think would be ok since it is direct to the battery . i thank you for your responses and ill give them a shot and let you know . and im looking forward to here some more ideas . thank you .
