low buzzing noise after amplifier installation ?

[hotdogpete1]

I have a 2006 Ford Ranger Sport Extended Cab and it came with a single player CD unit. I purchased the upgraded MP3 6-player CD head unit from a Tremor package and also a Sony XM4S four channel amplifier. I installed the Sony under the passenger seat and it fit with plenty of room. With a couple of aftermarket wiring harnesses I adapted the head unit to the amplifier but I had to fabricate patch cables by using shielded two conductor cable to tie in the radio side wires and RCA male adapters for the amplifier low level input side. When I turn the key to accessory the sound is to die for and really works great. My problem is when I turn the key to ON ( without starting the vehicle ) I get a buzzing noise. When I start the vehicle the buzzing noise does not change. Does anyone have an idea of what could be turning on in the vehicle to create this noise? Maybe a fuel pump? I was wondering if I could just buy a power input filter for the CD player and eliminate the noise. Any suggestions would be greatly appreciated. Help, I'm sooooo close on this installation and know I can beat it!

Where is the noise coming from? On my 96 I kept hearing a buzzing noise towards the passenger side firewall. Come to find out it was my blend door.

sounds to me like you may has crosed one of the rca lines over or really close to the power line for the starter and are getting some "road noise".. something like that is going on with mine right now with mine. i me power and ground connected to me starter and am picking up sound from it. i would say make sure you dont have to many lines crosing over one another and go from there..

is it your alternator creating noise? there is a capacitor on your alternator that can go bad and let some noise in. does it go up with rpms?

if your remote amp line and rca cable are too close to the power cable it can cause interference so try running the rca and remote amp out on a diffrent side as your power and ground cables

its just getting your power and rca's crosssed the remote and ground dont do anything.

I am bringing up an old topic because i am having the same problem. My rcas and power are not crossed at all. Everything is fine until i drive, and then the speakers wine and get louder the faster i rev my engine (Before shifting). Can anyone help me? I have never had this as a problem in any cars i have ever had, and its install the same exact way..

/edit

My power wire is ran through my fender..could that be the problem? I did this on my nissan and never experienced a problem.

check your ground, mine did that in my jeep, i rhino lined the inside and just ran a self tapping screw in it, the insulation of the rhino wasnt grounding good enough for 2g wires

also reroute your power wire, i saw a carolla burn up at the gas station because of that. fender rubbed it and created a fire. worst part was the fire burnt the hood release cable and he couldnt pop it to put out the fire
