How to get the whinning noise outta my radio in a f-150

the whining noise is your engines alternator bearings
they are worn out , the alternator is close to failure
it is barely producing any voltage
( the battery light in the dash only indicates that the alternator is no longer generating any amperage )

an eq is kind of like an amplifier anyway it boost the sound and tailors the sound to your taste. Your eq should have a wiring diagram on the bottom or top of the unit. Your factory radio should have a wiring diagram on top or bottom of it as well. So all you have to do is match left + to left + and right + to right + etc. It's really easier than you think. You just have to pay close attention to the diagrams.

Connect the front channels out from the radio to the main in on the eq.

AOD transmissions are known for the P.R. valve causeing buzzing, whinning noise etc. Lift the truck up try to hear the noise first. Drop the pan check for excessive metal shavings. Fords are also bad about engine noise. Vacuum noises, fan clutches, etc...

Blue goes to your head unit's blue wire. It switches the eq on when the head unit is switched on. It also gets tied into the amp's blue wire (if you are using an amp, and I guess you are since you have a passive eq...). The fact that there are 2 is just for conveinience I think (99% sure) If I recall one may have a white stripe, and the other none. If you want to be sure, with all power DISCONNECTED to everything, and the harness plugged into the EQ, use a multimeter to see if there is continuity (connection) between the 2 blue wires. Then you can rest assured they gave you a secind one just for a "pass thru" to your amps, but inside they are electrically connected, and are essentially the same piece of wire.

ENGINE NOISE PLUG ALL YOUR RCA DIRECT TO AMP BYPASS EQ AND SEE WHAT HAPPEN IF THIS STILL HAPPEN CHECK ALL YOUR GROUND AND RCA MAKE SURE YOU HAVE GOOD CONNECTION

to cut down on noise i would hook it directly to the battery. make sure there is a fuse in the power cord first.

Please rate this solution thanks

possible power steering pump.

CHANGE YOUR REMOTE WIRE TO A SINGLE LEAD, AND THEN CHECK ALL YOUR CONNECTIONS.

GOOD LUCK

FOR EXAMPLE IF YOU WER HOOKING IT TO A CD PLAYER,, YOU WOULD PLUG RCA JACKS IN THE LINE OUT ON THE CD PLAYER,, THEN PLUG THEM IN THE EQ WERE IT SAYS LINE IN OR AUDIO IN,,THEN TAKE SOME RCA JACKS PLUG IN THE EQ TO AUDIO OUT, THEN TO YOUR RECIEVER,, IN CD ,,AND VISE VERSA ,,WETHER ITS A TV OR PHONO,, ANYTHING,,
