How do I know if my car uses a powered Antenna?

Question

I am wiring up an aftermarket stereo. I have found the Constant power, switched power "both red" and the ground "brown". I will be using my own speaker wire.
The harness the stereo has the yellow power, red power, black ground, orange ill, blue acc?/antenna? and a yellow/black mute.

I am going to be wiring in an amp as-well so I will need a remote wire to the deck.

But I do not know if my car has powered antennas "It actually has two" if it does how do I know what one it is?

So, if my car has a powered antenna where do I hook it up to and where do I hook the remote wire up to?

10 points to whoever can help me.

Answer 1

Look up the wiring color code for your specific vehicle. There are many online databases that have such information. This one will tell you if the OEM audio system uses a "powered" or "amplified" antenna and identify the appropriate wire in the color code.

Aftermarket head units generally follow the CEA color code.



12V+ Constant - Yellow

12V+ Switched - Red

Ground - Black (sometimes with spade terminal)

Power antenna - Blue

Remote - Blue/White (sometimes with slide terminal)

Left Front Speaker Positive - White

Left Front Speaker Negative - White/Black

Right Front Speaker Positive - Gray

Right Front Speaker Negative - Gray/Black

Left Rear Speaker Positive - Green

Left Rear Speaker Negative - Green/Black

Right Rear Speaker Positive - Violet

Right Rear Speaker Negative - Violet/Black



If your head unit does not have a dedicated remote lead, I'd recommend using the switched or accessory lead. If you use the blue power antenna lead, it's possible that the amp will only come on when AM/FM is selected as a source. If you use the switched lead, the amp will come on when the vehicle ignition is on (or in the accessory position).

Power Car Antenna

Answer 3

The blue wire (probably a stripe of white as well) will most likely be your remote wire. It tells the stereo to power on when the vehicle's "accessory" power is turned on. If the antenna's are powered, this should be handled by the remote power and the accessory being turned on. You should only have to plug the antenna in to the stereo by the thicker black antenna wire. There should be a remote wire from the amp to the stereo, as well as an RCA cable.



You shouldn't have to do anything extra for the antenna to work how it is supposed to. All you should have to do with the antenna is plug in the cord at the back of the stereo for the antenna signal.

Answer 4

Amplified Car Antenna

Answer 5

You can use the blue antenna wire to switch the amp off and on or to raise/lower a power antenna. The yellow is a constant hot for the radio stations. The red should go to a switched power source; Black to a real ground.

Answer 6

the hot radio would desire to have a cord (blue with white stripe) wich is the distant and this cord is going hooked as much as the blue/white cord on the producing unit adapter wiring harness. you are able to hook it as much as the purple acc cord yet whilst your new unit has the distant cord I recomend to apply it thats what its for.
