Can any one help me with the factory radio wire color diagram for car listed above FE? It has no factory amp so I’m trying to put in a converter for my subs?

Hello, I am trying to find a wiring diagram for my 2019 Kia Optima LX+ factory stereo. Its a 7" touch screen with the back up cam, android auto but no UVO and no Nav. I have purchased an Audioconrol LC2I to run to my Amp's while keeping the functionality of my stock Radio and need to hook it up however, I'm not sure which color wires are for which set of speakers along with the accessory cable.

Hi,

The schematic is three pages long. I had to break each page into 3 parts to make it readable for you, but I did overlap the pics so you could follow them. This is the entire system.

Let me know if this helps.

Take care,
Joe

Hi,

I would be happy to get that for you, but I need more information. If you look at the attached picture below, I included all the radios for this model year. Several are without nav. Can you identify which one is yours?

Hi, I have Navigation but stock speakers just 6 speakers and I'm trying to find the wiring diagram to install an amp using hi to low converter. I can't find anywhere on the internet. I Have the car listed above Sx. Also it would help a lot if you can help me identify which speakers are full range and mid range. Thanks in advance.

Thanks for visiting 2CarPros.

The speakers in the doors will be full range. I'll post the diagrams for this system below for you. If I can help further just let me know.

I can barely see the diagram I can only distinguish the different colors, so all door speakers are full range? It would be way easier for me to use the rear speakers for hi input signal.

Hey everyone!

I have the vehicle listed above s with the uvo without Harmon kardon.

I’m looking to tap the speakers at the radio harness to add a lc7i and a 4-channel. I love my stock head-unit but I’m not a fan of the sound it produces.

I’ve searched for hours with no luck.

Anyone happen to know which of the 2 plugs on the back of the radio holds the keys to my success?

Hello again,
I thought I included the wiring diagrams for you in the diagrams down below earlier, but for some reason they did not make into the diagrams. I apologize for the mix up, and now they should be included in the diagrams down below.

Thanks,
Alex

Hello again,

I would almost assume so. I tried to pull some 2019 wiring diagrams for you, but they have not been made yet. I apologize for this. I can say that on an aftermarket stereo switched power would be the red wire, ground would be black, right rear would be purple wires, and left rear would be the green wires. On both speaker wires the black striped one would be the negative wire. But that's not helping here. You can look at the wiring diagram and compare your vehicle's wires and if the wires match, then you are golden.

Thanks,
Alex

Hello, I'm Danny.

Here is a radio/navigation wiring diagram based off a 2019 Kia Optima 2.0 hybrid. If this is not your vehicle you will need to be more specific and start a new question including all your vehicle information. I've attached the pictures below. Hope this helps and thanks for using 2CarPros.
