Hi Thomas and welcome to the forum. Which model of the Optima do you have? The higher line versions with the HK system has an amp and that is most likely in the trunk under the lining. I am not sure if it is teh right side or the left side but if you push on the lining on the side, most likely closer to the parcel shelf, you will feel if there are things underneath there.

It just says 2020 Kia Optima FE and I looked around in the trunk for a amp but couldn’t find one and it only had speakers in the doors none on the back dash so would I have to tap into the factory radio it self meaning as in take the factory radio out and tap into the speaker wires or is there another way for me to run my sub?

I have the same vehicle. There is no amp located in the car. The only way for you to hook up your subwoofer, would be for you to wire a amplifier to your head unit, then your subwoofer to the amplifier. Good luck and please keep me updated how it went. How easy/ or hard it was to hide all your wiring.

If you're just going to add an amp for a sub, I think it would be easier to install a line output converter like the lc2i. If you're going to add multiple amps for a full audio system then you should definitely add the lc7i.

If you can't find a wiring diagram then next best thing is to remove a door speaker to see which wire colors they are

Hey @Jkemp Would you mind if I were to send you an email as well for the master sheets? I too have a 2020 Kia Optima Special Edition myself that I'm trying to figure out for my system. I'm looking to keep the stock radio and add an amp with a sub and replace all the speakers within the car also, but this is proving to be a little difficult lol! I would super appreciate it! Thanks 😊
