Forte GT Head Unit Infotainment System Aftermarket Upgrade - 2021 Forte GT
NOTE: This post assumes the reader has a basic working knowledge of vehicle audio systems and components. This is not as much of a how-to but more of a what to expect and what you’ll need to replace the stock infotainment unit with an aftermarket stereo, and includes a side discussion on options to keep the stock head unit intact and attempt to use sound processors to correct the factory signal. This write-up is for a 2021 Kia Forte GT with the GT2 package - Harman Kardon premium audio, Lane Keep Assist, Back Up Warning System and all other goodies that were present on a fully-optioned Forte GT. This information will work for the ‘BD’ generation Fortes (2019-2021) and might work for the refreshed years 2022-2024. I am not an expert and this thread represents a sound obsessed DIYer’s research and findings, so take it as you will. If you are just looking for information on adding a subwoofer, an amp, and or speakers, this is not the post for you....
