Frequently Asked Questions
Does the 2016–2021 Honda Civic have Apple CarPlay and Android Auto?
Apple CarPlay and Android Auto became available starting on the 2018 model year refresh of the 10th generation Civic, on EX and above trims. The 2016–2017 Civic did not include CarPlay or Android Auto from the factory. If you have a 2016 or 2017 Civic and want CarPlay, replacing the factory head unit with a compatible aftermarket unit is the most straightforward path.
Where is the factory amplifier in a 2016–2021 Honda Civic?
The 10th generation Civic Touring trim includes a premium audio system with an external Amplifier mounted behind the rear interior panels. EX, EX-L, and Sport trims on some configurations also include amplified systems. LX trim uses a non-amplified passive speaker configuration. The presence of the Amplifier affects which harness and bypass components are needed during a head unit swap.
What wiring harness adapter fits a 2016–2021 Honda Civic?
The 10th generation Civic uses an updated connector system. Metra 70-1729 Wire Harness Adapter covers the base radio connector for non-amplified trims. Amplified trim configurations require an additional amplifier bypass or integration harness. For Civics with the Honda Sensing camera system (standard on all 10th gen models), the factory camera feed must be routed through the aftermarket head unit’s camera input to retain rearview and Honda Sensing alert displays.
What speaker size does the 2016–2021 Honda Civic Type R (FK8) use?
The FK8 Type R uses a unique interior configuration compared to the sedan and hatchback. Speaker sizes and locations in the Type R differ from FK7 hatchback models due to the sportier interior trim and Recaro seat configuration. The Type R does not include a factory subwoofer but has a sport-tuned audio system. Aftermarket audio upgrades in the FK8 often focus on replacing the factory component speakers with high-end aftermarket components given the performance-oriented audience.
Does the 2016–2021 Honda Civic hatchback have rear door speakers?
Yes. The FK7 Civic hatchback includes rear door speakers in addition to front door speakers. The rear doors in the hatchback variant use 6 1/2″ Speakers, the same size as the front doors. The hatchback’s rear speaker locations are a full door-mounted configuration rather than the package-shelf setup found in the sedan, giving a more even surround-sound presentation.
