This page provides the complete 2006–2011 Honda Civic radio wiring diagram for the 8th generation Civic (chassis codes FA, FD, FG, FK, and FN). Use this guide when replacing the factory head unit or troubleshooting audio issues in a 2006, 2007, 2008, 2009, 2010, or 2011 Honda Civic.
The 8th generation Civic introduced a dual-level dashboard design and a significantly more sophisticated factory audio system. Si and EX-L trims offered a factory subwoofer and amplifier on some configurations. When upgrading the head unit on a factory-amplified 8th gen Civic, you will need either a line output converter or a harness adapter that bypasses the factory amplifier. Steering wheel audio control retention also requires a compatible SWC interface module.

Frequently Asked Questions
Does the 2006–2011 Honda Civic have a factory amplifier?
Select trims of the 8th generation Civic include a factory amplifier. The EX-L with navigation and some Si configurations added a 7-speaker premium audio system with an external Amplifier. Lower trims (DX, LX, EX without navigation) use a passive, non-amplified speaker system. The presence of the factory Amplifier significantly affects how the head unit must be replaced.
Where is the factory amplifier located in a 2006–2011 Honda Civic Si?
On 8th generation Civic Si models equipped with the optional premium audio system, the factory amplifier is typically mounted in the trunk behind the rear interior trim panels. The Si’s amplifier drives the door speakers and a factory Subwoofer (where present). Confirm whether your Si was ordered with the premium audio package, as it was optional and not all Si models include it.
What wiring harness adapter fits a 2006–2011 Honda Civic?
The 8th generation Civic uses an updated Honda radio connector that differs from earlier generations. Metra 70-1729 Wire Harness Adapter is the correct adapter for most 2006–2011 Civic applications. For amplified trims, an additional amplifier bypass harness or integration harness is required alongside the standard radio harness. Always verify your trim’s audio configuration before ordering parts.
What size are the factory speakers in a 2006–2011 Honda Civic?
The 8th generation Civic uses 6.5-inch speakers in the front door panels and 6 1/2″ Speakers in the rear doors on sedan models. The Si coupe has a slightly different rear speaker arrangement. Tweeters are present in the A-pillars on EX and above trims. The door speaker depth clearance in this generation is generous, accepting most standard-depth aftermarket 6 1/2″ Speakers without issue.
How do I retain the factory backup camera in a 2006–2011 Honda Civic after replacing the radio?
Backup cameras were not factory-standard equipment on the 8th generation Civic. If your vehicle has a backup camera, it was added as a dealer accessory or aftermarket installation. To retain it after replacing the head unit, you will need to connect the camera’s video output to the aftermarket radio’s rear camera input and configure the radio to display the camera when reverse is engaged.
