Frequently Asked Questions - Honda & Acura Radio Installation
|
What wiring harness do I need for my Honda Civic aftermarket radio? It depends on the year. For 1998-2005 Honda Civic, use our AHH-70-1721 series (replaces Metra 70-1721). For 2006-2011 Honda Civic, use our AHH-70-1722 series (replaces Metra 70-1722). For 2012+ Honda Civic, use our AHH-70-1729 series (replaces Metra 70-1729). All are available pre-wired for Pioneer, Sony, and ATOTO head units. |
|
What is the difference between the Metra 70-1721, 70-1722, and 70-1729? The Metra 70-1721 fits 1998-2008 Honda and Acura vehicles (Civic, Accord, CR-V, Element, S2000, and more). The 70-1722 fits 2006-2012 Honda Civic, CR-V, and select Acura models. The 70-1729 fits 2008-2019 Honda Accord, Pilot, CR-V, Crosstour, and others. Our pre-wired versions add a direct plug connector for your specific head unit brand, eliminating the need to solder. |
|
Can I install an aftermarket radio in my Honda without cutting wires? Yes! All of our Honda wiring harnesses are 100% plug and play. They connect directly between your Honda factory wiring and your aftermarket head unit - no cutting, splicing, or soldering required. This preserves your factory wiring so you can always revert to the stock radio. |
|
Can I keep my steering wheel controls with an aftermarket radio in my Honda? Yes! Our Sony harness models include wiring for Honda steering wheel audio controls built in. For Pioneer and ATOTO installations, pair our wiring harness with the steering wheel control connector (AHH-1922) and an SWC interface module like the ASWC-1. Sony and many Android head units can read the steering wheel signals directly without an extra module. |
|
Do I need an antenna adapter for my Honda? Many Honda and Acura vehicles use a factory antenna plug that does not match standard aftermarket radio antenna inputs. Our 40-HD10 and 40-HD11 antenna adapters bridge the connection so you maintain full AM/FM reception. Check your vehicle in our compatibility database to see if you need one. |
|
Can I add a subwoofer to my Honda without replacing the factory radio? Yes! Our Honda amp installation kit (AHH-1777) lets you tap into the factory audio signals to add an aftermarket amplifier and subwoofer without cutting any OEM wiring. It's a plug and play T-harness adapter for select 2008-2019 Honda vehicles. |
|
Are Honda and Acura wiring harnesses the same? Honda and Acura share many of the same radio connectors and wiring configurations. Our AHH-70-1721, 70-1722, and 70-1729 harness families all fit compatible Acura models in addition to Honda vehicles. For Acura vehicles with factory amplified audio systems, we also offer the AHH-7189 amplifier bypass connector. |
|
How long does it take to install a Honda plug and play wiring harness? Most of our plug and play Honda wiring harnesses can be connected in under 15 minutes. The wiring harness is the easy part - removing the factory radio from the dash is usually the most time-consuming step. No special tools or soldering equipment are needed. |
