Upgrading your car stereo shouldn't mean losing your factory bass.
This subwoofer retention harness is designed specifically for Honda Civic and CR-V (2012–2016) to help you keep your original subwoofer working when installing an aftermarket stereo or Android head unit.
Instead of cutting wires or dealing with complicated rewiring, this SUB adapter connects directly to your vehicle's factory 8-pin plug and converts it into a standard RCA subwoofer output. That means you can easily link your new stereo to the factory subwoofer system — clean, simple, and hassle-free.
Whether you're upgrading to a touchscreen head unit or improving your in-car audio system, this cable helps maintain the deep bass response you already have, without additional modifications.

Perfect for:
Aftermarket stereo installations
Android head unit upgrades
DIY car audio projects
Maintaining OEM sound performance
With a compact length and plug-and-play design, installation is straightforward even for first-time users. No special tools required, no risk to your original wiring.
Keep your upgrade simple — and keep your bass.
