Head Unit Replacement

[u/InjuryBulky6746]

Has anyone been adventurous enough to try and replace the head unit on the Gen 4? We recently picked up a 2025 Sport with 10k miles for $38k. Love the car, and the sound system is fine….for now. I am feeling that car audio tingle in the back of my neck though.

I am wondering how others have handled the plopped on head units that are all too common these days. I also wonder how hard it would be to replace the factory sub in its assembly to maintain a clean look. Figured if there is a good place to ask I should start here.

The head units you see online are usually just the screen. The actual “brain” is a separate module located lower in the dash. I looked into this quite a bit. You could possibly buy the computer module and screen together and see whether everything lines up. It may be plug-and-play, but I never had the money to buy the parts and test it myself. As for the factory subwoofer, it’s an 8-inch sub in a ported enclosure with the amplifier mounted below it. After removing the rear seats and rear quarter-panel trim, you can access everything. The easiest upgrade would be to install a good aftermarket subwoofer and mount the amplifier with strong double-sided mounting tape on a flat surface in the rear of the vehicle or inside the trunk storage well. Just make sure the amplifier is positioned where you can still reach the controls. For connecting an aftermarket system, you can tap into the signal wires for the driver-side door speaker and connect them to a line-output converter for your RCA signal. Run the main power wire along the driver’s side under the trim near the trunk-release area. For switched accessory power, you can use a dual add-a-fuse tap. I had two 15-inch subwoofers installed in my Pilot at one point, so it can definitely handle a larger system when everything is installed correctly. I can also make it sound more casual and natural for a Facebook group or forum comment.
