I do like the '17 door panels, and the way the switches are turned perpendicular to the driver.

I reached out to Rod Birch from Car Audio Innovations. I wasn't going for crazy sound, but a good upgrade. Per Rod, the stock speakers are pretty good. I'm sure upgraded speakers are better, but since I wasn't looking to break the bank, I went with a Pioneer head unit and new amp (and a backup camera). It made a huge difference to the sound and the speakers do sound pretty good to me. Our cars also require the module to integrate the aftermarket unit with the factory fiber optics. Rod sells Kenwood and kits with all of the parts, wiring, brackets, etc.... complete with full instructions. I didn't go that route because I don't have anyplace to work on my car and most of my tools are in storage.

per their website

New speakers are not required. The factory speakers in all of the cars that are not "base" systems are actually quite capable and respond well to the extra power that a new amplifier can supply. However if you are expecting top level performance, you really should consider replacing your speakers as well as adding a subwoofer.

Vehicles equipped with the "base" radio system have only a single low quality 6" speaker in the door instead of a high performance 8" woofer and 4" midrange component set in each door. Vehicles with these audio systems are inherently anemic. Upgraded speakers are recommended.
