What size speakers do I need for a 2006 Subaru Outback?

In the 2006 Subaru Outback, you'll find SRxAnd a half-inch full-range speakers installed in both the front and rear door panels. If you're looking to make a significant upgrade, consider replacing the stock OEM speakers with the Focal Kitec165Ks. These speakers, priced at around $800 per pair, offer a frequency response of 60Hz-22kHz, 93dB sensitivity, and a peak power of 160W. The difference in sound quality is something you truly need to experience to fully appreciate the enhanced dynamics they will bring to your Subaru. When upgrading, remember to also invest in high-quality speaker wire if you're swapping them out. Additionally, this presents a good opportunity to think about replacing the outdated head unit that's been in your car for over 15 years. The Outback can accommodate either single or double DIN head units, so you have some flexibility in choosing a newer model.
