Alpine's been building quality car speakers for decades, and their latest S-Series S-S65C 6-1/2" component speaker system is no exception. If you've been living with anemic factory sound, this step up in range, tone definition, and power handling will make you giddy just about every time you hop behind the wheel. And if you're really jonesing for the best possible sound quality, hook these speakers up to a nice amp — you won't regret it!
Worthy materials
Alpine's carbon fiber-reinforced plastic woofer cones provide next-level sturdiness but are also agile enough to handle the complexities of the midrange. The big multi-roll rubber surround contributes to reduced distortion for a cleaner sound. Separate silk dome tweeters provide all the precise details that bring out the character of the instruments and vocals. If you've never experienced Alpine sound quality, these speakers are a great place to start.
Grilles are not included; the factory grilles should be suitable for most applications. Optional grilles are available for custom installations.

Features
Woofer Mounting: Without an adapter, the woofers fit standard 6-3/4" applications. Given their required cutout, they will also fit standard 6-1/2" applications without an adapter, but new screw holes must be drilled. Using the included adapter brackets they can be mounted in a variety of standard 3-hole 6-1/2" applications, Ford 4-hole 6-1/2" applications, and non-standard 6-3/4" applications, without any modification.
Tweeter Mounting Options: The tweeters can be flush mounted using the supplied flush mount brackets and rings. Once mounted, the tweeters can swivel approximately 20° for optimum imaging. The tweeters can also be mounted in factory tweeter locations behind factory tweeter grilles using the supplied stealth mounting brackets. (The stealth brackets have a multitude of tabs used for different mounting configurations. When not needed, the tabs can easily be removed. The factory location measurements in the chart below are generally minimums, with some tabs removed.)

I bought these to replace the front door speakers in my 2018 Civic SI. The stock speakers were just awful. When I replaced them with these the sound greatly improved and my ears thanked me. Everything is clear and the bass is clean.
