Alpine's been building quality car speakers for decades, and their latest S-Series S-S40 4" speakers are 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 a boost in sound quality, hook them up to a powerful aftermarket stereo or amp for increased performance.

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. Their high amplitude multi-roll rubber surround contributes to reduced distortion for a cleaner sound, while silk dome tweeters give you 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.

Q
can I pair these to an alpine pwd-x5 powered sub?

I see no reason why not, Austin. The Alpine PWD-X5 is a really special unit, considering it does have the 25-watt 4-channel amp built-in to drive your full range speakers. The Alpine S-Series 4" 2-way car speakers can handle 45-watts RMS, so they are a great pair!

Q
I would like to add this ease to my 2021 Bronco to replace the B&O speakers. Can I use this speaker in all three dash locations and the rear pods? And what do I need to attach the wires? Thanks

For additional details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle.
