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.

Needs more cowbell

Can't give these speakers a worthwhile rating yet as I haven't installed the new receiver yet. Looks like I won't be doing that for a while since I hit a deer after only 3 days of speaker use. Jeep is now totalled and it will take me a while to put it back together.

Pros: Easy install, great Crutchfield kit extras really help. Better sound than stock.

Cons: Probably would go with 3x5's instead of a 4" round for dash speakers on a Wrangler.

When I ordered the stereo and speakers I talked to one of the sales person and they were very helpful to explain the best speakers for the install I was doing.

Pros: The sales people had good understanding of what I was doing, very helpful.

Cons:
