KEY SPECS
Hi-Res Certified
Using “trickle-down” technology, inspired design, and performance cues from the Ultra-High-Resolution AlpineF#1Status system, the Next-Generation Alpine S-Series Speakers are now Hi-Res Audio Certified and able to reproduce up to 40kHz frequency response. This new benchmark in sound quality elevates the Next-Gen S-Series Speakers resulting in a more accurate and natural sound at an entry-level price point.
Reliable Performance
Crafted with a unique combination of Poly Propylene, Glass Fiber, and Mica Cone materials, the S2-S65 is designed for lightweight construction, high output, and low distortion, giving you a clean and accurate audio experience.
HAMR Surround
Alpine-exclusive High Amplitude Multi-Roll (HAMR) surround technology is integrated into the speaker design which allows for maximum cone movement, delivering powerful and accurate bass notes.
Protect Your Speakers
The S-Series S2-S65 is compatible with the KTE-S65G Speaker Grille (sold separately). This sleek and stylish grille will not only add a visual upgrade to your speakers but also provide protection against any damage.
6x9" Coaxial Speaker Pair
Coaxial 164x235mm (6″x9″) kit, built-in crossover, rotating tweeter. Grilles included. The ideal add-on to your system, in rear deck location. Deep bass too.

If you need an 8-inch subwoofer that can create outstanding bass in extremely small enclosures, the 8W3v3 will do the job and surprise you with its power and accuracy. It employs the same technologies as its larger diameter brethren to deliver a whopping 0.375 in. (10 mm) of controlled, one-way, linear excursion.
The 8W3v3-4 is best used with amplifier power in the 75W - 250W range and is optimized to operate in a tiny 0.30 cu. ft. (8.5 l) sealed enclosure, or a 0.35 cu. ft. (9.9 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.

Safety Notice
Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performance speaker can exceed this level. Please exercise restraint in its operation in order to preserve your ability to enjoy its fidelity.
When installing a subwoofer in your vehicle, it is extremely important to secure the enclosure firmly. We recommend bolting the enclosure through the metal of the floorpan or the frame of the vehicle with large diameter washers for reinforcement. If an enclosure is not firmly attached, it can become a projectile in a collision. This is particularly important in a hatchback, station wagon, sports utility vehicle, or van.
