Alpine HD-Series 12-Channel Class-D Full-Range Hi-Resolution Automotive-Grade Amplifier, 50-Watts x 8-Channel + 80-Watt x 4-channel @ 4-Ohms

Using expertise gleaned from over five decades of crafting premium car audio products and trickle-down engineering and design from the Ultra Hi-Res AlpineF#1Status system technologies, the Alpine Status system features exceptional tooling and rich build quality for the best possible sound reproduction. Each component was hand-picked from the highest quality materials for the highest in-class audio performance, that when used as a complete system, can achieve 192kHz/24bit playback.

Building a sound system while overcoming acoustical challenges in the interior environment of the vehicle is no easy feat, however, the HDP-D90 14-Channel Hi-Res Digital Sound Processor Amplifier provides flexible system building and Hi-Res processing power up to 192kHz/24 Bit for an infallible listening experience.

Custom developed for Hi-Res Playback, the HDP-D90 has a 192kHz/64Bit internal sampling rate and an ultra-wide audio bandwidth of 10Hz-110kHz for recording studio-level sound. Intentional designs, like a copper-plated chassis, bring the signal-to-noise ratio up to >110dB and minimize noise and distortion during playback for complete music fidelity that’s true to the original source.

The HDP-D90 includes multiple source inputs for flexible system building for the option to retain a factory head unit, add an aftermarket head unit, or the Alpine Status HDS-990 Digital Media Controller. For older vehicles with no source player, the HDP-D90 can also function as a standalone music source and can receive music sent directly from a smartphone with Bluetooth® wireless streaming.

When paired with the Hi-Res HDS-990 Digital Media Player, you unlock even more control options for your processor while getting the highest-quality playback possible in your vehicle.

With 12-channels of amplifier outputs, the HDP-D90 can be used as a standalone source to power a 2-Way Speaker System, or for a more dynamic listening experience, includes 10- channels of RCA output for adding additional amplifiers to power a 3-way speaker system.

The Alpine Status System is sold separately and can be used to build a custom sound system. For best results, install the complete Alpine Status system together as a full system to achieve the highest in-class audio performance only second to the Ultra High-Resolution AlpineF#1System.

Great watch for the money
Color: Stainless Mesh/ Blue Dial
Looks great. I swapped out the band for a leather strap. Nice watch, well designed. My other eco drive has been going strong for 15 years or so without a hitch. So I have high expectations for this one.

Flimsy, small face
Color: Stainless Mesh/ Blue Dial
This watch doesn’t feel like the typical eco drive. The face is small, it’s very light and the mesh band was a pain to clasp. I returned it the day I got it.
