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.

Loved it!
Color: Black, Size: 15.7"
These floating bathroom shelves are exactly what I was looking for. They’re sturdy, well-made, and look really nice once mounted. Installation was straightforward, and all the necessary hardware was included. The shelves hold a good amount of weight and are perfect for organizing bathroom essentials without taking up floor space. They add a modern, clean look to my bathroom and make it feel more organized. Great quality for the price — I’d definitely recommend these to anyone needing extra storage.

Easy install
Color: Black, Size: 15.7", Color: Black, Size: 15.7"
w I recently installed these bathroom shelves, and they completely exceeded my expectations. The quality feels solid and durable, and once mounted, they sit perfectly level without any wobble. I love how clean and modern they look — they instantly elevated the whole feel of the bathroom. The shelving space is surprisingly generous. I’m able to store everything from toiletries to décor pieces without the shelves feeling cluttered or overloaded. The finish also holds up well in humidity, which is a big deal for a bathroom environment. Installation was straightforward, the hardware included worked perfectly, and the shelves feel like they’re built to last. Overall, these shelves deliver both style and function, and I’m extremely pleased with how they turned out. Highly recommended if you want a simple upgrade that makes a big impact.
