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.

Good product. Fits fine. This is not a Toyota part so Air Flow Arrows on filter should face down in a 2015 Toyota Rav4.

It fits, but just barely, so it's good that it is sturdy

First and foremost, this part is a fairly poor copy of the OEM part. It's close enough to look good from about 20 feet away, but on close inspection, it has gaps all around. It doesn't follow the curve of the opening properly, and the contours aren't quite right, making it so the outer top corners aren't recessed the way they are supposed to be (see pictures). Some of the tabs don't interface with their mating surfaces because the part is about 5mm too small in the y-axis (see picture). That said, after ordering another similar knock-off, this one is the better of the two. The matte finish is truly matte. The grill slats are thick and beefy, like OEM. The tabs are stout and flexible, not brittle. After much fussing with installation, you should be able to bend your hood tabs (not that you should have to) so all tabs will lock in place. The hardest part for me was getting the outboard-most tab to properly snap in, since the outer top corner of each grill doesn't sit flush inside the recessed relief where it's supposed to sit.

Why pay OEM prices? These kidney grills fit excellent!
Style: Matte Black Single Slat, Size: E46(2002-2005)4-Door
Was a bit skeptical but the fit and quality are excellent. The do not wobble around or fit loosely. Highly recommended.
