Alpine designed its Status System components for high-resolution audio playback. Their Status Series digital receiver, amp, speakers, and subs were designed to work together and play your 192kHz/24bit digital music streaming files with high-quality, studio-level purity and sonic fidelity.
The HDP-D90 features 14 channels of digital sound processing (DSP) controlled by Alpine's HDP DSP tuning app running on your laptop or PC, or their HDP-D90 mobile phone tuning app via Bluetooth® connection to your device. Each channel features sophisticated sound controls, including a 31-band EQ, a wide variety of crossover filters, phase control, and time delay.
Your car's multi-speaker high-resolution audio system needs lots of power and precise tuning to sound its best — and Alpine's HDP-D90 Status Series amplifier and digital processor provide it with stylish good looks plus practical integration and fine-tuning features. You won't believe how many more details you'll hear that were missing in your music before installing this amplifier, thanks to its high-fidelity digital inputs and sound processing.
The amp provides eight output channels of 50 watts RMS each, plus four channels of 80 watts RMS each — each with a wide, high-definition frequency response that improves your music's realism and presence. It's perfect for powering front tweeters, midrange, and mid-bass components, rear full-range speakers, plus a couple of subwoofers from bridged channels — or whatever other combinations you can dream up.
If you're leaving the factory stereo intact, all the audio functions that were available in your system will still work after upgrading the power of each individual speaker by routing the factory signals through the amplifier. The HDP-D90 can handle pre-processed factory signals up to 80 watts per channel, so even your vehicle's premium amplified system can be upgraded without losing features.
