Using expertise gleaned from over five decades of crafting premium car audio products and trickle-down engineering and design from the Ultra Hi-Res Alpine-F#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. Powering a Hi-Res sound system without contributing noise during playback requires efficiency and precision and the HDA-V90 was intentionally designed to provide impressive power output to the system while ensuring the purest audio performance. The amplifier’s wide dynamic range capability provides impressive output in a compact chassis that fits most vehicle applications. The HDA-V90 features a high-efficiency digital circuit design that ensures ultra- low distortion levels for precise sound reproduction and superb sound quality. Intentional designs, like a copper-plated chassis and black circuit board, bring the signal-to-noise ratio up to 87dB and minimize noise and distortion during playback for complete music fidelity that’s true to the original source. Featuring technology unique to Alpine, the amplifier features Alpine’s dual negative feedback control circuit to improve linearity for the most accurate sound amplification. This technology also stabilizes the amplifier output while driving the speakers and subwoofers for ultimate reliability. The HDA-V90 features Alpine’s quick- connect power and speaker connectors for quick and safe installation. The one- sided terminal layout and top-panel sound controls give the user quick access to controls on the amplifier. The Alpine Status System is sold separately and can be used to build a custom sound system. Three sets of true 4V preamp outputs are included to add additional amplifiers if more power is needed. 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.

HD-Series 5-Channel Class-D System Amplifier, 100-Watts x 4ch + 500-Watts x 1ch @ 1.5-4-Ohms Thanks to its ability to act as a "one-box solution", the HD900/5 is ideal for installations where space is at a premium and sound quality is the paramount goal. While extremely compact, this amazing amplifier will comfortably drive a complete high-performance car audio system: that is, four satellite speaker systems and a subwoofer system... with a very serious 900 watts of power! Using JL's Single Cycle Control switching design and R.I.P.S. technology, the HD900/5 delivers 100W x 4 to its four main channels, plus a very meaty 500W to its subwoofer channel. Thanks to R.I.P.S., high power can be delivered over a wide range of load impedances, while the tight power supply regulation keeps distortion down, maximizing sound quality. From a pure sound quality perspective, we invite you to compare the real-world, in-car performance of this amplifier to any other amplifier on the market, of any type, at any price. This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and bottom panel. A black powder-coated, gasketed cover is also provided to protect the controls.

RD-Series 5-Channel Automotive Amplifier, 70-Watts x 4ch + 500-Watt Mono @ 2-Ohm Crafted as an all-in-one, total system solution, the RD900/5 is engineered to power a complete audio system consisting of a subwoofer + four satellite system with 900 watts of high-performance sound. Equipped with JL's exclusive NexD™ switching technology, this complete power package efficiently generates a potent 70 watts of crystal-clear audio into 4 ohms, plus a robust 500 watts for a subwoofer system, all from a single compact chassis. Each pair of main channels is also fully bridgeable, stoutly producing 200 watts of full-range audio bliss (into 4 ohms), creating an ultra-powerful 3-channel amplifier. Conveniently located on top of the RD900/5, you’ll find a complement of studio-grade signal processing features, all hidden beneath a removable protective cover. Each pair of main channels is equipped with a 12 dB / octave high-pass filter, with a dedicated low-pass filter for its subwoofer channel. All three crossovers offer continuously variable frequency selection from 50-500 Hz, for precise filtering. Dual-range, differential-balanced inputs are also onboard, capable of accepting most input voltage levels, plus automatic turn-on capability (via signal sensing or DC-offset sensing) for maximum versatility. LED clipping indicators are also standard equipment for each channel section. This all-new, innovative feature lets you easily set your amplifier’s input sensitivity settings, quickly and accurately, with no special equipment needed. The RD900/5 features a durable, black powder-coated finish and a top-mounted, dual-color LED light strip that reports the overall status and condition.
