Alpine 300-Watt RMS Mono Marine-Grade Amplifier @ 2-Ohm or 200-Watt RMS Mono @ 4-Ohm Get big amp performance in a compact, resilient package. With Alpine’s exclusive technology, Dynamic Peak Power (D.P.P.), the KTA-30MW Weather Resistant Tough Power Pack is sure to deliver powerful bass output for subwoofers used in those open cab vehicles and toys. This small and efficient amplifier can be installed with an aftermarket or factory head unit while adding up to 600 watts of D.P.P. power. Its weather resistance makes the KTA-30MW a good choice for use in exposed installations like side-by-sides, boats, open-top vehicles, and motorcycles saddlebags. The KTA-30MW is ready for your adventures. It is weather resistant, rated at IP66 for protection again dust ingress and high-pressure water spray.  Its rugged chassis and high-quality waterproof connector can be used in installations where it will be exposed to the outdoor elements. The KTA-30MW is perfect for when you want to add subwoofer power but don’t have the space for a large amplifier. It is compatible with an aftermarket or factory head unit and provides up to 600 DPP watts to the subwoofer of your choice. The KTA-30MW features Alpine’s exclusive Dynamic Peak Power (D.P.P.) technology which intelligently adjusts the gain to automatically adapt to musical needs. D.P.P. prevents the amplifier from clipping music signals by supplying up to double the power to support power hungry, rhythmic peaks like a snare drums, trumpets, or high-hat cymbals. During these dynamic musical passages, D.P.P. instantly delivers bursts of power to rise to the peak demands of the music and very quickly rolls back down to maintain its efficiency. The KTA-30MW measures just 9-3/16” (W) x 1-5/8” (H) x 3-3/4” (D), so its small footprint lets it fit where most amplifiers won’t, like  under the dash or in the glove compartment, installed under the dash of a side-by-side, placed in the saddlebag of a motorcycle, or used in other places where space is an issue.  Specifications Alpine's Class D amplifier circuit with Dynamic Peak Power (DPP) 300W RMS x 1@ 2Ω, 14.4V, ≤  1% THD+N 600W DPP x 1@ 2Ω, 14.4V, ≤1% THD+N >83dB S/N (ref. 1W into 4Ω) 0.1% THD (ref 1W into 4Ω) 20-400Hz Frequency response (+/-1dB) Cast Aluminum chassis Weather resistant (IP66 rating) OEM-grade connector wire harness Speaker/RCA inputs (selectable, High range=0.5-10V, Low range=0.2-4V) Sound control:LP filter – Off/LP, Fc=50-400Hz @ -24dB/Oct.

Alpine S2-Series 5-Channel Amplifier, 60-Watt x 4-Channel + 300-Watt Sub @ 2Ω, or 40-Watt x 4-Channel + 200-Watt Sub @ 4Ω The Next-Gen Alpine S-Series S2-A55V 5-Channel Amplifier is Hi-Res Audio Certified and able to reproduce up to 40kHz frequency response. This ultra-wide bandwidth coupled with the elevated S-Series design brings out a new benchmark for entry-level performance and price. The Next-Gen S-Series Amplifiers now feature a new selectable remote turn-on circuit, a three-position switch that ensures the amplifier turns on and off at the proper times. This design is crucial with newer, in-vehicle technology and allows for proper integration with any factory or aftermarket system. The amplifier was intentionally designed with sound controls located on the side panels, instead of the top panel, making it easier to access gain and crossover controls when installed under vehicle seats or in shallow-depth locations. Removable end caps were added to cover the side controls and connections, providing a clean, sleek finish to the amplifier. With its versatile 5-Channel design, the S2-A55V Amplifier is the perfect solution to power your sound system all in a single chassis. This amplifier delivers crisp and clear audio to up to four speakers plus an additional subwoofer to give your system a complete audio upgrade. Features Hi-Res Audio Certified (Up to 40kHz) 5-Channel Amplifier   Alpine’s Class D Amplifier Circuit   Two-sided terminal layout   Built-in Selectable/ Adjustable Crossovers  Optional Remote Bass Knob Compatible (required RUX-KNOB.2 or RUX-H01, sold separately)  Specifications Dimensions: 11.9” W x 2.25” H x 8.25” D Weight: 7 lbs Power Rating: 14.4V, < 0.1% THD +N Power Output: 40W x 4 + 200W x 1 @ 4Ω, 60W x 4 + 300W x 1 @ 2Ω Bridged Power: 120W RMS x 2 @ 4Ω S/N Ratio: >83dB Frequency Response: 20Hz – 40kHz Damping Factor: >100 Alpine S2-A55V Manual
