Alpine® Mono Power Density Amplifier

Remote Bass (RUX-KNOB or RUX-KNOB.2) Compatible

Alpine’s top engineers from all over the world gathered in Alpine headquarters to deeply research and evaluate sound systems from both the aftermarket and high-end OE manufacturers. Many systems today have incredible dynamic range and reach sufficient volume levels, but lacked the reality of instruments and spatial imaging. As a result, Alpine ID was born, a sound philosophy that continues to inspire us to create a new level of sonic performance.

Or Alpine ID for short, is the new Alpine global sound culture with an evolutionary approach for solving what’s missing in most car audio systems these days: great spatial imaging and depth of sound stage. It centers on developing matched sound systems with core components that work together to achieve greater realism in the sound stage while maintaining great dynamic range and accuracy.

Keeping The Heat Down While Faithfully Reproducing Music

At the core of the X-Series Amplifier’s chassis is a solid cast aluminum heat sink which keeps the amplifier cool when performing at its peak power levels. Excess heat is removed from the amplifier through the newly designed heat sink profile which both improves airflow and increases surface cooling area. The fan-less channels located on both sides of the amp allow for convection flow of air; hot air naturally rises out from the top of the amplifier, which causes a vacuum that sucks in cool air from below. This smart design allows for continuous thermal control for an uninterrupted listening experience.

X-Series Amplifiers come with their very own birth sheet which reveals each amplifier’s true power rating.

High Performance While Retaining Class-Leading Power Density

X-Series amplifiers are built on a new Alpine-proprietary circuit design that achieves class-leading power density and reliability while performing at the top of its class. By simplifying the circuit topology, Alpine is able to ensure the cleanest possible signal path. While the simplicity of the circuit contributes to a great sounding signal, we added an exclusive dual feedback loop that corrects signal distortion. This clever design results in a frequency response that not only meets the Hi-Rez audio standard of 40kHz but even extends up to 60kHz. The amp maintains a very low phase shift throughout the music spectrum which allows your music stay faithful to the original recording with realism that puts you in the center of the performance.

The new R-Series amplifiers produce accurate imaging and dependable power. Use them with the R-Series speakers and amplifiers for a loud and fun experience.

Alpine® R-Series Mono Power Density Amplifier

CTA-2006-B Power Rating: 500W RMS x 1 (4omh, 14.4V, < 1% THD+N); 750W RMS x 1 (2ohm, 14.4V, < 1% THD+N)

Frequency Response: 10Hz to 400 Hz (+/- 3dB)

Remote bass knob compatible (requires RUX-KNOB.2, sold separately)

The R-Series amplifiers utilize Alpine’s advanced amplifier platform that takes the classic Class-D amplifier circuit and adds dual post-filter feedback loops for unmatched accuracy and control. This technology., originally launched in the premium X-Series amplifiers,, produces efficient power with enhanced dynamic range, qualifying the R-Series amplifiers to be Hi-Resolution Audio compliant.

This new technology minimizes audible imperfections like excessive phase shift and internal noise which can deteriorate sound quality. With an incredibly low phase shift of 46°, the R-A60F 4-channel amplifier delivers accurate imaging compared to well over 100° of phase shift by a competitive amplifier model. This superior phase curve ensures a proper sound stage among the singers and instruments.

R-Series amplifiers have a built-in bandpass filter which lets you design an active speaker set-up without a separate processor. Improve the sound quality of component speakers by ditching your passive network.  Avoid added phase shifts and power losses by individually powering each component and assigning your own frequency bands for the incredible sound you’re looking for.

The “R” line of speakers and subwoofers have a heritage of sound quality you can hear from a block away, and the newly added R-Series amplifiers are no exception.  Aside from their best-in-class performance, these amplifiers are tuned to emphasize the characteristics of the R-Series speakers and subwoofers, giving you that legendary R-Series experience .

S-Series amplifiers are your sound system’s workhorse. With unmatched reliability and budget-friendly prices, these amplifiers are the better choice in performance value.

Alpine® S-Series Mono Power Amplifier

CTA-2006-B Power Rating: 330W RMS x 1 (4ohm, 14.4V = 1% THD+N); 600W RMS x 1 (2ohm, 14.4V = 1% THD+N)

S/N ratio: >85dB (ref: 1W into 4 ohm), >105dB (ref: rated power into 4 ohm)

Perfect for beginners and enthusiasts alike, the S-Series amplifiers have the technology to improve your music experience yet are still friendly on your wallet. Used in conjunction with our advanced S-Series speakers and subwoofers, they create a complete sound system that takes your in-vehicle music experience to the next level.

The S-Series amplifiers are designed to fit anywhere.  Measuring at 8”, these amplifiers can be mounted under seats or behind panels.  Though they sport a compact footprint on the outside, they produce impressive power on the inside. At 600 watts RMS, the S-A60M is a powerful partner to drive the versatile S-Series subwoofers.

The S-Series amplifiers contain technology that was previously only available in our premium line up of amplifiers, the R- and X-Series models. The S-Series models are based on Alpine’s intelligent amplifier platform that ensures superior sound reproduction and precision imaging. With an improved heat sink, and protection circuit design that eliminates thermal shut-down, your music will keep playing no matter where your drive takes you.

With Alpine’s exclusive technology, Dynamic Peak Power (D.P.P.), the KTA-30MW is sure to deliver powerful bass output for subwoofers used in those open cab vehicles and toys.

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.

A Sound System Boost Without The Big Space Commitment

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 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..

Half The Size Of Our Smallest Traditional Amplifiers

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.

The KTA-200M Mono Power Pack Amplifier produces 400-watts of Alpine’s Exclusive Dynamic Peak Power for big subwoofer power in a small space.
