MRX-T15 - 2 channel digital amplifier

The new X-Power series amplifiers are now all digital. These amplifiers are the followers of the Alpine V-Power series, using a variety of PDX amplifier technologies to deliver impressive power and bass. These digital power sources are very efficient, they are much more compact than you might expect. Advanced thermal protection means you can listen to music loudly with amplifiers, and the music never stops.

                Digital technology

                Digital technology

                The X-Power series amplifiers use digital technology similar to the PDX series, delivering high efficiency. In addition, such excellent audio performance is characterized by low distortion, high attenuation factor and high signal-to-noise ratio.

                Easily customizable to any system

                The amplifier has speaker level inputs that allow it to be connected to a factory-installed control unit that has no pre-amplifier outputs. This way you can enhance the original system with more power and better speakers.speaker level inputs

                Remote sensing

                The remote monitoring function automatically turns on the power when the amplifier detects an incoming audio signal. No separate long distance is required.

                Smaller outside dimension

                PDX digital technology means greater efficiency, so X-Power amplifiers are 29% more compact than previous models, making installation even more convenient.

                Effective heat protection

                If the amplifier gets too hot, a thermal protection circuit applies, which reduces the output power by a few steps without interrupting the music. Surge and overcurrent protection is also provided.

                Bass Control Button (RUX-KNOB)

                Just add the RUX-KNOB (sold separately) and you have full control of the bass from the dashboard. With this driver, you can control multiple amplifiers through simple adapters with telephone wires.
