The Alpine MRP-M500 is a mono channel power amplifier that delivers up to 500 watts. Sound quality and control is protected by a subsonic filter, a low-pass filter, non-fading pre-amp output, and a variable bass boost. The system is designed to be easy to install and easy to upgrade. It includes preamp and speaker-level inputs to connect directly to any head unit - without the need for external converters -- and end caps that protect wiring connections to keep the system in great shape. With power comes temperature and the thermal management processor is included to keep that under control, save energy while not reducing the sound performance.
