Theater Amp


Multi-channel DVD sound is an awesome experience in your home — now imagine how great it'll sound in the enclosed space of your car. Wonder no more — the MRA-D550 Digital Theater Amplifier, controlled by a compatible Alpine in-dash stereo, will anchor your multi-channel car audio/video system, delivering deep, realistic sound from your recordings that you have to hear to believe.

The amp's all-digital design delivers 60 watts to each of five channels, supplying the front, rear, and center channel speakers of your system with plenty of clean power. Two inputs allow you to hook up multiple digital sources (like a DVD player or a game system) while built-in processors convert the digital info into surround sound. Built-in Dolby Pro-Logic II processing does a great job of enhancing the sound of your standard CDs.

The MRA-D550's heavy-duty internal components produce rock-solid power, and extra-large capacitors deliver additional current when needed to fuel musical peaks. A unique circuit design greatly reduces internal noise, keeping the signal clean for better performance from your speakers. Alpine's Bass Engine tone adjustments allow you to fine-tune the sound to perfectly match your vehicle. You can control the MRA-D550 with an Alpine GlideTouch CD player, for touchscreen control right from the front seat.
