 The Alpine MRP-F300 is a 4/3/2 channel power amplifier that offers 50 watts x 4 and 150 x 2, for 4 Ohms, 75 watts x 4, for 2 Ohms.  Some other features are: STAR topology, subsonic filter, non-fading pre-amp output, protection circuits, a power/status LED, a low pass filter, MOSFET power supply, CEA-2006 compliant, gold plated screw terminals, selectable bass boost, speaker- and preamp-level inputs, and a 1 year warranty.  The speaker- and preamp-level inputs make the system easy to install and expand upon -- a good choice for a consumer who wants an overpowered system but doesn't have the money to buy all the pieces right away.  The power of the unit means that it could overheat, so thermal management control is included to save energy and dissipate heat to create a high power system without risking long term functionality.
