The amp is a MRV-F345 - specs can be found here : http://www.crutchfield.com/p_500MRVF345/Al...tures_and_specs

The MRV-F345 4-channel amp produces 75 watts RMS per channel — perfect for driving most component systems or high-quality coaxial speakers. The clean power output allows the speakers to produce the fine detail and nuance that'll separate your system from the rest of the pack. In bridged mode, the versatile MRV-F345 delivers 300 watts from channels 3 and 4 (perfect for running a sub), while you can use channels 1 and 2 to drive the front speakers.
