What Alpine amp will be sufficient enough for two type R 10 inch 4 ohm

Do you think the MRV-F540 will do?

 

No, because those subs would most profitably be wired to 2 ohms (dual 4 ohm in a parallel configuration) which should not be run on a bridged amp due to the amp seeing half the load when bridged ( =1 ohm). The amp will most likely fail. If you want to stick with Alpine, you could use their 500 watt single channel sub amp with the subs in a series-parallel config. 4 ohm total, resulting in 500w (250 to each speaker). I would personally look into some other amp to better match the power to the subs requirements.

 

i am not impressed with alpine amps.. they claim that their "digital" amps are second to none... i have yet to hear one that sound as good as a classic "analog" amplifier...

IMO you do not want digital amplification
