Hey guys, I am looking at purchasing the RFX3000 and RFXMR5BB, but have three questions I could not answers for through the RF website.
(1)  The RFX3000 is rated 50W x 4.  Is that continuous or maximum?  I ask because with the spec'd 10 amp fuse x 14 volts = 140 watts, so the 50x4=200 watt rating seems high...
(2) What is the %THD 20-20KHz for the continuous wattage rating?
(3) Can I put the two left and two right channels in series to effectively double the output to a pair of speakers?  I was able to do that with my old Rockford Fosgate amps, don't know if I can do the same with the RFX3000...
