Was looking at base amps, Dave made X-force fat boy etc. was looking at for both SSB and AM on 10-11 2x2879's was leaning towards X-Force and saw the Nemesis series I like the looks better with the fan on the inside. same price for the old style.Is one better than the other? was also looking at the prime power series with 4 X ERF7530 it's a little less money but class AB when the other amps are class C I know people say stay away from mosfet amps. not sure what direction to go on amps.
