Essentially they are the same amp, made by the same manufacturer. Everyone says they will fit, but both are slightly longer than your 520. I just ordered the PA amp yesterday because it's a few bucks cheaper.
Same amp. Both are very powerful amps pushing about 140 watts RMS @ 4 ohms. Just branded differently. Both fit in the fairing. Tight but they fit. If you purchase the PA you will have to take off the handles for it to fit.
But I guess my main ? is if it holds true to spec? Is that according to actual specs the PA RZ4 2000D & 3000D are a much higher RMS rating at 4 ohms than the SS PN4.1000D does this hold true? and or is either one better being a cleaner slash no distortion sound?
I have done bench tests, in the sticky.
Comments regarding specs are there as well...
PA amps specs are highly overrated, SS is pretty much on spec.
Hence think about PA as SS (brother and sister amps). Never opened them but pretty much sure they are identical on the inside.
Only pay attention to AAWAV'S Specs. Not to worry BadAzz. Both amps have been tested and vetted by myself AAWAV and HAZE. For lack of a better term they are BOTH Bad Azz amps!! Buy it brother!!
