I know there are a lot of fans of the Arc Moto 600.4 I am not one of them. I agree you need more power for that setup, but i would choose a different amp than the Arc. Something like a Focal FDP Sport, or Soundigital 1200.4 or even 2 micro amps like the Diamond Micro or Ground Zero GZRA Micro 4. Another option would be a Massive BLX 48.
If you are using the stock HU than you would see a benefit of a DSP, especially if you use the Soundigital or a Biketronics amp. If you don't you will need a BT 355 line leveler.
