In regards to the Arc system anything that does not use the Moto series speakers do have the very canned sound to them but the New MPAK 6 systems are amazing sounding and with the KS125.2 fan cooled amp it has no problems running 2 sets of speakers at a 2 ohm load. and with that set up the system would run probably $1000 installed from any retailer. We have also done installs using Hybrid Audio speakers which are probably the most amazing and natural sounding brand of car audio speakers on the market today.

 

Also those Alpine amps are very nice but just so people know any amps that are a class D design should not be installed on top of the radio like most amps are recommended for that install due to interference noise it can create through the radio. Most all amps that recommend being installed in the fairing are a class G/H design for that reason, obviously if you are installing a class D amp in the saddle bags there would be no issues with the noise.
