Hi lunchboxGTI - Thanks for your information, are you referring to wiring up a harness cable that plugs into the back of the RNS510 that takes the same connections as the speaker outputs, and then changing the RNS510 from speaker to amp mode?

Hi Rambo - Thanks - sounds like neat upgrade. How did you splice the Addison into the Columbus? Just via the front speaker outputs? How is the sound quality? Figure if your running your fronts then sound quality must be fantastic? I have also been hesitant with high pass inputs buts I guess if you have a quality controller, then that makes all the difference? I know some amps have high level inputs but do they not do as good of a job? I'm thinking for a sub, sounds quality via high pass into amp might be ok??

Also, with powering your equipment, how did you splice into power and was there any issues with other car electronics having power issues? I read that the new Octy is pretty sensitive to power so didnt appear as simple as finding a 12v feed or connecting new amp fuse to the battery?
