Sweetness on the install - nice job!
I would agree that Focal makes DAYUM nice stuff but SHESSH to you pay for it! I had Hertz in my 2010 and will be using them in the 2011 (HCx165 in lowers, HCx130 in rear pods) and will be going with the Mille MLK-165 separates for the fairing. Still laying out what I am going to do for the juice - looking at the JL Audio M400/4 but I'd like to keep everything in the fairing. Could be a challenge mounting that amp in the space available.
I'm gonna send my stock HU out to Tony at Iron Cross and have him do the low-level conversion (RCA outs) as well as add the mini-plug for Nav. According to him, it has no effect on the rear line-level (speaker) outputs on connector 28A, so it provides more options. I have also been toying with getting another stock SESG amp and bolting it next to the existing. Ipod module gets moved to wherever convenient. Hook the additional amp to the rear speaker outs from 28A (the 35-pin connector) then run the lowers and the rear pods from that amp. Still debating as the output from the stock amp would suffer greatly if you believe that the 100w/ch is based on a 1-ohm load.
Anyway ... again a sweet and neat install. Might be interested in taking your stock amp off your hands (depending on my direction) if you want to get rid of it.
