What an excellent post and install, well done and many thanks for sharing.
This is something I've been planning on doing starting probably around Xmas. Initially my thinking was to add a Pioneer Avic unit, though keep swaying between this and a iPad mini install using the GT delete fascia. The Pioneer Avics are great though and yours installed looks perfect! nice, neat & tidy.
Amp wise, again you're a man after my own heart. The Alpine PDX amps are cracking, great size, clean power and literally no floor noise. On this one though it's a tough call between the PDX-V and the new Alpine PDP-8000. Whilst the PDP doesn't quite have the power output of the V, the integrated processor, optical input and WiFi make it quite a unique starting point, especially on a staged approach working nicely with a Gen 2's non Bose PCM3 with a view to either leaving the PCM3 installed, going down the Pioneer Avic route as you have or shooting for an IPad mini install. Decisions decisions.
Love the sub as well. Weight would be slight concern but you have clearly considered this as you mention keeping the design small and thickness down. I pondered over a Bose unit based purely on weight, upgrading the drive units as others have done, but I'm not sure if it's worth the effort and the route you have taken will be vastly superior I'm sure.
I think I'll be bouncing back and forth with your post for ideas and inspiration over the coming months. Great timing and thanks again for sharing. :worship: :worship:
