I am running a modern radio (alpine cde-143bt) in my 66 mustang coupe. And yes of course I cut the dash. How did you go about wiring it? I'm running 2 6.5s(alpine type r) in the kick panels, 2 6x9s(alpine type r) in the package tray, a 12" subwoofer(alpine type r), a mono amp for the subwoofer(alpine mrv-m500), and a 4 channel amp(alpine mrv-f300) for the other speakers. Any pictures or advice will help a ton. Thank you.
