Upgraded from a 2014 F13... 2017 F06 Competition, since 2 weeks ago, detailing still required, but soundsystem upgrade was finished today: looks OEM with the exception of custom built sub enclosure for a 12” Focal FLAX, front+rear door and under seat woofers replaced with Focal components, Mosconi DSP/6-channel digital amp + Sountstream monoblock for the sub - smile is literally from ear to ear, will post some installation pics later.
