Just sold our beloved 2014 to make room for a people mover to accommodate our latest family addition. Before selling, I took out the Bimmer Tech amp I bought and installed last year (April 2017). Installs in about 30 minutes thanks to plug-and-play harness and mounting bracket. Works like a charm and made a HUGE difference in the sound quality of our Hi-Fi sound system (option code 676). We loved the default DSP settings but you can customize it to create your own DSP profiles (see related threads on this forum). Amp is in pristine condition (see pic) and comes with everything you need for a truly audiophile experience.
Amp sells at Bavsound for $997 plus tax.
Asking $600, shipping to lower 48 states included.
Thanks, Phil
