After researching the options I ordered mine with the sound option 1. This gives you the blackbox headunit with main remote. And it is also integrated into the dash control panel. You also get 4 speakers.
The blackbox JBL unit gives you 3 pre-outs for front, rear and sub. I am adding 3 amps, 4 more cabin speakers, 2 subs and 4 tower speakers. Should sound good!!!
If you don't go with the Malibu blackbox then you have to mount a standard HU and remote.
