Alpine Halo 11 is the only one for me, integrated with a reverse cam, integrated with Alpine front and rear camera and ADAS (*ish) system. Paired with a FireTV without an iptv subscription that I didn't set up on it and an AA Wireless dongle from Kickstarter - but I think they are fully fledged now - absolutely genius device. Movies and TV for camping, Android Auto for nav and tunes, games console via the Xbox and Luna app and controller to keep the boy happy. Rolled in with the full DSP Apline under seat sub and the 8" door speaker and tweet set, full soundproof on the doors 2mm dodo.. cab arches and footwell planned next.
I agree with the above, though.. I will probably take out the pre-amp fed DSP amp on the sub and take the Halo post amp to the speakers instead, then get a Focal Impulse 4.320 dedicated to the alpine enclosure. The DSP ain't up to much to drive the lot. I remember the feeling I got with just the speakers changed and the Halo 11 coming in before the sub kit offloaded all amplification and messed it around. It will be better to have fully customisable levels on the head unit again, too.
