No, the halo is moveable, not removable and is suited to the 1.5 but not the 2.0/2.5. I stuck with a single DIN as I just wanted a stereo with multiple media playback. I’m old so I have a huge collection of Kef speakers. Right now I have uniQ 130’s in front and 110/19’s rear but at some point I’ll try putting the UniQ160 up front or swapping the components to the front and adding some aura bass shakers. I stick to the class D amps which is totally new to me but I have a concern of pulling to much power from the APS so I’m still finding a balance and having a fairly steep high pass cut off presently at 80Hz to protect the speaker more than power requirements. The bass shakers I will see if I can get them under the seat but I’ll want to epoxy some ply to the floor and I don’t know if I’ll have the clearance, but I used them before and where there is no room I think I they work well. Again never with class D amps so I also worry about overheating. The fit nicely in the passenger footwell so the cabling is super simple. I don’t want to cut anything until I commit to fitting the components up front. Once that’s done there’s no turning back and my hearing is not what it used to be to warrant that much work and never ending playing around, it’s taken 6 months to get my simple home hifi set up after moving and a car is infinitely more complex.
I have a Mercedes proclip that happens to fit on my dash without falling off even with very spirited driving on rough roads. Paired to a baseus wireless charge mount, I put it there as a temporary holder while doing some work and it’s stayed there. I also have an old iPod Classic (15 years old) for storage, an iPod touch (smashed screen and dead battery in case someone thinks I’m super rich, I just didn’t want to throw it away) to leave in the car and stream Apple Music and my phone with the huge screen does GPS duty when needed. Mostly it’s just charging my phone. I felt I wanted audio rather than visual and I have comprehensive playlists that Siri takes care of for me. When working with a clipped medium I still prefer using a CD but the car is not big enough and my home Collection is never going to the car. I simply consciously decided I would be happy with a single DIN in my car, the obvious choice would be double DIN conversion but then where do you stop?
