The head is the standard cd casset, My nav should be here next week (still gotta find the antenna for it at a reasonable price). It should not matter if you unit is the lux or premium Bose system for the line level converter. It puts only a minimum load on the lines. As for the maxxsonics mx-4 yes I am familure with it and it will work fine.
As for the sub. May I once again recomend the AudioBahn tube. I payed $107 for it on ebay using but it now and am utterly impressed with its quality (expecially for the price).It also has a built in 100 watt amp that is solid. Additionally If you didnt have a line level converter like the maxxsonics mx-4, it comes with high level inputs. Big Bonous ALL NEEDED WIRING INCLUDED! yes it comes with 10 gage wiring and RCAs.
