Replacing The Bose System
That said, IDK about the earlier years but I can tell you for a 91, it is simple or not depending on what you want to do. If all I need is a radio, the choices are plenty. Budget? That is HUGE. What skills do you bring to the table? How willing are you to play circus contortionist? Those all factor in. Also what is the goal of this piece of electronics? Are you going to be a audiophile? If so, I don't know if you will be happy with the acoustics so it might be money wasted. OTOH, if all you want is a radio making sound, that's easy.
In my 91, I don't care for excellent sound so basically, it doesn't have to be too expensive. Bought 2 front enclosures and 2 rear. Bought the speaker bracket for the Non-Bose and simply outfitted speakers as though they were Non-Bose. Had Best Buy run wire for it from the head unit to the rear and front speakers. Leave an extra foot of wire and I will make the fine connections. Head unit? any single din works since I am not that picky on having perfect sound. Got the right harness from Crutchfield and life was good.
