As a side note I also took my Bose stereo system out, but kept the speakers. I put in a cheap Plye AM/FM CD/DVD player with bluetooth. The kind that was made for RV's or Travel Trailers. I thinned out a bunch of the wires that the Bose system used and got rid of the troublesome Bose Amp, 5 CD player, and the VCR was already gone.
Some people online indicated that the speakers would not preform well, but to my ear it sounds great, others ears also. In less space and with simpler connections to a front Roku TV, I can play music through the Bose speakers, play a dvd to the TV, play the TV through surround sound to the Bose Speakers, or play a CD through everything.
I am sure the bose system was really nice, but it is old technology. We rarely sit around in the RV and listen to music, but we will watch the TV in the evenings. Being able to play a DVD is nice if we can not stream something, so we keep a couple stored away.
Hope this is somehow helpful. Feel free to ask me questions since I also have a 98 Patriot and I have learned a lot from much help here.
