Beaver Marquis Bose Replacement
I am in the process of replacing the audio/video system in my new (to me) 1999 Beaver Marquis. I've taken out the Bose surround sound amp, and Lifestyle player, but can not find the Bose Acoustimass ...

Today the goal was to finish the radio install. The wiring harness from the old Bose was well marked and I was able to cut the harness off, then connect wire for wire to my new radio harness using 18-22 gauge butt connectors. The two 12V wires ran to the same source rather than to battery and one to ACC. The ground wire was clearly labeled as were illumination wires which would serve to decrease the radio lighting when the light are on. These 2 wires don't have a purpose with the BOSS radio I installed as it has the LED display.
After making the power connections I proceeded to wiring the 3 audio connections.
My plan involved connecting the Bose front R/L speakers to the amplified R/L front speaker outputs of the radio. Also to connect the rear Bose Wave Radio outputs (from the replaced Lifestyle 20) to the front pre-amp outputs of the new BOSS radio. The other Lifestyle 20 audio outputs were connected to the Rear Pre-amp outputs of the BOSS Radio. The Bose Wave output was easy as that cable was complete - I just tucked it back into the dash so that I could poke it through to the radio.
At the radio end the other connections were done using butt connectors 18-22 gauge, and the existing RED/WHITE connectors from the Lifestyle Audio outputs. These two cables are already routed up to the TV cabinet, but they are simply wire ends which had been connected to the amplifier. For the amplified radio outputs I butt connected them to the two speaker wire pairs to drive the existing Right and Left front Bose speakers. I dry connected these first just to what I guessed was the correct pair to drive the Left front Bose speaker. Having one speaker connected I could now test the radio which worked fine and I'd guessed right about the wiring so I butt joined the remaining wire and now I had an amplified Bose front speaker right and let. I went to the back of the RV, used the remote control for the Bose Wave Radio in the bedroom, selected the AUX setting and found that its connection was ok as well as I could now hear the front radio in the bedroom coming off the Bose Wave radio.
That left the connection from the pre-amp Rear speaker outputs. I already had a male end connector coming into the TV cabinet from my Vizio sound bar so I needed a female connector and then bare wires to butt connect to the wire pairs coming from the radio. Well, this female type of connection was part of the Remote Control audio output cable from the Lifestyle 20. I had disconnected that short cable and then cut the end off and separated it from the "remote control line", and now had a cable with female R/L audio connectors on the one end and 2 positive and 2 negative bared wires from having cutoff the connector which were the right and left audio channel wires that I could now butt connect to my two pre-amp wires coming from the radio.
I took note of the positive and negative and placed butt connectors on each of these 4 wires, then returned to the TV Cabinet and located the bare ends of that audio cable in the TV cabinet. Again I guessed as to which pair of wires was left and which was right and dry tested before making the final connections.
These 3 connections took care of the audio from the radio. I am still toying with running a video line to the TV cabinet, but I haven't quite worked that out yet. The video is a two wire connection as well and one wire was the remote turn on wire coming from the original radio and the other is a wire from the remote turn on (of the amplifier) from the Lifestyle.
After thoroughly checking the radio including the NAV system I pushed it into the double din chassis to lock it into place, and pushed the pins of the dash piece through the holes in the dash so that the dash piece fit properly into place. The only thing left was housekeeping so that the nuts were reattached to the dash pins to secure the dash. I also screwed the original backstrap to the back of the BOSS radio using a short screw I had that was left over from the HDTV mounting.
I had wondered where to run the NAV antenna but had read that you can often times just leave them under the dash, and I tried that, and it seems to work fine even though I was in a covered parking space at the storage lot. So, I'll just see how that works on the road. The Bluetooth Microphone and IPOD connectors I ran out into the area previously containing the Lifestyle and after tie wrapping the tremendous lengths of audio cable from the Lifestyle now being used to drive the Vizio and rear Bose Wave, I pushed those back into the empty space previously occupied by the Lifestyle.
Now, if I want to use the radio but not the surround system, I fade the radio to the front or simply turn off the Vizio sound bar. To run the radio on full surround stereo with bass woofer, I set the fader to completely REAR position. If I want to listen to a CD in the bedroom, I use the front fader and set the Bose Wave to AUX input.
Now I have to finish cleaning up the cables in the TV cabinet and add my two shelves - one having the Dish VIP-222k receiver and the other holding the Vizio sub-woofer.
One last finishing touch was to place my custom bezel over the radio for the completed look. I'll have to use a couple screws I suppose to hold it in place but friction is doing it for now.
