Need recommendations on replacing a Bose Lifestyle.

[CleanSound]

Ok, my father in-law has a 20 year old Bose Lifestyle 38. The speakers and sub is custom in-wall and in-ceiling installed when he had his home built, 20 years ago. The Bose speakers are powered by the subwoofer as the subwoofer has a multi-channel amp built in; the multi-channel signal to the subwoofer uses a Bose proprietary 9-Pin DIN plug.

Anyway, long story short, the Bose is no longer working, we believe the issue is with the head unit. The in-ceiling and in-wall sub and speakers are still functional.

First question: Since the sub and speakers are in-wall and in-ceiling, his first choice is to salvage that custom install. Anyone know of a Bose 9-pin DIN to RCA converter, so that he can get an AVP to replace that Bose head unit?

Second question: If the in-wall and in-ceiling sub and speakers cannot be salvage, we just have to rip it out (and patch up the holes). But he would still want a new surround system. What options are there today equivalent to a Bose Lifestyle? It can be in-wall/in-ceiling or on-wall/on-ceiling.

Read Spades45 first 3 or 4 posts. Not sure if this is the same system but it's the nine pin. The Sub might need replacing but the other speakers might work.

Purchased a standard subwoofer and AV receiver, hacked off the RCA plugs on the Bose speakers and connected them to the receiver and everything works perfectly! Plus I made $100 selling the old Bose sub and receiver on craigslist.

I can confirm there is no weird distortion or adverse effects. Sound quality is improved due to the new sub. Replacing the receiver saved me a lot of headache thanks to HDMI among other things.

Sounds like they wired the speakers directly to a receiver and bypass the amp in the sub. I want to keep the sub because it's part of the custom install.
