I recently bought "Acoustimass® 5.1 speaker system with Pioneer VSX-822K receiver" from Costco. My house has surround sound pre-wiring. I am not sure how to connect acoustimass sub-woofer to the pioneer receiver.

Sub-woofer connection is in the back of the room. I opened the wallplate and it has one thick black wire (haven't stripped it yet to see what color wires are there in that). I am assuming that I can use an RCA / co-axial connector to connect it to my sub-woofer. But the bose sub-woofer has multi pin audio input jack. How do I connect the pre-wire that I have in my house to the sub woofer?

Also, the manual shows that I need to connect the speakers and the receiver to the sub-woofer. But I was thinking that I need to connect both speakers and sub-woofer to the receiver. I found in some other forum that, usually it is the case of sub-woofer and speakers connecting to receiver, but in case of base it is other way. Is it true?

I am a total newbie and any help is really appreciated.

Yes, I did. Before I bought this speaker and receiver system. I was aware of how the connections will be. But when I saw multi pin audio input jack on the back of base woofer, I searched online if there is an adapter for RCA to multipin audio jack and I didn't find any. So thought of asking here, if anyone has similar system and if so how was it setup. If I had to connect subwoofer directly to receiver, then i won't have any issues, but I want to use the pre-wiring and how sure how to connect that pre-wiring to subwoofer (multipin audio jack)

If you want to use the prewiring for the subwoofer that is located at the back of the room then the prewire needs to be a RCA connection that will connect to the RCA input on the back of the subwoofer. You mentioned the prewire cable was a thick black cable, I'm assuming this is a coax cable that will need a RCA end installed.

Mike,

Thanks for the reply. But back of my Bose sub woofer doesn't have an RCA input/output. Instead it has a multipin audio input.

Refer to attachment of how the connection was given in the bose manual. With my existing pre-wiring, I am not sure if I can use this. I have to either connect as shown in the image and ignore my pre-wiring OR change the system. Correct me if I am wrong and if there are any other options.
