Wiring Up A Harman/Kardon AVR5550

Hi All, I am new to this, so please be patient with me. I have purchased a Harman-Kardon AVR5550 with a Acoustimass 15 with no manual. I have the connecting cable between the two which has 6 pairs of red/Black (Ixos Plugs) and 1 Blue cable. I have download a manual, but it does not show me which set goes in what hole. Can anyone please help with advice or a diagram please.
Many Thanks for your time in reading this post.

Do you have all the bose speakers with the Acoustimass bass module?

Regardless I guess, all the Bose speakers plug into the Acoustimass module. Then the Acoustimass module connects to the speaker terminals and LFE output of the AVR. Respect the speaker position connections through from AVR to module and from module to speakers; e.g. front right to front right, center to center, etc.

Note the surround speakers connect to the surround channels of the AVR, not the back channels. Back is for 7.1 setup, this is 5.1 and would use the surround channels of the AVR.

Also, in this setup, in the AVR you set all the speakers to "large". The Acoustimass module handles the crossover for the speakers so you want to be sure full range signals go to the module. That's what the "large" speaker setting does.

Personally, I'd do a factory reset on the AVR and reconfigure from scratch to be sure it's set up properly.

Can you take a picture of the wire ends and post them?

So on the red portion of the cables it looks like I can see center written on one of them. That would be the center speaker cable and the red would be positive. Someone put banana plugs on them and you may have to unscrew the cover of the plug to read the rest.

The blue rca would go to the LFE or subwoofer out on the AVR.
