How to Hook Up Vandersteen 2W Subwoofer

Hi All,

I have a Vandersteen 2W sub that I plan to add to the system listed below--it's a hybrid stereo/HT setup. So far I've been using a powered sub that plugs into the Arcam's sub pre-out RCA jack. The 2W is an entirely different beast though and has the following connections:

regular speaker wire inputs (via banana plugs)
a WX-2 crossover with one set each of RCA ins/outs

The Arcam has tons of connections, including 3 RCAs for subs, but I'm not sure those will be helpful with the 2W. Here's a screenshot of all the Arcam's connections

Ideally I'd like to use the 2W sub for stereo (2.1) and HT (5.1) but I realize that may be impossible. At the least I'd like to use it for HT via the Arcam. Here's my setup. I would very much appreciate any specific advice on:

1. how to connect the 2W and its crossover.
2. which wire/interconnects to use

I have read all the manuals and can't make complete sense out of how they apply to my exact setup. THANKS very much!

Vandersteen 2ceSig IIs (mains; bi-amp/bi-wire capable)
Vandersteen VSM-1 (surrounds)
Vandersteen VCC-1 (center)
Vandersteen 2W (the sub I'm adding now)

Cary SLP-05 (for stereo pre): the Cinema In RCAs go to the Pre Outs on the Arcam

Adcom GFA-555 (for stereo amp): the mains go into the inputs on this; the RCA outputs go into the inputs on the SLP-05

Arcam AVR-600 (for HT/surround): powers the VSMs and VCC-1 surrounds (and I think will power the 2W)
