All that hooks up to the ARC amp from the HK unit are the speaker wires that are on the speakers, nothing else. The ARC amp comes with a little white plug that is where you connect your exsisting speaker wires. new wire to the speakers comes off the set screw connectors on the amp. you need to make all this up (power wire ground wire speaker wire power on wire fuse holder) or buy a amp wire kit off ebay or some place like that.

 

I don't have that white plug. Bought the arc wiring kit but don't have the plug. If anyone has it because they used the rca inputs I would love to work out a trade/purchase of the plug.

 

I would message firecap501 about the plug....
