One more quick question. There is a small screw inbetween each pair of RCA connectors on the amp. And there is a small wire inbetween the two RCA cables themselves. Should this be another ground wire? There is a place to connect this ground to the empeg at connectors 16 & 19.

Why would I need to run a ground wire inbetween the RCA cables, should I connect this? I don't see why not.

-Thanks
