One problem with that connector is it doesn't have a remote amp output, so although you can get an RCA signal out of the unit you have no way of turning the amp on with the stereo. You could get around this by wiring the remote input on the amp to some sort of switched +12V when you fit it, but it's not a great solution. I used a Line Output converter with a remote amp output to hook up an amp to my RNS-510 and the results are really impressive, but it is a bit of a fiddly job...
