Thats the same system I have going in. Except I went with the 7873 head unit, and the rears are some JBL's I had lying around.
As for the Basslink, right now I just have mine strapped in because I haven't figured out where it will sound best and be out of the way. Even running off the stock head unit and strapped in, it adds great fill down low.
So, did you drill the floor in the rear to mount your basslink, or are you using wood, or what?
