I am trying to do my first (on my own) stereo project and I have a few questions. I had a company do the orginal install wich included adding an amp and a vsr relay. It looks like they wired the amp to the vsr relay should I do the same with the second? also they have the first amp grounded to a large screw they installed on the amp rack? should I ground it to the same point? some info I got off the boards says to use a different ground point but Im not sure what would be sufficent? any info would be great thanks

AFAIK, you need to use the same ground point, or at least at least be connected to the same ground. Not sure what a VSR relay is, but one thing to make sure is that the existing wiring is sufficient to handle the load of both amps.

over kill you can run the 2ga to a distribution block then 4ga to both amps
