So I'm wiring up a 450 watt Kenwood amp under a false floor to run a RF Punch P3 DVC. I'm going to run a cooling fan on it with some slots in the floor to allow airflow. I've read not to just splice the remote wire as this can cause problems. So, I would run the remote wire to a Bosche relay, then from the relay to a bus bar, correct? http://www.thehotrodcompany.com/shopnow/show_item.asp?product_id=426671 The reason I was thinking of doing it this way was incase I wanted to add another amp or if more fans were needed. Please tell me if this would work or if I'm fully off course here.
