So, just to be clear , it looks like your amp/xover power comes from the regular 12 battery not the main car's battery like Travis (guy who hook his audio equipment via the "penthouse" 12v under the seat). I am assuming that if you were to do that (use the penthouse main battery) then you need to create a relay/resistor combo? Otherwise, the easiest way (which I like easy) for power is directly connecting to the 12v regular battery, correct (do a proper shutdown first before connecting)? Thank you.I learned by lesson too. Always do the proper shut down! Those warnings freaked me out the first time around!
