I installed my subs and 2nd amp this past weekend, everything is peachy except when I shut the truck off. Usually the system stayed on until one of the doors was opened, but now it shuts down immediately and says the message across the info screen on the radio.

Door speaker amp is an Alpine PDX-F6 and the subs amp is a Memphis PR1000.1. So yes, It's pulling some decent power from the overall system. Each amp is being run off it's own 4 Gauge Power and ground wires.

Anyone else run into this problem? Solutions?
