If you pull the amp fuse (fuse 23 in some models), the amp is powered down.
Not questioning your thought process above because I have a respect for your knowledge regarding electrical circuitry in the Crossfire, but the wiring diagram for the stereo system states that the Fuse 23 leg feeding the amplifier is HOT only during ON/RUN, and START. Looks to me that the Fuse 8 leg, which is a direct feed from the battery to the radio, does provide power back to the amplifier via terminal 4. And there looks like a hot connection between circuits Fuse #8 & Fuse #23 via terminal connections 4 & 9 on the amplifier. Several cross-feeds going on if I read the wiring diagram correctly. Is that the case/ Comments?
