Can hook up the convenience wire to the head unit and call it a day? Or, do I need to hook the red and black to the reverse circuit as well?

2003 Chevy Silverado, Cheap android head unit, 1500w amp with 2 12" subs, and a Sony xmsd400d amplifier for the door speakers.. Everything works and sounds great.

Right around the time I put the Sony amp in, I started blowing ignition fuses intermittently on start up.

It will start 20 or 30 times just fine, and then one day it will blow the 40a ignition fuse when I turn the key. I'll replace the fuse, turn the key again and it will usually blow the fuse again. Replace fuse, try again and it will be good for a couple weeks. Heading to lunch today (with a coworker of course) I blew a couple fuses, after lunch, I blew another fuse. I disconnected both amps from the battery and still blew 2 more fuses! Could it be the head unit? Could it be something else that coincidentally broke around time of install?
