I wired my amps directly to the battery. As in directly on the battery terminals, not through any bus bars nor switches. Separate fused connections running straight to the amps in the cabin.
You'll still be able to use the switch for its intended purpose - to isolate or combine the batteries. But if you wire directly to the battery you can't really turn the amps "off" without pulling the fuse. Pros/cons...
Wired mine the same way...No harm with that setup, signal wire from the head unit turns the amp off.I wired my amps directly to the battery. As in directly on the battery terminals, not through any bus bars nor switches. Separate fused connections running straight to the amps in the cabin.

I wired mine to the battery switch so the amp and stereo runs off the battery selected on the switch. I have two batteries that I alternate between, I don't use them has a starting or house, both are used as a starting and house if they are selected. I like to know that EVERYTHING is powered off (except the bilge pumps) when I turn the battery switch off.
At the same time, you need to make 100% sure, that head unit also shares the exact same terminations.
its been my practice to terminate audio amp's B- directly to the/a battery and the B+ to the output of the main battery switch. No ground BUS or switch/breaker panels, no helm BUS or fuse/beaker boxes, etc. This insures you are not overloading a supply circuit that may not have been designed with that amp's draw in mind. It insures the least chance of unwanted noise. It allows voltage to be removed from the amp when the boat is put away.
