Simplifying electrics and improving safety

G'day team,

In the process of replacing components that are showing age by upgrading.
I've ordered the Big Seven kit off Jeep Cables and the Aux power kit. I've also ordered the HKG fuse and intend to replace the battery with a 24f AGM battery.

I currently have the following accessories:
Aftermarket Amp for sub with JBL amp driving speakers - Aftermarket amp on is powered from an accessorie fuse as the JBL takes the one from the head unit.

Rear camera- powered off head unit.

Fore and aft led lights in bumper- relay and after market switch in cabin.

Wolfbox dashcam - add a fuse in cab for both power sources

I am going to install:
Fwd camera- powered off head unit
Raptor lights
Upgraded headlight wiring harness off the megathread

Can I just run all of these off the blue sea or am I missing something? I assume the amp 4 gauge will stay on the batter but the rest of the power can be drawn from the fuse block?

Any recommendations for a switch if I need one?

Thanks team
