Need help on power management!

[MR FIX IT]

Thanks for reading. I am currently install a budget system and wondering what gauge wire to go with? Can I use one power off battery and use a terminal block to power the amps? Using a Cadence 1000.4 for the doors, dash and 2 Alpine mrp-500 for the subs. It is going in a 2011 Toyota Sienna. Please, all suggestions are greatly appreciated!!!!!!!

I'd suggest 1/0 to a distro block and #4 to the amps, you could get away with CCA wire if you want to save a buck.

Thanks. Should I just fuse the 1/0 or do the 3 amp wires?
