Head unit wired into stereo battery bank? Other stereo issues, please help.

I am working on wiring up my system on my boat which is the following

-2 exide deep cycle marine batteries
-JVC headunit
-1 Memphis 600w amp (sub amp)
-1 apline 4 channel (in boats)
-1 MB quart 4 channel (towers)

I am having all sorts of issues with my amps going into protect mode and now working on re-wiring everything and there is something weird going on with the head unit.

Wiring setup

-Power and ground wires from the batteries are wired into distribution blocks which are then wired into each amp with their own 8 or 4 gauge wire.

As far as the remote wires go, i was having some issues with the amps going into protect when the remote was wired into the head unit so i put them on a switch which is tapped into the battery power off on of the amps. With this it is all coming off the same battery power.

The head unit is also tapped into the power and ground terminals on one of the amps.

Now what is going on whenever i first turn on the head unit, then flip the switch to turn on the amps the head unit will instantly turn off and not come back on.

If anyone has a simple diagram or can explain the best way to wire in a multiple amp system on its own battery bank that would be awesome. I have wired up multiple stereos before in cars and have had no issues, but for some odd reason this stereo is throwing me for a complete loop and looking for any help possible.

Thanks in advance!
