Upgrading Stereo - Reviews Requested

[MLA]

So in the setup as shown, where would you add fuse or circuit breaker protection? Would it be on the 1/0 between the Blue Sea Switch and the + Distribution block, 150 amp? Also on the 6ga connection from the Blue Sea Switch to the Main House Buss, using the 50 amp circuit breaker installed currently?

I am redrawing the diagram with the HU and ZLD connected to a positive and ground strip. I'm adding a fuse between the distribution block and the positive strip. Any thoughts on fuse size for the HU and the ZLD?

Ron,

The circuit protection for the amps main B+ needs to be right the source. Within 18" is the norm.

Although the ZLD has an in-line fuse AT the ZLD, this fuse is there to protect the circuit if the ZLD itself has an internal short. It will to nothing to protect the 20ft of 14ga positive wire thats running around the bow of the boat from the battery to the helm where the ZLD is mounted.

So how does this look?

That looks good. Again, personally I wouldn't circumvent the functionality of the dual circuit switch related to the amplifier draw yet leave the switch intact relating to the alternator and starter feed circuit? How does the capacity and resistance of the switch become an issue as compared to the contacts in the ACR? All that defies logic. So I would go with it as you have it.

what is a blue sea ACR, and what does it do for you ?

An ACR (Auto Combining Relay) allows your house (stereo) battery bank and main starting battery bank to both receive a charge from the alternator while the engine is running. When the engine is off, it isolates, or disconnects, both banks from each other so your house/stereo loads only draw from the house battery bank. This is done automatically.

thanks for explanation in simple terms that i could understand.
