17 Mojo Stereo Setup!

[rdlangston13]

Here is a make shift wiring diagram i mocked up of the power wire runs. The main power wires from the batteries to the switch to the distribution block with be 1/0 Gauge. Coming off of the block to the amps I am running 4 gauge. I am curious on the set up of the stock distribution block and if it will support my loads I will be using. Trying to decide what type of battery switch i want to go with as well. Plan is to run 4 sets of 12 gauge speaker wire to the tower for the Rev10s and 10 gauge to the sub, or will 12 gauge be sufficient for the sub as well? Also, what is the best way to connect two 12 gauge wires to one terminal of the SD2?

Why are you running that many grounds back to the GC battery, why not use your ground distribution block. I see the same thing on your relay, unless you're trying to bypass the switch altogether.
Also I would think tying your cranking battery ground into your audio batteries is asking for noise. Isolation...

I run power from the hu and 420 to the distro block that powers the amps. Same for ground.

This eliminates a ton of connections on the cramped post of the battery switch.

I'm planning on grounding the batteries together so when the switch is the combined/both position the alternator will provide juice for the stereo so I won't be running the stereo solely off of batteries for a whole weekend.

On the distribution block, what would I need that has ports small enough for a remote turn on relay and at the same time
Large enough for amps? Or should I run a small distribution block for the small current items off of a port from large distribution block?

I use 2 of these. 1 each for +/-

Blue Sea Systems 10 Gang Common 150A Busbar with Cover https://www.amazon.com/dp/B0091VHLW4..._PB.bzbDZSYBTS

And I expect someone to say something about the alternator charging.

What do you want me to say?

Any suggestions on a fused distribution block that has 4 gauge outs as well as 18??

Ignore the busbar amperage ratings and do not substitute a slight busbar for a heavy power distribution block. When using heavy gauge supply cables, I wouldn't use any junction with smaller than 5/16" posts. I also don't believe in stacking large and small gauge terminations on the same posts. When using posts as distribution, I would limit stacked terminations to (3).
David, Odin has a very simple, all-encompassing, and uncomplicated distribution scheme. You might run your final version past him.

Factory distri will support everything if re-wiring the mains to 1/0, Distri blocks are "thicker". Sub wire gauge depends on length of run but I like 10 gauge if it's at helm and amps in observers for a XXX. All others I do 12 gauge.. Parallel inside the enclosure for less wire at the amplifier.

Well not running a xxx sub but I figure I may as well run 10 now then if I ever upgrade I won't need to rerun any wires.
