Mondo stereo make over, have some questions (battery and wiring)

[CFD3Captain]

I am adding (2) 6v batteries for my (new) stereo bank. Along with that, I am adding an Exile Javelin for my cabins and new sub and keeping one of my 800.4's for the towers. So I am basically re-wiring everything with a new dual switch (no ACR). I thought I had it all figured out then realized I am not sure. My question is ....do I need to have an inline fuse between the com post of the battery switch and the distribution block I am putting in (I was planning on the block being fused as well). I will be running new 1/0 cables with a single 1/0 in 4ga out distribution block. At first I was planning on just using the fused block with mANL fuses to match the fuses of the amps but I keep seeing others using an inline fuse on the 1/0 line from the battery switch to the block. Do i need both fused, or just one or the other. Other than that, I think I have it all figured out. Also, the Javelin has (3) 40a fuses and the 800.4 has (2) 30's, so I would be a total of one 180a fuse on the inline and a 120 and 60 on the distribution block?

With that said, anyone looking to switch to 6v golf cart batteries, Rural King (if you have one near you) sells their branded Exide battery for $79. It's not got quite the advertised spec of the Interstates, but it's damn close and Exide makes a great battery. At that price you can buy two for about $30 more than one Interstate or USbattery.

Thanks for the help. I thought I was going to be able to do this just on research and reading, but not so much.

No need to fuse the 1/0 inline wire.

No need to fuse the 1/0 inline wire.

Thanks, guess I didn't need to create a new thread for this. Maybe I will just make this my upgrade thread LOL

Absolutely need to have some form of trunk line circuit protection, unless the fused distro block is within 6" of the battery switch. This main circuit protection prevents that 1/0 trunk line from becoming a hot molten sparking red glowing fire starter when your landlubber brother-in-law tosses the anchor in there and shorts the ground and B+.

Ok....so a fuse on the "trunk" line going from the battery switch to the block. What size fuse.....the same as total of both amps or a little larger?

[MLA]

The sum of the amp fuses would be the max, but dont exceed the capacity of the cable.

Looking good!

Thanks! I am pretty happy with it thus far. I've never built an enclosure.....heck, I've never owned nor installed a sub in a vehicle before LOL. With that said, it ended up a tad larger than I was shooting for. I was shooting for 1.35 cubic foot and it ended up closer to 1.5. I didn't compensate for the thickness of the wood and the depth ended up being 11.5 instead of the 10 I wanted. Oh well, I am sure I will never no the difference

Made some pads for the feet from the hpde kick panel I removed and got some enamel on it! I need to get moving, the nice weather is coming (although there is a frost warning tonight LOL)

Working on the Amp rack....how critical is it running wires under the board for a cleaner look to keep power/ground wires from being next to RCA and speaker wires. It seems nearly impossible with what I am working with lol

Looking good man, subs are an addiction.

I got one in my car when I was a teen, had one in every car since, the house and the boat.
