New system, more advise needed XD

[evoxbeck]

Alright, so I have been doing this for a few years. Just in the subwoofer installation area.. I have an MB Quart ONYX 1.1000D(1ohm stable 1000watts) pushing an Alpine Type-R(1000rms)... I have 4awg power and ground etc. I am about to upgrade to the brand new JVC Arsenal with the vari-color illumination on every button(160), before I install my Polk Audio PA660 4channel(75watt x 4ch).

I was wondering how exactly to wire a power and ground distribution block.. I understand the grounds simple(no fuse needed) plug and play ordeal.

I was going to run 0awg from the battery to the trunk then branch 2 or 4awg to my sub amp and 4 or 8awg to my 4channel. My question is within the fuse ordeal. My 4 channels 2x25fuses, mono block is 1x80 maxi fuse.

1.)Do I need to have the distribution block for power with a fuse?

2.)Do I need a inline fuse 12-18" from the battery accomodating the 130amps or fuses on the amps. Or should that inline be 250amp?

3.)Do I need an inline after the distribution block(between the branch off of the distribution to each amps)?

4.)If the distribution block has 130amp total fuse, am I good?

5.)I have found distribution blocks with, where you can have say 1x80 and 1x60 in it) is that dumb?

How many inline fuses are required within using a distribution block for two amps.

Should it go:

12-18" 0awg-inline fuse(130-150amp)-16' 0awg-power dist block- branch off to mono-4' 4awg-inline 80a-4' 4awg-amp & 4channel branch off: 4' 8awg-inline 50a-4' 8awg-amp?

I hope that isn't tooo confusing?

Thanks,

I have a link for you I'll post later.

Refer to the chart I attached.

Use the chart to determine the inline fuse between battery and distribution block.

If you haven't bought a distribution block yet, buy one that let's you put fuses in the slots that you're amps connect too, that will keep you from having in line fuses after the distribution block.

To determine the fuse amp sizes to place in the distribution block in the slots you're amps connect at, refer to the amp manual.

Or count the total amps on the fuses on your amplifiers, and put that fuse size in the slot on the block. I could be wrong on this part, maybe someone can confirm.

Sometimes you can keep things simple to avoid issues with dist blocks and extra fuses.

If wire runs are less than 14 feet, two 4 gauge lines with identical fuses for each line (100-120). Simple, if one of the amps demands 2 or 0 gauge then forget the two 4 gauge lines suggested

Assuming all of your equipment is internally fused, you're only fusing for the size of the wire, not the equipment. Don't use any larger than a 150 amp fuse if your main power run is 4 ga, for example. It's safer to use a smaller fuse. Any time you step down in wire size you should fuse for the smaller wire. This is a best practice for safety.

Sketch out your wiring on paper. It helps keep it straight in your mind.
