Distribution Block ?
 

I'm having a hell of a time finding a wire kit that has everything I want to what I'm willing to spend. Basically, I want to run 4 AWG power wire to a distribution block (I wanted to keep everything 4 AWG) going to both amps but it seems every distribution block has (2) 8 AWG outputs, WHY IS THIS?

Anyway, I found this kit that has the main 4 AWG power wire, 4 AWG > 8 AWG power block but for some stupid f****** reason it has "9" AWG power and ground wire. If I am running 4 AWG to the power block and (2) 9 AWG coming out to both amps, don't I want to use a 4 AWG ground? Why the hell does this kit come with a 9 AWG ground?

The power block it comes with isn't even fused either...

Ideally I just want to run 4 AWG to a power block and (2) 4 AWG to both amps. Can someone suggest a kit or something... I've spent a week planning this install and I'm frustrated...

Please ignore previous rant. I found the answer I needed. I MUST use 4 AWG wire throughout. The 4 ch amp I will be adding later is 80A fused and the other is 40A.

I just need to know what I can use as a distro block that will accept 4 AWG in and (2) 4 AWG out. I can't find anything in these local shops...

just run two seperate fused lines from your battery or buy a 1/0 kit that splits to two 4ga lines

That is the answer I am looking for but there is no place around here that sells 1/0 unless I go to futureshop and plan to spend $200 which I don't have...

Any ideas where to get a single 1/0 power wire? I can pick up the other kit with the 4awg and use that...

Why not just buy something like this kit...

.....then buy your distro block seperate, you can buy a 1/0 distro block and have all the 4ga hookups you'll need on it.

I could but I like to have excess wire for when I connect the 4ch amp. Right now I am just gunna wire the mono and subs.

To break it down, I will have 2 amps 800W TOTAL RMS
Both amps combined max amperage is 120A (40 and 80 fuse)

I want to know if it will be OK to run 4 AWG power wire to d-block outputting 2x 8 AWG to both amps. Doing the calcuations this is JUST pushing the limit of amps per cable length/gauge. Obviously, it would be best to use 1/0 from battery to d-block and 2x 4 AWG but can I get away with 4 AWG > 8 AWG?

Thanks.

You will be fine with the 8ga, just keep it as short as you can.

Thanks for clarifying that. My last question (I swear) so 4 awg split at d-block with 8 awg to each amp so does this mean I ground both amps with 8 awg? or can I ground them with 4 since the main power wire is 4?

Thanks again. I've been reading forums and browsing every single car audio site for a week! Before this I knew NOTHING about this stuff. Installed my DEH-6900UB a few weeks ago, was surprised to hear how good it sounds on stock speakers alone, then the mission started to connect subs :)

8ga ground will suffice, just keep it short too. Always use the same gauge wire in and out of the amp.....yes you can install the 4ga ground but there's really no point.

This kit actually has 9 awg so I'll be using that. I don't know why it's 9 but it is! I'm going to keep it as short as possible. The block will be right next to my sub amp so 1' wire there and 2' to the second amp.

Thanks for the help!

I just realized the kit comes with an unfused d-block. Would it really be necessary to have a fused one with the 9awg being such short lengths? If so, could I use 1/2 the amp fuses as in the amps? ie. amp1=40a could I use a 20a fuse since the block is 1' away from the amp?

Sorry for all the ?'s but no other place to turn but the net.

No need to fuse the amp at the dist block, a single fuse within 18" of the battery is all you need.

You can use a Capacitor 1 farad at least, and use the positive terminal like distribution to 3 points or more depends on your ability. Even you can use 8 gauge from there to your amps.

I picked up some "supplies" today. I have the 8ga now and some heavy duty monster RCA's. You saying run the main power 4ga to cap and split it off twice to 8ga? This eliminates using a d-block altogether?

exactly...even you can split with 4, or even 0...You can use a 0 gauge ring terminal, and put two 4...just solder it. If you have the rca monster Rca, ok, but I use to use the regular, even in competitions cars!!!!

I think I will go with using a 1F cap. I can get a GOOD deal on one and it will save me from getting a d-block later when I connect the 4ch amp.

Why don't I need to fuse from the cap > amp? What happens if a cap "goes bad" stops working, etc, do the amps just turn off?

Thanks for the tips!!

you could always use a 1 awg disytro block that spilits into 2 4 awg runs cuzz the 4 awg wire will clamp in the 1 awg spot easily:)

what about a distro block with multiple 4ga. inputs?? if he's got it all fused up at the battery, just put 1 - 4ga in and 2 - 4 ga out...the power is all intermingled anyway...
