Is this wiring kit any good?
Audioline kit - AL002 2 Amplifier Wiring Kit, 4 Gauge | Car Sound, Car Accessories : JB HI-FI
Im going to install my system soon and didn't know whether the brand/quality of the wiring mattered a huge deal or not.
I think this brands nothing special but its got most of what i will need to run a 2 amp system and its a good price.
Already spend a bit on the system so really dont wanna spend too much more on wiring.
cheers for any info.
That dent guy
What amps are they? A single 4awg power wire won't be enough for a fairly big 2 amp system.
You are right though, wiring brands doesn't matter as much as some would have you believe

Why not just spend a little extra and buy two seperate 4 awg wiring kits?
You said you allready spent a bit so far, so why skimp now? You don't have to go nuts and buy silly brand name kits that don't make stuff all difference as mentioned above, but atleast do it properly.
Dont go tight on cables.
Use thick power and earth cables. You can also wire up your own RCAs. Go to jaycar or Waggner to buy your RCAs if you are putting the ends on.
get quality RCAs.
Response AA0426 4 x 100wrms
Alpine mrp-m500 mono 1x 500wrms. someone recommended me to split the 4 into two 8's for both amps.
Yeah considered going to jaycar, but saw this pack and as it had what someone recommended me i thought id have a look.
And I've already spend a bit of money so i meant i don't wanna spend too much more as money doesn't grow on trees
Should i buy a 2g and split it into 2 4ga's?
Who would you want to split them, as apposed to two seperate runs?
I would run 2gauge to both amps.
In my car i am running pioneer amp 2x 125rms for my splits 2 gauge power and earth.
Mono block 0gauge power and earth.
Not quite sure what you mean, but i was told running a 6m 4awg power cable to a distro block, then 2 short 8awg cabled coming from the distro block, one to each amp
Just run 2 seperate 4 awg cables, don't worry about who ever told you to split a 4 into 8 awg, that's just silly.
Why spend money on a distro block so that you can just run a smaller gauge cable?

4ga is fine for upto 1000w, which this system is under. that kit will be fine..
Power is measured in DECIBEL

I wouldn't say it's overkill, but it's not nessacary to ensure adequte current draw.
Yeah thatwas one of my main options, 13m of 4awg from jaycar would cost 125, plus rcas, maybe 50, which is ok but wouldnt want to spend too much more than that.
Haha, One answer that will persuade me to buy it

lol, well said
Wire's resistance is also relative to its length, so try keep the 8ga runs short. I have ran a few systems similar and perform fine, it doesnt give much headroom for say future upgrades however.Yeah thatwas one of my main options, 13m of 4awg from jaycar would cost 125, plus rcas, maybe 50, which is ok but wouldnt want to spend too much more than that.

You want the biggest power cable going to each amp that their terminals will handle.
Chances are those amps will both take 4g max (guessing here), so you will want either 2 runs of 4g, or a run of 2g split into 2 4g.

Yeah i was only planning to run the 8g the shortest possible for less loss. depending where i mount the amps it could only be like 25cm or so of 8g.
Does anyone know approx how much 2awg is per meter? Jaycar online has 4awg at $8.90, couldnt find 2 though.
If i did run a 2awg into 4awg's, it would probably cost the same as 2 4awg cables
Connection create resistance. Its better to run separate power wires to each amp.
As an auto-elec i have seen this lots of times. Eg starter motor power cable/alternator power cable.
less connections the better.
Yeah makes sense.
Though i got offered a 2awg power cable pretty cheap so i think il just use that then split with 2 4awg's to the amps. Should be more than adequate i think, and saves me some cash so im happy!
2 into 4 awg will be fine.
Sometimes it can be difficult to find 2 awg cable, a lot of places go from 4 awg, straight to 0 awg.
Yeah well a member on here told me he'd give a roll to me for $50 that should be the right length (will check up on that obviously) but that sounds cheap for what it would be in stores as 6m of 4awg is bout $54
For once people are actually recommending that people go way overboard on wiring rather than the exact opposite.
4awg split into 2 short runs of 8awg will be fine for such a small system, but will leave very little room for future upgrades.
Pretty much everything that's been said is true, but exaggerated. Yes, more connections=more resistance, but in the real world there will be NO noticeable difference. Yes, thicker power/ground wire would be better, but in the real world there will be NO noticeable difference between 4awg main run and 2awg main run in a small system.
$129 for an Audioline 4awg kit is a rip off. With the strong aussie dollar at the moment you would be crazy to spend $129 on Audioline shit when you could get a KnuConcepts 0gauge kit for almost the same price. Thicker, so it should keep the overkill brigade here happy, almost the exact same price once you factor in postage and far better quality wiring/fittings. Once you've seen 0awg flex the way this does you won't want to work with anything else.
0 GAUGE DUAL AMP POWER KIT
Captain Kermit - It does not matter the size of the system, it comes down to the amount of current the amplifiers will draw. It's always a good idea to factor in small voltage drops aswell. You can't simply base everything on 13.8 V.
Have a read of the table - WIRE Maybe not the best link for point of reference, but it's one of the simplest one's i have found to show other people.
Also, it does not matter whether the runs of 8 awg are 30 cm, or 10 ft each, the fact is you will be drawing current at some point, through 8 awg wire.
Well for the record i dont plan to do any future upgrades, not in this car anyway and not for a while if any so yeah.
So for a basic reference, that wiring kit, or any that splits 4ga to 8ga would be too small for my system (mentioned above).
cheers
There is a calculator on the site you linked that shows shorter runs of cabling can handle more current while sustaining less voltage drop than the same gauge cable over a longer length. Thank you for rendering your own post pointless.
I sustain my argument that 4gauge wiring run the length of the car, and then split using a fused distribution block into 2 short 8gauge runs will be sufficient. I also sustain my argument that you would be better off buying from the US and getting bigger, better wiring for the same price.
Alpines website and Jaycar's specifications also support my view, and considering they are the manufacturers of the products being used they can probably be trusted.
I'm currently installing 2 DD9915's and a 6,500wRMS monoblock into my car using 3 batteries (Optima D34 in the engine bay and 2 Absorbed Power 55AH batts in the boot) and a shitload of 0gauge wiring. I do not need to be schooled on current draw and voltage loss.
Also, JAKE-26, Generally buying wiring outside of a kit is a bit of a rip off, unless it's the only thing you need. That 2awg wiring may be cheap, but once you buy fuse holders, distribution blocks, ring/fork terminals it will likely add up to more than just buying a kit in the first place.
