How long is a piece of string? If it is just for a set of speakers, and you have no plans for anything bigger, 8 guage is probably ok. If you plan yo go to subs, 4 guages is you best bet, install once keep happy. you will need to run rcas from the head unit and a trigger wire. A fuse holder is the same weather it is 4 or 8 guage, so its just a matter of if you want to fork out for the bigger wire. In a 33 is is quite easy because you only have a matter of metres to get to the battery. A metre tops is probably all you will need. Remember you will need speaker wire to get back to you fronts as well. If you are doing it yourself, $50 - $60 as a pretty much top guide, depending on where you mount the amp. if you get it done pro, you could be looking at over $120 mark, if they wire speakers and all for you. This method usually leads to a longer life span due to less stress :D But if u have a little knowledge, this job will be quite easy.

if u dont do it urself, go to a proper pro

ie. not JB , strathfield or autobarn

i had my first amp install done by strathfield, i gave them good wires etc. they used shitty wires cos they couldnt fit it and i only knew what happend 1 year later cos i had no idea about car audio then. (they used 4GA from the battery like i gave them, then as soon as they got under the carpets, used 16GA to the amp, yes 16GA..not 8GA, no dist block or anything)

i ended up ripping everything out, doing it properly, which u will too later down the track im 99% sure

We're getting a tad carried away here. Running a single Alpine amp is not going to require 2AWG cable.

As for the cable itself, much like everything else, you'll pay for quality. Realistically for wiring an amp up, including the speakers etc will set you back between $130-$200 for brands like Stinger and Phoenix Gold and between $250-$330 for brands like Streetwires.

JR, you asked where you can get 2AWG from? I can get it for you from any of the above mentioned brands. I use 1/0AWG in my own S15. :D

2gu wire is not rare if u are in the electronics field, the thickeir the wire the more power that the amp can suck out, prehapes 2gu on this set up is to much , bit still i would recommend it, i have 2 gu running my kicker Amp.

Also what is equaly import is the wire running from the amp to the speakers. seen so many people buy good quilty wire to the amp from the battery, but have thin wire running to the speakers.

i paid $30 dollars a meter for my wire from the amp to my subs from stinger.

use the calculator on www.caraudioaustralia.com

if ur feeding 1000rms over 5 metres, ur gonna want more than 4Ga.

otherwise ur probably not getting the full potential of ur amp.

go to www.caraudioaustralia.com then tutorials and have a look if u dont beleive me

Hey guys

Even thowe im new to this skylineaustralia forum. i still know my fair share of car audio knowledge. First of all find out what amp rating fuse's are being used on the amp. What type of amp class is the amp? mono block ect ect ?. Wonce you find out what the rating is of ya fuse, then you will be able to make a good choice on what gauge cable you should be running, and keep in mind if you are going to upgrade your system in the near future it may pay to spend that little bit more and go a bit thicker. The run of length of wire you use will also play a big part on the sive you will have to get. I am currently running 0 gauge and i everything is fine, but rember as soon as you go up size's in wire componet's like fuse holders, get expensive so just keep that in mind.

hope that helps :D

    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
    • It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
