[Spider77]

Wire what up?

Wire what up?

Well i need to wire up the power leads and remote leads but have no idea how to wire them from the battery/headunit to the boot

[D-Man]

no but i need the 4 gauge to be wired up to the battery to lead to my boot where my amp is waiting right ? And i also need to know how to get the remote wire from the back of my headunit to my boot where again my amp is waiting ..Any ideas?

[Spider77]

Wow, a 4 gauge remote wire would be insane! SO you pretty much need to run your power (4gauge wire) from the battery to the correct terminal, and the same with the remote (ACC) wire? But dont know how to do it, or where to run it? What do you mean by boot?

Thats correct about the wires. I dont know how to run them through the car..does anyone have a guide i could use?

Boot = The thing ppl put their subwoofers/amp/shopping in. Usually located at the rear of the car

[goferris]

the boot is what us americans call the trunk of the car. I thought that there was something in the stickies about an amp install but I couldn't really find anything. I think most people run it through the firewall by either drilling a hole then using a grommet or just running it through the big bundle of wires going through there anyways. then they will run the power on one side of the car under the door sills and the output cables on the opposite side to avoid interference. You could always just pull up the carpet and run it that way as well.

Here's a link to the sticky on how to relocate the battery to the trunk/boot you could follow as well.

just take out the amp for the speakers...


go to crutchfield.com they have everything!!!

I could do this but I still wouldnt know how to get the remote wire to my trunk?

[D-Man]

Run a wire from your head units ACC (red usualy) thru a toggle on your dash and then run it under the carpet/back seats to the trunk/ "boot"

lol, the Boot

Sorry, i've never heard it referred to a boot before, but it does make sense. lol.

My remote lead is blue ..what do you mean via a toggle? im assuming the dash and centre console come off easily?

[D-Man]

A toggle switch, so that you maintain manuel control over you amp. And yeah, it all comes off pretty easy. Just drop that panel under you steering wheel.

I believe its a total of 4 philips and 4 10mm bolts, and 2 "clips" that just click in and out of place. Easy easy.

And the blue wire off of a head-unit is normally to a power antenna, witch will not give you the power to turn on your amp. Just FYI.

thanks for the advice..il try that tonight

Also to get the power cable from my battery to my "trunk" im going to have to remove the glove box right?

[D-Man]

I didn't. I ran threw a hole in the driver side fire wall. Right next to the steering column.

EDIT: oh nevermind, you're UK, you cab is mirrored. My fault.

IDK if you'll have to remove it or not. You'll have to ask some UK guys.

Thank you for your help so far ..il let you guys know how i get on tonight

[Spider77]

I think im going to refer to my trunk as a boot from now on, just to confuse people stateside.

[sanjuk]

So i took my glovebox off..


No sign of a hole for the power lead


Engine


found this hole on the top left of the engine..wire went in but had no idea where it went to

Anyone got any ideas..i dont really want to pay £100 to get this done at my local audio place:(

[D-Man]

Dude, you realy just gotta figure it out. That's EXACALY what a shop is going to do, they'll just figure it out

now if you want to deal with the hassle, then from your battary, you can follow some black lines into the fender, (remove the fender) and run them back into the cab. This is a massive PITA, but if you cant figure out anything else, it's pretty sure-fire. (it'll just take a while )

But i reccomend getting under that glove box, and reaching for that wire. It's where mine is wired thru. Right on the firewall, it's the best place to run it IMO. But IDK if you gotta drop the glove box or what, you'll have to figure that out on your own. Just remember where all your screws go.

whats this firewall you talk about? and what is a fender?

im such a noob:(

Firewall is that big wall between your engine bay, and you. otherwise, if it wasn't there, you'd put your feet on the engine and burn them Do you see the wall?

Fender is.... the White part

There is nothing wrong with being new, it just means that you have a bit of catching up to do.

[sanjuk]

ooo I tried it to put it through the the gap from underneath the bonnet via there and the lead was going somewhere compeltley differant? I couldnt even see it through the opening:(...il have to carry on tyring tomorrow when I have some light..thanks so much for your help so far!

[GriffGirl]

When you are facing the front of your car with the hood (bonnet, right?) up, on the right side of the firewall you will see a black rubber grommet with a wiring harness going through it. (I can see it in one of the photos you posted) Run your amp power cable through that grommet - you'll have to kind of wiggle it in there, but once you get it through it should pass through rather easily. Feed as much of it in there as you can without actually losing the end you're holding of course... and then go to the inside of your car and look around for the wire. On US cars, the wire would come through right below our steering column, but since your steering column is on the wrong side it'll probably be somewhere beneath your glove box. I assume your battery is located on the right hand (your passenger side) of your engine bay as well? This should give you a pretty straight line from the battery to the entry point on the firewall.

From there, assuming you are mounting your amplifier in your trunk (I just can't bring myself to say boot, sorry), you can run the cable beneath the door sill (the plastic strip that runs along the edge of your carpet when the door is open). The door sill just pulls up, there are plastic tabs holding it in place. Then the carpet, which has a plastic rail along its edge, just lifts up, and you will see other wiring down in there, where you can run your wiring as well. Continue it by running it behind the trim in the back seat, probably then beneath your seat (I have a hatch back, not a coupe, so I'm not sure about this part) and into your trunk.

You can also run your remote lead from the back of your stereo the same way - behind the stereo deck, along the inside of that firewall (beneath the carpet), and along that trim to the back. Naturally you're going to need to purchase some extra wiring and some wiring connectors to achieve this. GET THE WIRE CONNECTORS - don't just twist the wiring together, that's just cheesy. 16 or 18 awg wiring should be sufficient for this I believe.

The pic i posted of the gromit was on the driver side..i took everything off underneath the steering wheel (forgot to get a pic) and i couldnt see the cable..il try tomorrow and deffo get some more pics..thanks for the tip though

[sanjuk]

right..

I cut a hole in the grommit.wire started going through and i was thinking result..then it stopped and no more wire would go in, took the glove box off and couldnt find the wire, took the undercasing off under the steering wheel and still coudlnt find the lead:(..where is it hiding??

So then i ended up putting it undernath bonnet towards the passenger door

When disaster struck

Tried to put the connecter back in..


Is that power lead now fuked? Also ive heard running the power lead like the way i have is dangerous? Any ideas?

[Spider77]

Yeah, running it there causes it to get pinched...at least thats how it looks in the pic. As far as the cable being jacked, I dont think so, you just need to cut it, try to solder the wire and get a new connector.

Yeah ive taken it out..just going to looking around till i find somewhere..cant even use the ac gromit as it goes directly through the shell

[Spider77]

Im not too sure how yours is set up, I ran mine by the kickplate by the drivers side. There is a housing that all these wiring harness plug into, I popped that off, ran my wire underneath it and through there I followed the airbag wire through to the inside of the fender and ran it to where my stock airbox used to be, then to the battery. My carbide bits were stolen, so I had to find a non drilling way. Not to mention it was like 100+ that day and just wanted to get it done. It seems like youve been at this for a while now and I can imagine that you want to get it done with already. It dosent hurt to have an extra pair of hands too, but wherever you run it, keep it clear from pinch points.

[sanjuk]

with the aid of a chopstick.....



..Success:D

Ive broken something a bit serious i think but il post that in a bit
