Right, finally Sabas guide is back up, and it’s awesome. However I’m not a fan of running my power off the 30amp supply in the back, it just doesn’t seem right to me. So here’s my how to guide to install a power cable from the battery, to the boot.
1. Get all your wiring and stuff ready.
Image

2. Disconnect your battery.
3. Open your passenger door and pull off the side panel with your fingers.


Image

4. Open your glove box; there will be 5 torx screws. 2 at the top, one in the middle inside the box and 2 at the bottom under the box. Slide the glove box forward and it’ll drop, be careful as you need to disconnect the terminals for your light and the hose for your air conditioner pipe.
5. You should now be left with a gaping hole. Peel back the bit of insulation circled red in the photo.

Image

6. Now look closely and you will see a bunch of wires going through, this is how you access the engine bay. Get a small screwdriver/sharp pointed thing and pierce a hole in the thin rubber surrounding the wires.
Image

7. Now look in your engine bay, underneath a bunch of stuff you will now see your screwdriver poking through.
Image

8. Go get your cable, and gaffer tape some wire to it, coat hanger does the job fine.
Image

9. Poke the wire through the hole you made with the screwdriver, depending on the size of your wire, you may need to use a bigger screwdriver to make the hole bigger, try not to make it too big, we want to keep a good seal around the cable!
Image

10. Now look through your engine bay and find the wire, pull it through gently.
Image

11. WOOP, we now have the cable in the engine bay.

The cars filthy, it got hoovered and washed straight after the install! i only got the car a few weeks back and so thats exactly how i got it :p i do take care of my cars, but i only have so much free time, so i figured id get the diy jobs over and done with before i tended to cleaning the car nicely.

The sub is about 6 years old, and had an awful life...yet remains fantastic sounding. I really couldnt care a less about its looks :) its got character! Its had numerous bike pedals and beer bottles hit it. Doesnt matter anyway, they are cheap and so who cares :cool:

17.Move to the back and do the same, remove the trim and tuck the wire in.
18.Now the last trim is slightly under the rear bench. Pull up the rear bench from the back; don’t remove it completely as you don’t need to. Now feed the wire under it and into the boot


Image

19.Refit all the trims; they should click back in places perfectly. Push the rear seat back down.
Image

20.Now you have a cable in the boot! WOOP!
Image

21.Now follow SABAS guide and get fitting your rca cables, earth and remote.


22.Reconnect the battery.


23.Enjoy

12.Now assemble your fuse holder onto your wiring, have about 1 foot of wire off the battery, then the fuse, then the rest of the wire.



13.Add the wire to your positive battery clamp. Tuck the amp wire in, use zip ties or whatever to keep it safe from hitting anything it shouldn’t.
Image

14.Now you are done in the engine bay for a bit. Go get the rest of the wire and get installing!
Image

15.The plastic strips on the floor literally just pull off, I used my fingers cos I’m hard, but some ladies like to use trim removal tools…it’s not really necessary but whatever. Start with the middle piece shown as that covers over the pieces that to either side of it. Now pull off the one that sits in the foot well.
Image

16.Feed the wire through and underneath the carpet in the corner.
