It's not really that hard to do.

You will need to run the the line out cable from the head unit to the amp and a power cable from the battery to the amp. Then earth the amp to a point in the boot floor.

Try to keep the line out cable and power cable as far apart as possible.

You may have to remove the passenger seat to make lifting the carpet easier.

Its really easy, best way to learn is do it yourself.
Just watch where it leads you, you might get a tad involved and end up with damaged hearing, like me!

It's really not very hard to do:

1. Route power cable from battery down the passenger side sill of the car, you don't need to take the passenger seat out for this (I have 4 gauge wire and it's fine) You can either drill through where the top glovebox/airbag is or find the existing bung for the A/C and drill through that. Make sure if you're drilling through metal that you use a rubber grommet so the metal of the bodywork doesn't cut the power lead. I also used a bit of silicon sealant around the hole to stop any water getting in.

You will be able to route the cable to the battery and cable tie it out the way of any engine components. You will need a fuse just after the connection to the battery, no more than 1metre away, this can be mounted somewhere or just cable tied out the way.

2. Run a set of RCA leads from the centre console (where the back of the head unit is down and next to the gearstick). Follow it down and you'll be able to push the leads toward the back seats (on top of the "lump" where the exhaust tunnel is). You can then push them to under the rear bench and into the boot.

OR

Run the RCA leads from the back of the head unit and underneath the fusebox in the drivers footwell. You can then run the leads down the sill to the boot just like you did with the power cable.

3. You will need a 12v feed (normally a thin blue wire) from the head unit to the amp to tell it when to turn on. I used electrical tape and attached it to the RCA lead as that's the easiest way.

4. Make a ground lead (the same gauge as your power lead) and find a point to bolt it to bare metal. I drilled a hole underneath the rear bench where I could get my hand either side of the metal. Sanded the paint back to bare metal and used a nut and bolt to secure it. Be careful not to drill into the petrol tank!!! (If you have any sense of direction you'll find a nice spot well away from the tank!)

5. Last of all is to wire it all up. Make sure the last thing you do is put the fuse in, last piece of the puzzle.


It's really very easy to do, and you'll wonder why you even considered paying good money for someone else to do it.

Any questions just ask me and I'll be happy to help

no need to drill anything mate

I'd like to know too, i couldn't find anywhere to get a wire in without drilling on my hdi.

I'll just work using a mirror then, that would be great though mate as I'm very new at this kind of thing

I wouldnt drill for the ground mate, just screw it to the back seat bolts that are used to hold them to the car.

On my install in my old 1.4 (two amps, subadub, amped front components, sound deadening, tweeters in a-pillars) I drilled from a hole behind the glovebox removing a little OEM sound deadening first. But on my 6 I found a handy rubber bung and forced a BBQ skewer through and gradually made the hole bigger. Then just fed the power cable through there.

The powerlead i'm using is 35mm², so 2awg/gauge?
This made it a hard job, but anything up to 25mm² (4awg) is a piece of cake.

i'll make some overview pics and draw on them

the thing you see here is where the powercable enters the car (the cable is black ribbed sleeve-thingie for protection.



Lets start at the battery.
Short piece (+-25cm, so 10"?) going to the fuseholder (mine is not located at an ideal spot, but due to the size of that thing i havent found a better option; you will probably have a smaller one, which will me more easy to place somewhere else)

From there, the cable goes into the ribbed sleeve thing, under the battery/ecu, I recommend using such a protective sleeve, just in case it starts rubbing against something and breaks the insulation (= shortcircuit).
Behind the ECU it goes up, and right into the corner next to the strut. (in my case, between strut and brake-cylinder)
In all the 306's I've owned & worked on there is/was a rubber grommet in that corner.
Take it out, make a hole in it, just big enough to put the cable through (2awg is the max size you can feed through it), and put the grommet back in, then start putting the cable in.
Cable comes out high in the dashboard (you'll have to shove your arm up there)

IN:
OUT:
the metal you see is part of my pedals (LHD-car, remember?)

(old pics tho', without the sleeve/grommet, but this is 0awg)


Is this clear enough? (before I continue with the easier last part )

Multi-amp setups require much more work and details to look after compared to single amp setups.
Very depending on specs and sorts too. (a bit hard to do a complete write-up for such things)
But I'll gladly help out with more specific questions.


More on the cable routing when i get an overview pics to draw on where the cable continous to run
(thursday maybe)

Ha never noticed that hole after I've just drilled a hole yesterday!
