    Hello All,
    I've just joined the forum today and wanted some advice.
    I'm going to be replacing the factory head unit on my wife's B5 A4 saloon and am going to be using an old amp that I have to power the rear speakers. I need to know the easiest way of routing the power lead through the bulk head to get to the battery. I can't see any obvious routes.

    Any ideas? I'm sure many of you have done this before, so how did you do it?

    Thanks in advance.

  2. up through the bottom right side of dash where ECU is, drill neat hole in side of the box, seal hole with black sealer and along to battery, easy!

    ^^ what he said, ECU box is perfect route, even easier if you poke it through one iof the existing rubbers as it seals itself up if you gont make to lagre a hole

    Yes alot easier to feed the cable from the engine side down into the drivers footwell, there is already a spare grommet, no drilling necessary

    Agreed its right by the battery too so you will have more + cable to play with in the car. Here is a few pics of the routeing (I put a sub in mine last week).........

    The route from the battery....

    The grommet it goes through under the pollen filter housing.........

    And where it will protrude in the nearside footwell (this is made much easier with the glovebox removed)......

    Hope this helps you.....

    I'd take it thru the ECU box, rather than disturbing the heater.
