Martyn85 Posted April 20, 2020 Share Posted April 20, 2020 Hi all, wondering if anyone could help, I'm getting ready to install sub and amp in my a4 cab, I was wondering if anyone could help with access through the firewall for the power cable? Is there a grommet that comes out anywhere close to the battery? Hope someone can help. Thanks Quote Link to comment Share on other sites More sharing options...
Steve Q Posted April 20, 2020 Share Posted April 20, 2020 Hi Martyn, I think if you look near to the battery you should find a grommet or two, which come out the back of the glovebox. You may need to remove the back of the glovebox to get at them from that side. In failing that I think there's one near the ECU. You'll have to remove the ECU housing to get at it. To do that you have to remove the wipers to get at all the torx screws. Another more way out option is to take the wire via the pollen filter housing.

Martyn85 Posted April 20, 2020 Author Share Posted April 20, 2020 I've found one just to the right of the battery. Was going to take glovebox out anyway for a tidy job. Thanks for the reply Steve Quote Link to comment Share on other sites More sharing options...
