How to get a 4awg power wire through the firewall!

Featured Replies

Hi all.

I'm midway through a project involving installing aftermarket amp in the boot of my Fabia Mk3 (1.0 TSI, RHD). However I can't for the life of me find a suitable, accessible grommet to route my 4 gauge power cable from the battery to the interior.

I've removed the glovebox and kick panel, but still can't find a grommet. I've tried the one underneath the scuttle panel on the passenger side, but the seal is way too tight to accommodate an additional cable.

If anyone has successfully routed such a cable on their RHD Fabia, let me know what grommet you used and if anything needed to be removed to gain access!

Any advice would be really massively appreciated
Cheers

Not on a fabia but a Seat. The grommet that you mentioned thats too tight on mine had enough rubber at edge to push a length of fencewire through to engine bay and then taped cable to it and pulled it back through. You could also try snipping end off arrow marked and feed cable through there if it has one. Use vaseline etc to make cable slide easier or as I did stiffer wire first so you can pull it through.
