Running Cable through Firewall

[M3HMI]

Hi everyone,

I've decided to install subwoofers in my 2020 KL1 right-hand drive Leon. I've tapped my RCA into the audio wires on the driver's side kick panel, but I'm having trouble running my power cable. When I ran the power cable to the passenger side footwell and removed the carpet and panel, I couldn't find a way through the firewall to pass the 0 gauge wire.

I watched a video on a Formentor where the guy found a grommet, cut it, and pushed the wire through, but my Leon doesn't seem to have that. I even removed the battery and some foam in the engine bay but still couldn't find anything.

If anyone knows where a pass-through in the firewall is, I would really appreciate your guidance on how to find it. Any help would be greatly appreciated. Thanks!

Hi there,
Thanks for your reply to my post. I have a couple of questions. First, is there a grommet located down and slightly to the right of the ABS pump, or is that the best place to make a hole? Secondly, I removed my battery, but there doesn't seem to be a lot of room. Do you have any suggestions to simplify this job? Also, will the grommet be visible, or do I need to remove the sound deadening material? I appreciate your help with this and will be purchasing some items from your website for this job. Thanks.

The grommet is behind the abs pump, to the right. Easier to see from the engine bay than inside
