Question 8 gauge wire through bulkhead

Looking for a bit of help here aas to where to put the power cable through the bulkhead (preferably on the passenger side) for amp wiring.

Have had a quick look at the engine bay but can't see anywhere obvious. Would really want to do this without drilling holes.
Are there any spare/large enough grommets to use?

Hi mate,

I'm not familiar with the layout of the Laguna but I had a sub fitted to my Clio and the power cable (4 gauge) fitted through the grommet/hole that is there for the bonnet release cable - on the Clio it is on the passenger side just up behind the glove compartment, visible internaly if you are nimble enough to reach it! In the engine bay, it is covered from the top by the screenwash reservoir but this will probably differ 100% in the laguna!

It may be the same on the laguna in terms of the grommet, but I don't know for sure. Someone with a laguna who has a sub may pop along soon and give you a solid answer though

Hope this helps however

I had one fitted to my old 1.8Rt Sport.

In your top pic there's a grommet below/behind the brake servo where the loom comes through from inside the car to the engine bay. It's located just above the chassis leg if I remember correctly.
You can either remove the glovebox ( very fiddly job IMO ) to enable access to the grommet, or as I did ........ lube up the existing wiring at the grommet and push through the power cable from the engine bay.
The cable tends to coil up behind the glovebox, but you can see this from the footwell and can pull it through from inside.
You can then run the cable under the finishers along the door openings into the boot, if that's where the amp is going.


I think I have CDO. It's like OCD, but with ALL THE LETTERS IN THE RIGHT ORDER
