Amp Power Cable

[Elvin7]

Hello guys, any advice on where is the best place to get an amp power cable through from the engine bay into the cabin on a uk surpa?

I see there is a large grommit on the drivers side that i could use, but in the interest of keeping things neat i would prefere to keep it on the passangers side.

Any pic of where someone has put the cable through the bulkhead would be great

Thanks in advance
