It doesn't seem that there is a rear output that I could plug into unfortunatly. Is there any particular place in the firewall you would reccomend? I have noticed that a number of folks in the US have poked a hole through the firewall where the steering column exists. I guess this would be ok though the cable would ahve to go all the way over the other side of the car.
. Hi rob,
I wouldn't make a hole in the firewall mate,
If a hole is made in the firewall
It creates vacuum in to the cabin when driving,
In the unfortunate event of fire,
That vacuum will help the fire and pull it in to the cabin.
Search the engine bay for an empty grommet or the location of the loom coming through a rubber grommet from the inside of the car.
Undo the PVC tape on both sides of the grommet,
Push your sub cable through and tape it up again.
Avoid running power cables across the engine bay or close to moving parts mate.
Its worth taking the extra 30-40 minutes on a job like this.
