Rear bulkhead air vents

[David Goodwin]

Another beginners question.

Reading the Chimaera Bible tells me that if you use the rear bulkhead vents for speakers, you need to add extra vents to assist with de-misting. That makes sense.

What he doesn’t say is if there has to be a vent in the boot panel/carpeting as well or if you just have to let the air into the gap between the two. I have seen a few cars with air vents but do people have vents in their boot above the tank?

I have rear speakers and no vents in my car, yes it will mist up in cold/rainy weather much like any other car, and yes it's bad at clearing that mist because it's not a very well sealed 1990s hand built TVR.
I wouldn't worry about vents.

Mine has no vents and no problems. Shouldn't mist up unless you have moisture in the car, e.g. damp carpets.

Just be careful not to shut the boot lid too fast as it will force air through your speakers into the cab, which I would think could damage them eventually.

With the Ventilation Controls set to the Upper Vents of the car and the Central tunnel vent turned off, not forgetting to turn Heater control Control set to Max.Temperature - Turn the Fan Speed Control Max, then Press Fan Speed Control button to the Second Speed for Max. power.

The screen would hopefully demist quite quickly.

So the general view is:
1) No one has vents inside their boot above the tank.
2) I don't need to worry about venting the cabin anyway.
