need to set up front door card speakers

[xpress]

hi there. where can I route the speaker cable for front door card speakers to get them back in the cab floor? will I need some weatherproof shrouding?

thanks.

That's a good question - I was going to post to ask the same thing. In the rush to prepare my van in the brief time I had it before going on holiday I just used a bit of mains 2-core flex (to get the extra layer of insulation) and threaded it through the gap between the door card and the door. There has to be a better way, but it's not obvious where to drill.

There is a hole in the door that lines up with a hole in the body.
You can feed the cables through this, ideally you should also fit the rubber trunking that goes betwixt the door and body.

The trunking pops up now and again on ebay.

In my van there's no hole except the large airflow ducting hole - is that what you're referring to? In which case, the ducting channel inside the door would have to be drilled to get the cable into it. Is that right?

Sorry to hijack the OP's post - maybe his is the same, hence the question.

I can't remember exactly how it is but I am sure that it's the airflow hole.
The hole in the body side can be on the lower face of the box section - no drilling required.

I can take some photos for you but not until later this afternoon.

If you zoom in on this photo you can see the rubber trunking going from door to body.

Thanks - that would be helpful. I'm installing new door cards and speakers this weekend, so I thought I'd have a go at getting this right. When I looked earlier in the summer, I'm pretty sure there was no obvious way to get from the speaker cavity into the ducting channel, other than by drilling a new hole. It makes sense that the ducting is as airtight as they could make it. I didn't investigate the ducting channel on the body side, but I would have thought the same thing applies there - it's probably airtight except at the vents, so I had assumed I'd need to drill that too.

E D I T: Sorry, your post arrived while I was writing mine.

Ok, that's useful, thanks. So I'll take a longer look at how to get the cable into and out of that ducting then.

I'll try and get some closer shots when I get home this afternoon.

Have a close look at the internal design of the ducting, ie, were does it go to and from.
Then look at where it goes to at the rear (pillar).
Then examine the plastic adjustable vent at the lower rear of the door, try to work out where it connects to the vent that runs through the door (it doesn't by the way )

It's all VERY odd

There was a thread about it a while back, it's summat to do with an earlier design and Caravelle mini buses that had fresh air vents in the rear roof.

Yes, I did read some threads about this earlier this morning because I had a vague memory that the vents weren't used, and I was considering removing them altogether and just shaping my new door cards to to suit. One link that was mentioned in a previous thread was this one, where it seems to suggest that the door vents are used to extract air from the cabin and vent it outside via the front edge of the door. Is that the consensus? If so, I'll leave the vents, and although I'd put grommets through any holes that I drill I'll not lose sleep if they're not airtight.

Sorry again to the OP, this first bit is a bit off-topic.

...where it seems to suggest that the door vents are used to extract air from the cabin and vent it outside via the front edge of the door.

It looks like that theory might be right. The air vent at the bottom of the door card vents into the door cavity, rather than the air duct. There is a row of holes in the front edge of the door (outside the door seal) that seem to be in the low pressure area just behind the front panel. So it looks as though these vents do indeed suck cabin air out. That also seems like a good way to get airflow through the door cavity to help dry up any water that gets in there. So I'll not be blocking off those vents with my new door cards after all.

Now the on-topic bit. The air duct through the door has a hole at the front edge and a hole at the back edge, and that's it (apart from a small hole that's supposed to be plugged with a door card clip). If this is supposed to carry ventilation to the back of the van, then it's never going to be very effective in my van because a) there's about a half inch gap between the door holes and the mating holes in the A and B pillars, and b) my van doesn't appear to have any vents in the back anyway. So keeping that duct airtight isn't important. I shall be drilling into it from inside the door cavity in order to feed the speaker wire into the duct and then into the van.

Here ya go.

This is the right hand side.


You can see the end of the rubber trunking and the cables poking out of the upper face of the box section.

Thanks Titus

I'll follow the same route then. In my case there's only the speaker wire, so I won't bother trying to get hold of the trunking - my round mains 2-core cable will be resilient enough I think.

Interesting to see the seal around your air vent ducting - that's another thing that's either parted company with my van in the last 30 years then or was never fitted due to the lack or rear air vents.

the seal between the door and the hole in the door is only there if it is a high spec or maybe late model van ie caravelle ,bus , carat , as its used for the factory electric windows and central locking but it is fairly easily but awqward to drill a pilot hole then cut the hole in door with a hole cutter then just fit the rubber parts of a caravelle to give a factory finish
