Cross-overs in doors
 

I know it's not a good idea at all to put your cross-overs in the doors because of moisture issues. I was wondering if there was some way to have them in the doors safely? Maybe if I wrap the cross-overs in plastic, although that just occerred to me that that might be even worse because it may trap even more moisture.

The reason I'm asking is because I'm running me wires in a 2005 Mazda 3 sport. for you guys out there that know what the door looms look like you might understand.
here are a couple pics of what I'm dealing with to get my wire from the cab of the vehicle threw to the doors

First picture is of the rear door loom, as you can see it's accually a plug. You have to unplug it from the outside of the vehicle, then you can get the inside plug out as well. In this shot you can see that I had a little bit of space that I was able to drill through and push my wire through that.

Here is that same plug(inside part of the plug) with my wire run through.

Now the front plug is a little different, it's a little bigger, and has a few more wires. I could probably have enough room to drill another hole for a second wire, but I don't really want to drill another hole.
this is the inside plug with hole already drilled and wire pushed through.

and this is the outside plug, same thing, hole drilled, wire pushed through.

and here is the front door with the loom put back together, as you might be able to see, even the loom itself is limited in space for another wire.

Any suggestion on safely placing the cross-over inside the door? I only need to do this for the front door. I have decided that I want coax in the rears door. But there is now way I'll have anything but components in the front.

Thanks guys

We try to keep them inside, but when necessary, we mount them to the inside of the vapour barrier.

Nice job by the way.

thanks.

you know whats kinda weird that I didn't notice yesturday. This car doesn't have a plastic vapour barrier like most cars have. you can accually see in the one picture.:dunno:

Some don't have vapour barriers now. I agree with the above, put it on the interior side of the metal door skin.

thanks, I'll prob do that...I'll let you know what I decide

The Ford Focus version of that car has a large foam piece under the arm rest I chiseled out the foam for a place to put my passive. there are lots of little nooks you can use... no big nooks just little nooks

thanks....I'll take a look when it comes time to install the speakers.
when you say the ford focus version, do you mean the mazda 3 sport(hatchback)? Thats the car that I have, mazda 3 sport.

The grey cable that you have added and drilled a hole for, is a 2 conductor or 4 conductor cable?
If it's 2 conductor, can you replace it with 4 conductor, to connect the tweeter and woofer? allowing you to keep the crossover under dash.

it's a 2 conductor, black wire and red. I thought I had some 4 lahing around but I couldn't find it, maybe I'll look again.

Nah the Ford Focus and Mazda 3 have been the same frame for some time and a lot of the internals are similar (similar plugs for wire connection). The Focus has a big foam piece that is the perfect place to mount a passive cross-over
