2. What about the HU? Did you retain the OE head unit (Bluepoint?)?

3. How did you power the tweeter? Did you use the HU output itself with a crossover or did you power it using the newly installed amp? [This question may be dumb, but, please enlighten].

Anyway, thanks for the ideas. And, I now can imagine an ICE upgrade for my Cedia too.
Please see the pics a bit closer...

1. Actually, we used Alpine X type components in the front. The Rear OE speakers were retained as they are not used. The fronts are powered by two channels of the Four channel amp, the other two channels power the sub.

2. We used an Alpine 9887 HU instead of the stock Blau.

3. The tweeter is part of the front component set thats powered by the amp.

Cheers!

Ya they are very talented.

When FB first met us the crossovers were installed (kept) inside the door where rainwater etc would have damaged it. They also damaged both the crossover housings by cutting the sides with wire cutters, to route the wires from the side of the crossover, instead of from the bottom. The only thing they managed to get right (by chance) was the tweeter location. But if they had got it wrong, they had cut through some expensive Mitsubishi door panels.

All this by the Alpine dealer while installing a pair of Alpine components? Jeez, that is sad.

All's well that ends well. Yeah.

Who knows they might be "placement" specialist.

That's closed-celled foam. Will not absorb water. I guess this is AZ-Audiocomp stuff.

(Open-celled foam will absorb water and create problems).

True. That door is *really* sealed

I was speaking generally. Even if it (the foam) comes into contact with water, it will not absorb and retain water, right?

"by chance" an assumption?

once water gets in it will find a way out. the only way to seal something is to from the outside. the foam is closed cell foam and hence will not absorb water but will still slowly disintegrate in India's enviroment, especially inside a door panel.

I think when it rains the water which goes inside the door come from the channel on which the window glass is guided and for the the beading on the top. So I think stopping water going inside door is impossible.

But preventing the speaker from getting damaged from it is a different story.

there are holes on the bottom of the door panel from where water can leak.

Navin, The water will not come inside the door panel as all the holes and openings are sealed using corrugated plastic and damping material. So the water is flowing inside the door and not coming in contact with the door panel .
If you see the picture of the door panel the original damping is also made by compressing waste cloth fibre which also retains water but all the manufacturers use plastic sheel to keep the water inside the door. Over here the plastic sheet is removed and replace by damping material.

LBM, water does get inside the door but it is escapes from the holes in the bottom of the door not the door panel (every car has them).

One cannot use closed cell foam in the door panels as it compresses less and closing the door panels will be a big problem.
