Fitting/wiring in tweeter A post trims.

Hi guys.
I've obtained a pair of A post trims with the tweeters in them & would like to fit them and wire them up.
I've had my finishers off & there is no redundant wiring/connectors under them.

How are they wired in? Do they simply spur off the door speaker's wires or is it a bit more technical than that?

I have seen stuff about cross-over, capacitors & resistors but that was when someone was fitting off-the-shelf tweeters to a car that has never had them.

My tweeters are OE Disco ones and have electrical gubbins on the back of them already.

I am talking Disco 300TDi, by the way, '94(95MY)

Thanks.

from what i can see on Rave brown and black wire from front speaker wires behind footwell trim left and right

Thanks for that.
I checked Haynes manual wire dagrams but drew a blank.
I will fire RAVE up when I get home but I struggle to navigate my way round it, if I am honest.

look up C2105

Thanks AGAIN but can't you just come round & fit them for me? With a fiver tucked in each one?
