D3 front drivers side speakers

[B17NKA]

Hello All

Can anyone help me, where is the drivers side front door and drivers side dashboard speakers cross over unit are or are they independently driven off the amp
My car only has the standard hifi system in, no bose or b and o
The dash speaker keeps going off when I start the car the drivers side door and dash speaker are either on or off ? I didn't realise the door speaker was off as well as I have just replaced the dash speaker, mids and tweeters are normally split with a cross over but where is it ?
I have spare cross over units off my car hifi competition days but need to find it so I can cross it off all to check

Regard Andy
