Default 1994 940 speaker question

Hello, for my 1994 940 I am redoing the entire speaker system in the car I have by passed the amp already. The problem that I am having is that I want to power the rear deck and front door speakers with a 4 channel amp in the truck with after market speakers. I can't figure out how the tweeters and front door speakers are connected. I want to power the tweeters with the stereo which has 15 rms. How can I separate the tweeters from the doors and could some one send me the wiring diagram? Any recommendations are appreciated Thanks

my 1992 came with wires in the front doors but no speakers... the front doors, and rear speakers all went to the factory amp connector, while the dash tweeters went to the factory stereo connector... I wired in external crossovers for the front door and dash tweeters (using a component 2-way system).

they changed something after 1992, tho, I'm not sure what exactly.

anyways, this is how my 92 was wired.

color - aftermarket stereo wire colors... (color) - volvo wiring

notes: Dash speakers on connector D to radio
Door speakers on connector E to amplifier under driver side dash

In front, I used component speakers with crossovers, tweeters in dash, woofers in front doors, in back I used coaxials

Left front crossover:
1 front left stereo + white
2 front left stereo - white-black
3 front left door + (blue-yellow E2)
4 front left door - (white E6)
5 front left dash + (brown-white D1)
6 front left dash - (brown D3)
Right front crossover:
1 front right stereo + grey
2 front right stereo - grey-black
3 front right door + (grey-white E3)
4 front right door - (grey E7)
5 front right dash + (grey-red D2)
6 front right dash - (grey D4)

left rear
+ green - (yellow-brown E8)
- green-black - (yellow-grey E12)
right rear
+violet - (green-brown E9)
- violet-black - (green E13)

power etc on main stereo connector D
ground: Black (black pin D10)
switched power from fuse 14: Red (orange pin D11)
batt power from fuse 5: Yellow (green-red pin D9)
antenna: Blue (green-grey pin D12)
dashboard lights: Varies or NC (yellow-white pin D6)
rheostat + (white pin D7) **
rheostat - (black pin D8) **

** don’t connect these, they are for the factory dashboard light dimmer, and no stereo I’ve ever installed can use these correctly
