First, the easiest question. " 460 AUDIO SPEAKERS" > Don't worry about that. It's for older models. You need to change 028 RADIO, AMP AND SPEAKER SYSTEM according to the AUD (Amplifier) if you replace it and 201 SUBWOOFER if you add a SUB.
Your car has total 9 speakers.
2 tweeters on the front pillars (L & R)
1 Center on the DASH
2 MID range on the front doors (L & R)
2 Woofers on the rear doors (L & R)
2 tweeters on the rear doors (L & R)
So, you are missing 2 roof "back pillar" (MID + HIGH) speakers and the SUB woofer.
There is also another SUB under the glove box. Not sure if you have that.
According parts link, Woofers on the rear doors (L & R) do not have variants. Only one part number. So, you do not replace them at all.
What I would do,
First determine if you are getting any output from SUB woofer by enabling 201 SUBWOOFER = SUBWOF.
Just push two wires into the pin wholes and the other end to random LOW band speaker. Check if you get any audio. There are people here who just tested and and it worked. You should get audio if VOLVO EU not played cheap. :-).
At the same time test the roof speaker outputs with the same method. If you get audio, then you don't need to replace the AUD, just add the wiring and the roof speakers.
If you don't get any audio,
First from Orbit change the 028 RADIO, AMP AND SPEAKER SYSTEM > High Performance Plus Audio. (H&K) , then retest the roof speakers. You might get likely that could enable the roof outputs.
In general AUD part numbers are shared with all models. The software and the config file is different for classes. (40, 60 and 90).
You can use a voltmeter too for testing. Put it on DC 2Volts for measure. Take your time when testing, especially if you are using wires to test.
Don't rush to spend money to buy stuff. It might not just worth it.
By the way, HK speakers are just ok. There are much better speakers out there for cheaper price. So, first test your AMP. try to enable the outputs then decide what you want to do.
I've never listened to output of the basic AMP so I cannot tell you if HK is better or not especially with SUB and roof speakers are connected to basic AMP.
Don't worry about the questions, I like to help people as much as I can. Sharing is caring :-)
