If your dashboard has a grill on it with Harman Kardon label, look at the page 135. 7A_002C_External_Amplifier_Audio2+_CL90
Quote:If tweeter are in parallel,I will need passive filter for them.No, Both tweeter and MID comes with it's own attached to it. You should already have tweeter on the rear doors. You can add B&W mids in parallel to tweeter.
In the back my door card has only 2 speakers.i think the tweeter is the one missing but I may be wrong.
Quote:I will look for front center speaker on eBay.that should be plug and play then?If you purchase gen1 B&W center (yellow), it's plug and play.
Quote:Worth upgrading the third row speakers with 2 way Bower and Wilkins?Yes, replaced my HK ones with the two way roof B&W ones on my s60. It sounds much better even with HK AUD.
Quote:Looks like retrofitting the entire bower and Wilkins systemYou have two options but it's not a lot of work. It just costs money to replace the speakers. I must say, there is a huge difference between B&W speakers and HK regardless which AMP you are using.
With amp is a lot of work and requires new harness?
1) You can get gen1 B&W AUD from 90 series. It's plug and play in your case. Adding the MIDs on the rear doors is not mandatory.
But you will need to reinstall your original AUD or simply remove the power connector from the B&W gen1 AUD every time before connecting the car to VIDA. Otherwise, VIDA would detect the HW change but most likely won't let you to do AUD reload because gen1 B&W AUD is not for your VIN#.
2) You can get gen2 B&W AUD but you will need to add additional channels to both front doors and center for tweeters. see page 136 External_Amplifier_Audio3_CL90
You should be able to reload AUD since gen2 B&W AUD is suitable for your VIN. However, there is always a risk that it would not.
I have gen1 B&W AUD from 90 series for sale if you want.
