Retrofit Volvo V60 B&W

[spacemanspiff]

Foe those who would like to upgrade from high performance / HK to B&W on S60, V60. 
There are many listings for B&W AUD and Speaker set on ebay pulled out from S90, XC90, XC60 but very few from S60 and V60. 
It's possible to swap all speakers from a 90 series to 60 seers except the Subwoofer.  XC90 and S90 subwoofers does not fit to S60 or V60.   
HK SUB is 4ohm and B&W SUB is 8 ohm. It is possible to use 4 ohm HK SUB on B&W AUD (amplifier) but a 4 ohm High power 50W resistor must be added on the positive line of the SUB. Otherwise, on high volume low impedance (4 ohm) SUB will over load the AMP and eventually, it may burn the SUB channel.  

The second most important difference between those (XC90, S90, V90 , XC60 and S60, V60) is the speaker channels on the rear doors.
The 90 and XC60 series have two channels going from AUD to rear doors same as front doors (LOW and MID+HIGH in parallel). On the other hand, 60 series has only one channel going from AUD to rear doors. Woofer and tweeter are connected in parallels. This is same for all levels. (HK, B&W). 

It is possible to get B&W AUD from S90 and replace and s60 AUD as is but tweeters on the rear door of S60 will not work. Because s90 AUD uses internal crossover. 
If you get a full set from a 90 series and fit it to 60 series, you will need to wire a second channel from AUD to each rear door. 

DO NOT try to flash an preloaded (used) 90 series B&W AUD with 60 series B&W AUD software.  It will break the AUD completely and you will loose the volume control and all sound (including turn signal sound).  So, just wire second channel from AUD to each rear door.  

You will need  
4 repair terminals 30656669. (for the AUD middle connector) 
For wiring from car to doors I purchased used door harness for $35 and used the pins for the door connectors. I wanted to keeps things clean and original. 
Or you can pull direct wire from AUD to tweeter. 

I also added MID speakers to my rear doors. I build small boxes for the mid speakers and placed them in the small storage are on the doors.  Kids were using the place for trash anyway :-).  

On the back shelve I replaced the speakers with the ones with tweeter too. It fits inside, I just needed to cut a small piece to make a room. 
 
So, now I have 19 speakers in total on my S60 and sounds awesome.   30656669


It's possible to swap only the AUD without the speakers it still sounds much batter than HK but, the volume must be kept below litter over the middle because the HK speakers are 4 ohm to 6 ohm and the B&W AUD is designed for minimum 8 ohm speakers. 

Whoever is interested I have B&W S90 Subwoofer and complete set of HK speakers available for sale.

Is there any harm running the 8 ohm BW subwoofer off of the 4 ohm HP amp?
