A3 8v Cabriolet, adding subwoofer to B & O

[DaveTRave]

Morning everyone 

Recently bought an A3 Cabriolet (8v) with B & O, but was surprised and disappointed that it didn't come with a sub like the other 8v's.

After a lot of research and help from fellow owners, I managed to retro fit an In Phase USW12. 

It took me a while as I didn't want to rush it, but after much swearing I got there in the end! It would definitely be easier if I had to do it again! 

I'd recommend the addition if anyone is thinking about it, it's transformed the audio experience completely. 

Finally, huge thanks to anyone involved in my information gathering along the way, there's no way I could have managed it without that help. 👍
