Sorry if this has been mentioned before - I searched, I really did I'm looking to replace the front and rear speakers on an A4 B6 Saloon, which has a standard/non-BOSE speaker setup. I already replaced the HU with a Kenwood KDC-BT61U and have it working as it should... Life is great, except for the crappy sound quality that is the standard Audi speakers. I'd like to replace the speakers with quality after-market units and possibly look at replacing the sub also at some point. I plan on running the cabling to the rear to facilitate that at same time as the rear speaker cables as well as the usual addition of sound deadening. Does anyone have experience with doing the above on this model? I'd love to hear what speakers will fit in the front and rear and if I need any sort of adapters to get them to fit. I'm pretty bad at DIY, so making the adapters myself is probably a bad idea. If these can be bought from someone, I'd be happy to send some beer tokens you way. AndyMac, do you have any ideas about this seeing as you helped me massievly with my old 8L S3 a couple of years ago?
