2015 B8.5 A4 Avant Main speaker tear down pictures.

The centre speaker has already been disconnected see previous post.
I was amazed at how much (harsh) mid range comes from this tweeter.
The bass units in front doors are bigger than expected and bigger than the sub one .
Hope this helps people, as I needed to know what was there before I did anything.
For sub tear down see previous post.

Looking through the Alpine upgrade manual for the SPC-100AU woofers and tweeters ie 2 way and SPC-200AU extra amp and 3 mid units (see link below), it appears that full frequencies come through to the main speaker cable as it splits it and uses a crossover inline to split the woofer and tweeter ie 2 way see page 30 and 3 way if the extra amp and mids fitted see page 56.
it also shows you where to place damping material on page 21, also how to remove the door panels.
Unfortunately the alpine upgrade is well out of my budget but it looks goods.

So it looks like these are classed as 20cm din size, I may just try my mac Audio 16.5 cm components in place with an MDF plate and tweeter on the plastic where the door mirror is mounted. Just got to find time to do this.
