I find this to be really strange.
I mean the coding to HiFi makes all outputs normalized if I've understood it right.
And since the rear speakers are the only speakers still driven by the headunit with the Alpine retrofit it is very logical that their volume is reduced.
But then it would be the same for all cars getting coded...

Can you answer me the question quoted below?

Or is the "Plug & Play" cabling for the newer E90's without this filter all together so that's why they require coding?
I am really sorry as I have not installed the kit yet, so cannot answer the question.
As far as coding is concerned, you will be amazed how many things are possible just with coding.
One example is BFD (see coders in UK thread).
