I am about to install a Pioneer DEH-P8400BH in my 2002 325i with HK. This thread is just what I was looking for. There are many threads with stock HU and aftermarket amps and speakers but not many with the reverse.

Hopefully the speaker outputs on this HU will work well with the HK amp and speakers.

Thanks a ton, OP.

Would appreciate seeing pictures of this unit and hearing about your experiences with this head unit. Why did you pick this over the 9400?
