Is there anyone out there that knows how I would upgrade my existing stereo system in my 2005 530i Petrol M Sport.

The stereo system you have in my vehicle is option 663 Professional Radio and the navigation I have is option 609 Professional Navigation.

BMW Customer service tell me that on the professional radio system there is no amplifier. This is available on the optional radio system option 676 Hi-Fi audio system which I do not have.

Is there a way that I can splice wires (which i would rather not do) and put an amplifier inline with the system and if i could, how and where is the best place to splice.

I know that battery is in the boot (trunk) so this would be best position for the amplifier.

As there is no amplifier, its quite hard to know where to start as I believe that the I-drive system is fibre optic so any ideas would be appreciated.

Ive looked at the Blaupunkt option but I have been told that aftermarket stuff causes problems with the i-drive and battery IBS wire.... Anyone else who has upgrade stereo experience this?

I also need to upgrade the speakers. I have the standard hifi system (not logic 7 or professional etc) that only comes with sub under each front seat that are in line with the door speakers, mid range but no tweeters (which I will be adding later) in the front doors and standard speakers in parcel shelf in rear (no rear door speakers).

The system i have in my E60 is very basic and does not sound as good as it could do.

I had a really good system in my E39 Alpina B10 (an Audison SRX3 amp, Diamond Sub, Focal mid range and tweeters) but the electrical system in the E60 is lot more advanced and complicated.

Anyone fancying recommending speakers / amp to go in it?




I know there are a few DIY sections on this but most of them are based around upgrading the existing amp but I do not have one so dont know where to start!

Instead of splicing wires, the member named technic on here builds and sells a harness to add aftermarket amps to your system. You should hit him up.
