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!

I have a 545I and i added a EQ to my stock head unit. From there i was able to run 2 amps and change all my surrounds with memphis speakers and custom built box.

" How much " of an upgrade are you leaning towards, and how much are you looking to spend. Its really as simple as upgrading your current amp to an appropriatly stronger amp, to replacing or adding more component speakers/ subs, to a complete front - rear stage upgrade, or just simply replacing the subs to fill in the low end. Your options are plentiful. As the audiophile needs could potentially be ENDLESS, the only limit at that point is the financial budget for such a project. If this is a project your would like to tackle on your own, there is a wealth of imformation reagrding sound systems, in other "audio" forums, as well as 5 series "specific" audio knowledge within this forum, in any case, the "SEARCH function" will quicky become your best friend in your pursuit for knowledge. PS.. we LOVE to see LOTS of pictures of projects and upgrades being done heres somewhere for you to start your research; https://5series.net/forums/topic/477...plug-and-play/ Bruce's post documents one of the best ways to upgrade when low cost + effective improvements were considered. In addition, his methods also implement OEM like pnp connections, which is a HUGE plus to many e60 owners.
