Here is an upgrade solution that worked on my X5 and I am very happy with the sound that's being produced:
Old: BMW HI-FI Amp with 5 speakers (5 tweeters + 5 mid-ranges) + 2 subs
New:
- 2 McIntosh Power Amps (6 channel 50w each)
- 1 Audison bit one sound processor
- 2 EarthQuake Sound SWS-8X 8" 2-Ohm 300 Watt Shallow Woofers (under fr. seats)
- 1 Focal 8" Sub-woofer 600w (in trunk area, built box)
- 7 Hertz 100's Mid-range speakers
- 7 Hertz HT-25 Tweeters
All connected directly to the BMW CCC head unit (which I am planning to replace with CIC in a few months)
Amazing improvement over the original BMW System. Barely any fitting adjustments needed to be done.
