Hi,
After almost a week of scrolling thru the topics I am still not able to follow a certain path...
I wouldn't opt for the Alpine upgrade nor for the Blaupunkt one...I feel more for a stock speakers upgrade but here it comes: which ones?
I have an E90 with standard 6 speakers and Business Navigation (professional radio)...so far I saw people using Hifonics (HFI42) en Infinity (4012i) but not so many with Audio System (AUDIO SYSTEM CO 100 BMW or XION 200). Please help me make a choice!
