Re: ICE ICE baby - The Basics
IMHO, The better way to mod ICE for BMW car(including continetal car but excluding Japanese Car) is go original:
Top Level:
Audi and BMW please choose Bang & Olufsen; Porsche please go Bose or Burmester, Mercedes goes for Burmester or Harman Kardon.
2nd Level:
BMW: Harman Kardon, Logic 7, Tophifi
3rd Level:
BMW: Harman Becker, Hifi
First of all, the sound source plays the most important role for the sound quality. For BMW, Top Level and 2nd Level use MOST optical fibre to transmit the sound from the Head Unit to Amplifer. As we know car's power are take from alternator, which is also a noise generator, but by using the optical fibre, these noises are fully filtered because optical and electric signal are completely different.
2nd, as one of the bro mentioned above, the connection in the door hinge is critical too, after market cable have to look for a limited space to squeeze the cable, but original cable has its original connector, which is pin-bushing 100% connector to connector, instead of using those China Made clap-in connectors.
3rd, Original speaker has it original fitment and size, which will avoid using this and that extra mounting boards and fixtures which will unbalance the sound.
4th, All the equallizer and balancing system are fully controlled by iDrive through CIC or NBT, no extra buttons dangling there, avoid any bothering when go back for servicing.
Surely, original solution is a bit expensive. but we believe this is the better way to mod the ICE for BMW.
