Okay, one thing I have noticed it that the E39 has very little to no bass at all. Dare I say it, the bass sounds worse than the e36.
I have two questions for the system;
1. How can I get more bass from the E39 without changing the Head unit (I will change to a sat nav/dvd one in the future)?
2. I can see that I have 3 speaker grilles on each front door, 1 on each rear door and 2 on the parcel shelf....however sound only comes out from 2 on each front door, no sound on each rear door, and sound on the parcel shelf. After doing some extra reading, I've found out that the standard system had 6 speakers (probably mine even though i can see 8 speaker grilles) and there is also a higher spec called DSP. What I want to know is, did BMW pre-wire and fit speakers in all the grilles whether the buyer chose the DSP system or not? If so, how could I make sound come out for the remaining speakers?
