: I'm was very interested in your a/d/s/ site and the upgrade diagrams for the E39. Is the upgrade different if I have the premium+DSP setup? For example, if I replace the factory subwoofers with yours, will the BMW "premium" amp drive them sufficiently? I mean, BMW claims some ungodly power rating on their amp (but I don't really believe it).
Bob can respond about the rest of your questions, but from digging for information about factory BMW stereos, I know that BMW rates their amplifiers at 10% THD! Ouch! That's how BMW can report such high wattage. At a more realistic THD, the BMW amp isn't anywhere near the wattage they advertise.
