I have a sub with mono amp on the old 3.0i when I sold it. I tapped the line output converter into the rear speaker wire for signal to the mono amp.
I'm waiting on the passive crossover that German Audio Solution develop for DSP system (E39 and E53) My iS seriously lack in bass. The crossover will get rid of the DSP amp, then your head unit will convert back to analog automatically. I'll power everything with a 5-channel Alpine amp and run a JBL 12" in the custom sub-box in place of the DSP box.
