Purchased a Beosound 2000 and I really like the sound. However, I would like to add a subwoofer output to add a some more bass to the sound. Has anyone tackled this before? I mostly use the aux input with a ipod or computer. I was also thinking of using a car crossover  but would really like to have something more integrated in case I want to use the other sound sources, I was thinking of using the headphone output, soldering rca leads or something similar to that. Thanks for any replies !
