Yea I agree. I like good sound, use floor standing B&Ws at home. The stock setup in an e34 does an apalling job by today's standards but once you add a 5 channel mothafokka amp) and a decent sub its amazing. And smooth, no strange harmonics, sharp top end frequencies, and no equalisation needed if one uses the stock crossover. I didn't even bother changing the stock (10) speakers... priceless!
