I bi-amped my last car setup with fantastic results. I never actualy heard it with the passive crossovers so I cant say how much of an improvement the active crossovers really made in my setup but the shop that did the install did lots of A/D/S installs with the passives and they were very impressed with the final result of my setup. I used a zapco 50w x 2 for the tweets, a zapco 100w x 2 for the mids, and a alpine amp for the sub. The zapcos have a nice dsp that you can control through a pc hooked up via usb to adjust everything. Its the geek factor in me and prolly most of us that something like an active crossover / bi-amp setup really apeals to.
