You can install a preamp on a Darkstarred bass without causing your amp to immediately catch fire?

I thought Darkstars were obscenely huge passive monsters in no need of extra active boost. Or is it more a matter of expanding the tone? (I'm also under the impression that a Darkstar has as much tonal variation as a passive PU can possibly have.) Because if you're trying to add oomph, I figure that's like spritzing a habanero pepper with Tabasco.
Forgive my ignorance on matters electronic. But I've been interested in building a Darkstarred bass, and I've wondered if it was even
conceivable to install a pre-amp along with it.
