Depends on the type of crossover. If it's a 2nd order or higher, which most tweeter highpasses are, DO NOT run it without a load. 2nd order crossovers have either an inductor or a capacitor in parallel (depending on if it's a HPF or LPF), and at the crossover frequency or a multiple of the crossover frequency, this inductor will shunt it and create what is very close to a dead short to the amplifier, the only resistance being the speaker wire and the inductor or capacitor. Not something that you want to occur.
