Self-interacting dark matter resolves the issue of cuspy profiles that appear in noninteracting cold dark matter simulations; it may additionally resolve the so-called "too big to fail" problem in structure formation. Asymmetric dark matter provides a natural explanation of the comparable densities of baryonic matter and dark matter. In this paper, we discuss unique indirect detection signals produced by a minimal model of self-interacting asymmetric scalar dark matter. Through the formation of dark matter bound states, a dark force mediator particle may be emitted; the decay of this particle may produce an observable signal. We estimate the produced signal and explicitly demonstrate parameters for which the signal exceeds current observations.
