Default 4-layer PCB, 2 voltages, ground ??

I'd like to put (mono) amp & crossover on the same PCB, and can get 4-layer boards made. Crossover uses +/-12V (regulated); Amp PSU will have a separate bridge for each (25V) rail. My idea is to use one internal layer for 0V (shared by both supplies), and the other for signal Ground. Will this work?
