I'm building a system around an ADAU1701 2 in/4 out board. 2 of the outputs will go to RCAs for the subwoofer... I need the other 2 to split into a 4ch TPA3255 board for the full range speakers. Everything uses JST XH -2.54 3 pin connectors... what's the best + easiest way to split those connections into two? It doesn't look like the connectors can take more than one wire in each port.
