We haven't played a larger venue that doesn't have house sound, so I'm trying to fill the room with what we have, so this question arose. We would like to run our 4 JRX125s as mains, pairing them on each side for stereo sound. Typically we only use 2. Will splitting the signal with a y-cable from the board to the power amps effect signal or cause issues? Ex: L output to split both "L inputs" on amps. R output split to both "R inputs" on amps.
