Hi Guys, A quick question... I just purchased 4 XTI 4000's to run in Bridged Mono on 2 JBL VRX 932's(8ohm) over 2 custom 2x18's (4ohm). When wiring with speakons, and using the internal crossover function, the manual states that the sub output comes from channel 1 (1+/2+). What do I do about the top cabs? Is this something that can be addressed with the band manager software, and if so, should I use the crossover function on the sub amps, and run the top amps in normal bridge mode then set a HPF on the tops, or is there a way to change the signal that comes from output 1 from sub to hi?
