Reply to Connecting Multiple Speakers/Subs

Im using a Numark Mixdeck, two powered subs (1 EV, 1 JBL), two powered tops, two unpowered Peavey SP15, and a QSC amp.

Whe I run my tops thru my subs, the side with the EV sub is great, but the side with the JBL sub I can barely hear anything, especially out of the Top. I will post a pic in a sec. I must have something connected wrong, or the EV is whipping the JBL ass.

Please help
