so did you get it working???
you do have the basic fade and balance
+1 on reading instruction manuals
if its still not working try swapping rca/av cables from speaker amp to sub amp ... and if you are you using constant wire for your remote you might want to swap it to a acc wire (how are you going to turn the amps off??)
since your remote wire is screwd maybe you deck is screwd in some way (idk)
bad rca's
