yes the sub pre-out is on and gain is turned up as well. I love the HU but this is killing me! I ran RCA from my jl amp (has preouts) and it seemed to be louder but still sound is very low.

i'm having the same problem here!!! the seperates in the doors and behind the rear seat scream, however i can bearly hear the subs! I have the bypass done also. I know the d3's have crappy output voltage but is there a processor to compensate? what option short of getting rid of my HU do i have? FYI: HU: d3 FS amp: jl e4300 FS: infinity 6820cs all the way around. Sub stage: sundown saz 1500d subs: 2 x idq 10's duel 4's.
