I have the hybrid integra 403's in the back. The GB12's are nice, but there is a little issue I am having with output from them right now, not quite sure where the issue is yet. I am using the built in DSP of the Helix amplifier, it has 8 channels in, 8 amplified channels out + 2 channels non-amplified RCA out.

So the issue I ran into with low output from the subwoofers was cancellation, I wanted to preserve as much trunk space as possible so the subwoofer box was built up against the trunk and cabin wall, speakers facing up, speaker wall butting up to the ski passthrough. To fix the issue I built a wall between the subwoofers and the rest of the trunk and it made a huge difference. I also removed the stock subwoofer and added sound deadening to the rear shelf, which also improved the sound, not so much output though, as the wall fixed that. Car sounds fantastic now that it is completely finished and tuned. I figured I would put an update in case someone ran into a similar issue with subwoofer placement.
