In YOUR case, the Jehnert is a bit more efficient, but not quite as much as the CDT so you could go either way (bridged or single channel).
Yeah I tried it both ways on mine. I don't know if its because they are under the seats, but they did sound better bridged.

I also have them bumped a bit thru the processor.

Ok it's sounds really good now..
I'm still getting the very low end buzz when cranking it up.
I figure I need to,
A...add an MS-8 and tune subsonic levels to the underseats
B...buy 2 bass blockers to block out anything under 50hz
I'm still buying a corner sub enclosure with a jl audio 10w6
Probably power it with a jl audio 600/1
What's everyone usual next step

Do you still have channels 5-6 bridged, powering both underseats?

No, CH 1-2 is for the morel ovation hybrids, CH 3-4 is for the stock rears, CH 5-6 is for the kicker ssmb's
