So it is my understanding that the MS-8 only understands 2 subwoofer outputs- those of you that have the 8" "subs" under the seat, AND subs in the trunk.. how did you configure them? Or is this incorrect? I could always pass the trunk subs straight through but would rather use the MS-8 for them as well of possible.

System is:
Stock HU
DLS 4"+tweets, active (for now, might change my mind and go passive)
8" kicker subs under seat
2- 12" JL subs in trunk.
MS-8, JL 900/5 and a 600/6 if I stay active.

I have all the equipment, and about to start installing and stumbled into some of these potential MS8 issues.

The "standard" configuration for the D9x is to ditch the rears or run them in parallel with the rear sides, so you have 2 channels on the front mid/highs, 2 channels on the underseats, 2 channels on the rear/sides, one channel for the center, and one channel for the sub. Equals 8 channels.

Maybe go passive between your mids and highs and add a center to make the most of the ms8.

The underseats arent normally considered subs. A woofer and a subwoofer are not the same

Correct, I will probably learn more when I actually get the MS8 turned on. I scrapped the rear fill.

Also, I didn't make clear, the underseats are set up as woofers, not subs, part of a "two way" front stage, with a passive crossover between the mid and tweeter.
