well, alrighty, then. hey, i'm on your side, i run two skar ma-8's in small ported box and i love them. on a apsm1500.
15hz below tuning...I called it. Most sub in a decent box is going to bottom out that far below tuning if you are putting anywhere close to RMS power to it.
Raise SSF, or drop the volume on notes that low.
What year civic is it? 2 or 4 door?
I have a 98 4 door and was doing 148@30 with an m3a amp and an 18.
Would do 141@19hz.

Yeah iirc you're only supposed to play around 5hz below tuning I could see trying for lower if you were under-powering them but not on that power just my .02. As for the zvx being better than nightshades I'll just sit here quietly and act like I agree.
