Yes, it's a weird matchup: old school Kicker Freeair F8a vs old school JL 12w0
Kicker F8a spec sheet
Here's the situation- I have both of these drivers hanging out in my garage. I'm planning to build a box into the unused space under the floor of my wife's Mazda 5. Based on some rough measurements, I think I have about 1 cuft to work with. The goal is to build a subwoofer into her car while buying as little as possible.
I modeled a few enclosures in WinISD, and was wondering if I could get opinions/feedback on the graphs. The SPL lines are based on 220w input (JL e2150 bridged mono).
Cyan = Kicker F8a recommended large box, .78 cuft, 36 Hz
Yellow = Kicker F8a 1 cuft, 42 Hz (seemed to be the best curve)
Red = JL 12w0 1 cuft sealed
Green = JL 12w0 1 cuft, 35 Hz
Orange = JL 12w0 recommended ported box, 2.5 cuft, 28.5 Hz

1. Can that F8a really get as loud as the 12w0? It only looks to be a dB and a half away at max. I realize that the F8a won't go anywhere near as low, but it seems to ride right on top of the 12w0 sealed box curve's low end dropoff.
2. Is 220w in a ported box too much for the 12w0? It's only rated for 125, and my amp probably puts out more than its 220 rating.
3. Are these "boxes" too small for the 12w0, considering that JL seems to recommend smaller than ideal enclosures, and their recommendations are all larger than the space I have available?
4. Anyone had experience with this super old Kicker Freeair? I know mine powers up and moves smoothly, but I haven't heard it in a box.
Thanks for any input!
