would i be better off going with a smaller speaker?

[Briggiboy33 2]

i currently own a FI SSD15 that i have in the back seat of a 2006 tundra. i dont have enough room for an optimal box so the box is currently about 2.5cuft tuned around 31hz. i have mad a ton of different box designs and i currently can not go any larger on the box so i was woundering if i would gain volume by reconing to a ssd12? any thoughts  or advice?

2 big things, it will be much easier on the sub, and it would most likely sound better. Have you tried putting the box specs into WinISD and see what kind of response you can "theoretically" get. A perfect environment is one thing, a car is completely different. What are your max demensions?

What happened to the box design we did? Are you trying to save space now or something?

first try a sealed enclosure. you could probably seal up your ported enclosure.

I vote for sealed also at that enclosure volume.
