if your goal is affordable, then stick with a single woofer setup. The size depends on how much room you have and whether you want to go sealed or ported.

If you are on a tighter budget, I would go for the Mach 5 or Fi SSd (or DC, not sure how much that one costs). You will probably be happy with either and they will save you some money compared to the others, which you can then put into a better amp or electrical upgrades

Alrite than I think I'm going to go with a single Fi ssd15 or ssd18 than, and come back and upgrade with another, I think these are the perfect speakers and are extremely affordably, few last questions is it worth it to pile on the upgrades flatwindcoil,

coppercoil, BP power and what ohm selection should I use? Also where can I look up some recommended box dimensions for the sub?

that should answer most of your questions. if you're wiring the sub down to 1 ohm, you want the dual 2ohm coils, anyone please correct me if im wrong
