thinking about buying these 2 sundown zv3 18s to replace my 2 fi ssd 18, would i be gaining or loosing, i got a mmats 3500.1 for da power

i didnt contact fi, but the subs do say ssd for sure the smaller motor one has ssd bp 2ohm, and the ufo motor shape one has ssd, my friend put a meter on them and they both read 2 ohm, so im going to try it and see what happens

test fitting the box in my car

well after looking some more, i found ssd d2 written in both, but the newer one has bd written in it also, but look identical on the inside with copper coils,

i bought some ssd 18s used how can i tell if they have the high qts option, and if i had a fully upgraded sub whats will be the rms and max watts of the sub?

ok so i took a flashlight and look inside the little holes and seen ssd d2 written on the inside, but the other one i have has a different motor any ideas, is this one a different or newer one?

i bought these 18 subs from a dude i know but im not sure which ones they are, i cant find a product # on them any help?
