2 or 3 SD 8s

So I just picked up a new saz1200d and a pair of sd8s from ssastore on their black Friday sale for my new car, 2014 focus st, and now I'm considering ordering a third and running 3 @.66 ohms so about 400 watts a piece. I'm going to run them at .25 cubes sealed each. What do you guys think? Get the 3rd?

i'd get the third... it all depends on what your going for though, I just came off a single 12 hdc4 to two 8's, AB XD 8's and the 8's are beautiful, clean, yet hit the lows... tuned to 32.... but it is definitely not a 12 !!! lol but these XD's are louder than my sa8v1's so you will probably want the 3rd....

I want some decent output while keeping most of the cargo space in my hatch. I would have gotten sa8v2s but they are too deep and need too much space for my goal.

.35 would be bettter than .25

and that 1200d will make 1800w at .5 so thats alot of power for 3 8s 600w each isnt that double rms

Well three d4s in parallel is .66 so I figured around 1500 out of the amp possible and knowing sundown's 8's, I've played alot with the e8v1s and v2s, I assumed that the sds were rated very conservative and could probably handle 500 or so as long as I was easy on the gains and didn't push them too hard. I could potentially do 4 of them and run them in parallel for a true .5ohm load. I'm not sure if I'm ready to upgrade my electrical too much yet. I plan on big 3 and maybe new battery before install, my car does come with a 150 amp alternator.

go for three that amp will never see a .66ohm load while playing so you should be good to go.

Yea that was what I was leaning towards thanks, and one more cone is going to give me a decent amount of extra output

But thats not exactly true during music it is very possible for the ohm load to drop below .66. Really in this case both the amp and the subs should handle fine
