What sub set up would you choose

[Gomezd79]

I currently have a JL system which has C5,C2 components powered by XD 400 amp. A HD 1200 amp powering 2 12w6v3's in a ported box. So I am going to do the big 3 and alt upgrade next week. I want to upgrade and add another HD 1200 amp. My question is in everyone's opinion what would you pick out of 4 12w6's, or 2 13w7's, or 2 Hertz SPL SHOW 15's? I have heard hi energy 12's but not better than my w6's. I also can't find a shop locally that will demo a 13w7 or a spl show 15. The car is a 2016 Scion iM. The shop I went to said there is plenty of room for either set up I go with. So which sub set up would you pick? Any advice from people who have heard all three or just the Herts spl shows would be great! Thanks

That depends on your goals. If you can get the full 1200 rms from each amp then neither sub will take the power for long periods of time

Id get 2 sundown X 12s... Jl is nice but way over priced if buying new.

Ok thanks. But out of the three set ups I mentioned which would hit lowest and deepest? And which would you guys do of those set ups? I recently heard DD's in 2 different cars and set ups. They shook the **** out of everything but neither DD system sounded as quality as mine. Lots of rattle but no quality at all compared to The JL I have. I will say though I heard a system with 8's and a system with 12's and the DD 8's were about as loud as my 12w6's.
