Those are some beast. I been debating on which setup to run under my seat ported. Was thinking either 2 dd 2508Gs super charged in atleast 1.1cu net per or 2 x8 v4 in 1cu per. Or with a 2" seatlift i can run 4 sa v3 8s or U8s ported. Wanna get loud as possible and hit the lows which i like around 33hz on up not really nothing under 33hz. I know with 4 subs they would be in around .75cu net per and if i went with jus 2 beefy 8s i could put them in there maximum recommend volume. Was gonna prolly go with salt 3 since i seen them amps do well over 3k
