what to do?
 

havent done much with my stereo for a while. wouldnt mind if my sub was abit quicker(and louder would never be a problem). so I have 2 options, what would you do?

1: leave it as is. 1 12" Clif Designs C120 dual 2 ohm. 600WRMS. wired in series(4ohm) to my Ultimate T3-1000D. sub is in a 2.5ft^3 tuned to 30hz before displacement.

2: 2 10" alpine Type R (round surrounds). wired to 4 ohms on my T31000D. both in 1.5ft^3 tuned to 32hz.

both options would be getting the same amount of power.
