there is no better in this case. the question should be which one should i get? and to answer that question, it depends on ur amp and if u plan on upgrading. if ur only gonna get 1, then i suggest the 2 ohm, if u plan on upgrading, then i suggest getting the 4 ohm. if u get 1 4 ohm, then u'll have to wire it 8 ohms or 2 ohms. when u get ur second, u can wire it at 4 ohms or 1 ohm. with the 2 ohm dvc subs, u can wire them to 4 or 1 with 1, and 2 or .5 with two.
