I was almost dead set on IDmax subs, but then I went to a local store, and found DD subs. I was impressed with the way they were built, how stiff they were, and how much power the could handle. Now my question is, should I do one 12" 3500d or 2 2500a 12" subs? They will be played on my mojo amp, wich is 2400 watts. Man,I am in love with DD subs now
