I got the dual 2 ohm and wired it in series, I wanted to present a 4 ohm load to the amp (I originally planned on a Zapco Reference 1100.1 before I got the 1000/1 free) for max headroom and SQ. Either will work well. If you ever wanted to add another sub, you're better off with dual 2 ohm subs, if you plan for just a single sub, then either will work well.
Ah i see. OK. Since my car is pretty small i going to use only 1 sub. Thanks
