Forgive me for this question but im not up to par with my car audio knowledge. Anyhow which of these would give me a better set up, JL Audio 12W3v2-D2 or the JL Audio 12W3v2-D4 with the JL Audio 1000/1 amp. I know I want that amp but im not sure which sub I would get the best results from as far as the ohm's are concerned. Thanks for the help guys..
