I'm just stuck. Can't figure out 2 12" DC Level 5 m2 D1 with a DC audio 7.5k @ 1 ohm vs 2 12" Sundown Nightshade v.3 @ 1 ohm DVC on a DC audio 5k. What would you guys think? I see that both have good SPL and SQ, so that really just leaves, in my book, the wattage. Not sure how much 500 watts can...
