Congrats on your dc purchase! I just love it when people here in my small town ask if my subs are as good as kickers, jls, etc... Then i make them sit in my car. Had one guy last week that jumped out before i even turned it up good!!
And my cousins wife had two level 3 15s in a regular ported box on a 2k that got pretty loud, so i know your setup will slam good!!
