To answer your question - no fvcking way bro - your kidding yourself. I bet the 15" HCCA could barely hang with or 2 15"CVR's , now your talking 4 times the cone area and a really inefficient sub that barely moves with 2k on it, vs 4 15" that are near xmax at 500 watts.
You have 2 15" CVRs / are they ported??
That would be the first thing to consider. and you have 2k - from what amp???
I suggest a AQ 18" HDC on 3.5k in place of your 2 CVR's. Type R might get louder but the CVR are gonna sound better.
