Two questions: I was wondering if it is ok to slightly overpower this pair of DVC subs in a small sealed box. I have an MB Quart RAA2400 amp that feeds 400w RMS x2 @ 2 ohms (maybe underrated also..) Also, since my amp feeds 400w x 2 @ 2 ohms, I can wire these DVC 4ohm subs so that my amp sees a load of 2 ohms in each channel... right? Thanks in advance!
