I still have this old 12cu 40hz box i made for some dd9515's when i had my blazer and was wondering if i would drop in 2 3515;s on 2 1000rms plate amps would that sound decent or would they want more power? I cant find any plate amps that do much more then that or i can do 2 amps per sub... if they make dvc 4ohm...
I don't think DD would be the best choice for home audio subs and tuning to 40 Hz for home audio would be absurd. The box should be tuned well below 30.
