I have both sets of subs the dr"s are the old 1000rms model. the box I built for the hdc3s is 12 cuft net tuned to 35, and they get loud but not much louder than my 15s in there 8cuft box tuned to 32..i was wondering if I put my 15s in that box would it be louder...the amp is a brz2100.1..do the hdcs need bigger amp or bigger box?
