[QUOTE="brian84corvette, post: 8305156, member: 586635"] single sub amp = ddm3a subs are dual 2 coils - wire to .66 ohm load at the amp. each sub is rated at 600w by the factory - because they are built with loose suspension - the coils can take 1k rms power - but the suspension is so soft that they dont need that much power to reach full throw in and out - and are limited by the voice coils ability to move so far in and out that it hitts the inside of the motor at full x max on the rearward swing. because suspension is so soft = efficency build - and small box requirments.... each 18 only wants 2.5 to 3.0 cubes net on the sealed side of things to keep mechanical throw of the sub in check... its an experement of large scale. efficency is my goal. do the most with the least... in my case - the least is power. wattage / electrical i see no need to feed a super stiff sub 3k to get the same amount of cone movment as the soft subs i have that only need 600w to do the same thing.
