i recently picked up a DD9515f dual 0.7 and "retired" my MOJO.

i am using an oldschool earthquake amp (phd3) to power it (http://audioforum.termpro.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=20;t=012598;p=0). in a 4^ft3 @ 31hz box.

i have it wired in parallel. turned the gain up just a hair pass 1/4. and the sub was like popping. i am running 1/0 wire all the way back. voltage was low-mid 13(have not done the big 3 nor installed my kinetik 2400 due to a blizzard we just had)

is there something wrong with the sub? the box? the amp? what could the problem be? i was testing it out burping and these are supposed to be rated at 6000max. this is my first DD, and im starting to think i might want the mojo back in.

 
threw the 2400 in the trunk and the problem is solved! voltage barely drops and the sub quiting popping and now just sound A LOT louder than the MOJO. not to mention the amp didnt warm up at all
