DD3515 dual 2ohm

[thecat666]

well im the proud owner of one of these DD3515 dual 2ohm, i have about 40.5 inches width 14 inches deph 16 inches height external 1inch all round 2 inch baffle roughly 4.45cft with out speaker displacement. not sure on what the best tuning for dd3515 is in that size cab,i have the chance to get one of these amps Rockford 500bd

taken from a thread,From memory the birthsheet said something like 740W into 2ohms and 76% efficiency

It's rated into 2 ohms, but I have run it at 1 ohm as have many others with no problems can any one confirm this amp would run 1ohm.if it can be run at 1ohm then what output would i hope to achieve from the amp? i will have to wait until i can afford 1 to 1.5k maybe 2k amp. i also have earthquake pa2150 1x700 rms 4ohm does any one no if its class a b or not.lets say i have min of 740 rms and the above space to play with what sort of db would i hope to get from that power? my current set up is sql now i want to play with something different want to be able to swap cabs when feeling like some really low powerfull hard hitting bass.i would like to achieve 140 db plus on music really loud really low what would you guys recommend

nobody knows what kinda DB youd put up, those DD love port area so your box is on the small side for what you have power wise.
