I am building a pair of 18x18x24 DPL12 based subs and am debating an Anthem MCA 2 as a sub amp (it is relatively inexpensive, and is usable for a lot of other applications). Anyone see a problem with this? Am I better off going to a pro amp (QSC or Samson S1000) or even a venerable Adcom 555 (the Adcom 5803 looks good, but pretty expensive). My main reluctance for a pro amp is the fan... never mind I wonder if a lot of the power ratings are suspect. TIA. M.
