Hey guys, im in the market for a new/used amp to power my sub. I've always been a fan of the older amps & was looking at some used PPI pc or an Orion "the beast" amp. Im only have a 12" eclipse 8812 right now & may upgrade to a Tc sounds 2000 later on so insane wattage isnt a huge concern to me. I've never heard a class d amp but after reading some stories online, alot of them seem to say they prefer a good a/b amp to a class d. If anyone has any experience with both, I would love to hear some feedback. Size of the amp really isnt a huge concern, but if installing a 1000w a/b amp is going to be a huge drain on my electrical system, then I may have to take a serious look into a more effecient design.
