[QUOTE="Loren Jones, post: 2113, member: 829"] What is the best way to power 4 x 8 ohm sub cabinets (front-loaded reflex cabs each loaded with an RCF LF21N451--1500 watts rms, 3000 watts program). At the time of building them modeling suggested that an amp that could provide power in the range of 120v per cabinet would be appropriate. Cost is a factor. It would be an install so weight and power needs aren't as much of an issue. 2 "smaller" amps such as PL380's run either with one 8 ohm cab per channel or each amp bridged into two cabs at 4 ohms. 1 larger amp such as a K10 or MA9000i with 2 cabs on each channel at 4 ohms. Price wise a pair of PL380's are probably a little cheaper but less power if run in the 1 cab per channel configuration. Any real reason to avoid 4 ohms bridged operation with good quality amps?
