I use a Pheonix Gold 500.4Ti with two channels running M361 components with 75x2w and one 10" M6 powered by the other two channels bridged into 2ohms (rated at 250 into 4ohms, 2ohm stable bridged but unrated). The amp being underated and running in 2ohm's bridged gets the job done quite nicely.
Sent my money for a D5600.1 for my Atlas's. 600 watts at 2 ohm. Cant wait till i get it in //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
