Yo, so me and the gf are about to expand our movie watching experience by getting some better sound going and as it's the first time ever im buying something like this some help would be greatly appreciated!\n\nOkay so i've seen lots of videos about this stuff by now but it's still a little confusing, or there's 1 thing im thinking about right now and thats the wattage required or rms on the receiver i guess.\nI've been looking at the Yamaha RX-A4A and the Denon AVC-X3700h(is this even the new updated version without the 2.1 hdmi bug or is that the AVR-X3700h? this ones also confusing so ive primarily been looking at the Yamaha but open for suggestions)\nI currently have a Klipsch RP-504c that i bought off a friend when he was moving and it says that one requires 150w continuous power, then i plan on buying 2x RP-600m later on as front L\/R and then probably another pair as back L\/R and those require 100w cont. each if im not mistaken?\n\nThat's 150w+400w so 550w overall and it says this Yamaha can only do 110w with 2 channels driven? There's no way i'd be able to run that with this receiver or am i confusing myself? Oh and i'll probably add 4 atmos in-ceiling ones down the line aswell so that's even more power required but im pretty sure i'll need an external amp for those last 2 inputs anyway right? Reading on crutchfield that the receiver only powers 7 but has 9 outputs so im just guessing here, if it even works.\n\nThat's pretty much it. Im buying the SVS PB-1000 Pro aswell when i buy the receiver i think as i've seen it's being recommended almost anywhere i look so it should be good, and it's an active sub so it doesnt matter how much the receiver can output right?\n\nTLDR\nbasically what im asking is would a mix of these work without issues, is the receiver powerful enough to power all of this or do i need something extra too. For now i only have the center and will buy the sub with the receiver. Front\/Back L\/R come later. Atmos much later.\nYamaha RX-A4A or Denon AVC\/R-X3700H\nKlipsch RP-504c\nKlipsch RP-600m x4\nSVS PB-1000 Pro\n2-4 Atmos speakers\n\nAny answers would be cool and i thank you for it.\nIf there's some other issues with this that i've glanced over feel free to correct\/point it out to me, Cheers!
