[QUOTE="Deiimos, post: 8897948, member: 682903"] I don’t know what subs they are, if we assume they are true 400w RMS each, I would get a class-D amplifier that does 800 to 1000w RMS at 1-ohm and set it properly. This makes it easy to wire a pair of subs with 4-ohm DVC coils in parallel, and not having to match multi-channel amp gains. The amp just needs to handle the speakers combined final load (4-ohm or 1-ohm in this case, whichever you decide on), and put out the desired power at said load. The main goal with the impedance is to not blow up an amplifier do to running too low impedance it isn’t designed for. You can certainly run a bigger mono amp that can do the 800w at 4 ohm, or use 2 or 4 channels that can do 800w or whatever. You really wouldn't notice any difference at either load with the same exact amplifier power in each scenario. Also keep in mind multichannel amps are often still class AB, so they will run much hotter and be less efficient than a class D. Although, class D has become more common in the multichannel amps these days. [/QUOTE]
