[QUOTE="ckunke002, post: 8038810, member: 637083"] You said "subs", making me assume you mean 2 of them but I'm not positive that's what you mean lol. So for each one of these subs, you're options are to either wire them in parallel for 2 ohms, or wired in series for 8 ohms. Now finding the amp to drive 8 ohms at those levels will be a very unnecessary task, that is a lot of resistance. What you will want to do is drive them at 2 ohms. You also mentioned powering the voice coils separately, by using a 2 channel 550w per channel @ 4 ohm amp. Again, this is asking a lot out of an amp in comparison to a mono channel amp that would simply have to put out 550w @ 2 ohms on it's one channel and you would end up spending a lot more. Essentially every amp made for subs is stable at 2 ohms, so you might as well take advantage of that and wire up as efficiently as you possibly can. If you want 1 of these subs, I would buy a monoblock amplifier that can do around 600-700 watts RMS (for wiggle room) on it's only channel at 2 ohms. If you want 2 of these subs, I would get a 1 ohm stable mono amp that can do around 1300-1400 watts RMS and wire up both DVC 4 ohm subs to the channel in parallel creating a final 1 ohm load to your amplifier.
