I know this site has sections on various ohm load situations, but this is a special case I haven't seen a solution to. I'm installing a system in my cousin's car and he doesn't really care too much about perfect sound quality, he just wants it loud. To cover the low frequencies I am thinking that more cone surface will do the job better than mega powered subs. So I suggested hooking up up four 10" 200 watt rms subs (coustic) to one 800 watt rms monoblock amp(800 @ 2 ohms, one amp for $ reasons). The subs come in SVC and DVC all coils are 4 ohm. The way I figure it, to get a 2 ohm load I need to get the dvc models and wire each unit in series then paralell all four to one chanel (see below and please excuse the crappy image). Yes I realize this is rather exotic wiring (a variation of series/parallel i guess), but is this right or am I off?

If quiters never win, and winners never quit, who the heck came up with the idea that you should quit while your ahead?

No I think you have it correctly. Each sub's two voice coils will be hooked up together in series, effectively giving each sub an 8 ohm impedence. And four 8-ohm subs wired up in parallel will present a single 2-ohm load to the amplifier.
OR, if they are the single VC models at 4 ohms, you'd have to wire two speakers in series, and then the two sets of series speakers in parallel to the amp.
