drop to .5 ohm or strap another one?

So the deal is im running 2 sa-12s on a lanzar optidrive 3201 and my infinity kappas off a jl 300/4 v4. My electrical is starting to fall short after adding the JL. I have a d3400 under the hood and a khc2000 in the trunk. big three and one run of 1/0. Im getting quotes for a h/o and im looking at 350 for 240 amp or 400 for a 270 amp. Anyway, the sundowns are nice but im looking for a bit more. The lanzar says it .5 ohm stable and does 3200wrms. My other idea is buying another opti3201 and strap a pair of them at 1ohm for a total of 4200wrms. My question is what is going to be less taxing on my electrical and if I do buy another opti, would the 240 amp alt be enough? or should I go for the 270. What pair of 12's would sound good on 3-4k in 4ish cu ft at 29 hz?

well if you run them strappped at 1ohm they will each be running at .5- so that will be much wworse

Im sorry, to clarify what i ment is that they will be strapped for a final impedance of 1 ohm. Each amp would be running at 1 ohm. 2100 @ 1 ohm x 2 = 4200

no bro

2 amps strapped at 1 ohm will give a final load of 2 ohms so 4200rms at 2 ohms

2 ohms strapped at 0.5 ohms will give a final load of 1 ohm so about 5000+ rms at 1 ohm

but 2 amps strapped seeing 1 ohm= 2 amps running at .5.

Yes, sorry I understand now. Im tired lol //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gifnonetheless, running at 1ohm strapped for 4200 @ 2ohms or just running one amp at .5 ohms for 3200, my question is will my current electrical setup plus a 240 amp alt from mechman support that or would the extra 50 bucks for a 270 amp be absolutely necessary? Also what subs perform well at that power in 4cuft?

Any of the big boy 3 inch coils, nightshade, death penalty, Z3, level 4, HDC3, etc, etc ,etc. You have alot of options in the 300-500 price range depending new or used, etc.
