Default 3 Subs, 2 Amps Strapped. Which coils to get?

I'm gonna be doing a build at the end of this year, gonna be 3 subs 15/18's and 2 big amps strapped. Wondering what coils would be best to get, the amps are .5 stable, probably a little bit lower than that. I would like to have each amp seeing around .5 strapped at 1 total. Dual .7's? Dual 1's? Dual 1.4's? Dual 2's?

Confusing myself calculating everything...

if you got dual 2s you could get .67 on each amp. with dual 1.4s i imagine that would put you around .5 or less on each

http://www.mobileinformationlabs.com...iring-1%20.htm using this calculator i put in the resistance then put 1.5 for the speakers. it runs it just fine and accurately it seems

D4's would get you .66
D2's would get you .33
D1.4's would get you 1
D.7's would get you .5

I'd go with .7s

I have tested that amp about a bazillion times. I know what it does clean, clipped, dirty, loaded, unloaded, wired down, low voltage, good voltage, after it hot, while it's cool, on caps, on batts, where it protects, what's thermal limits are and just about anything else anyone would care to know about it.

But thanks for chiming in. Your opinion is duly noted.

You 100% on this? And are these strapped loads or each amp?

Well first of all there's multiple ways to wire so giving one answer to every coil is incorrect. I was just giving you the closest to what you wanted. Series, series/parralel, and parralel series will give you different loads.
