3 perfect 10.1d with a jbl 1200.1?

definitely, and should sound awesome

Yea those are gonna hit really hard.  It's gonna be a 2.67 ohm load but that should be close enough to 2 ohms for the JBL to put out its maximum power.  Of course if you had 4 of these subs it would be exactly a 2 ohm load but I think 3 will be loud enough for you

oh no, duh those are 2 ohm speakers!

i feel stupid!

I've heard these amps can actually go lower than 1 ohm if they get enough ventilation. I've never done it myself but supposedly it can be done.  With that being said, if for some reason you're not getting enough output when they're wired up for the 2.67 ohm load, you can parallel all the voice coils and all the subs for a 0.666667 ohm load.  Obviously if you decided to do that you should exercise extreme caution!!!!

but I really don't think you'll be unhappy with the amount of output when they're safely hooked up to the 2.67 ohm load so that's the best way to go.
