2 Ssd 12"'s amp question and enclosure

[tornadomaniac 0]

Hey how are yal, I'm getting 2 ssd 12's with flatwind coils and i have done allot of research on amps and im still stuck. I know the CEA compliant brands and such and how to wire them as i studied electrical engineering. Are certain brands IE sundown, Audioque better for certain subs such as the ssd. i really just need to know best bang for my buck and how many watts, should i just double the rms and how low can i go and still get the needed performance. Second question i am using Microstation to design my box i have kinda a weird situation with my truck i am going to build the box to fit over the back seat in the middle and extend to the floor it will be vented, how many cubes would be a happy medium for my space restraint.

Thanks happy posting
