will one of these be suitable for a u shaped sectional couch? Each sectional (5 pieces) is attached by only a metal linkage.

In your case, in all probability, only the section that the Buttkicker is mounted to will experience any significant shaking since you need a really SOLID mechanical connection between the Buttkicker and the sofa, and between the sections to transmit the vibrations. It would be a good idea to check out some of the YouTube videos on mounting Buttkickers to sofas/chairs. BTW, I recommend mounting the Buttkicker to the frame of the sofa, rather than using the Under-leg Mounting Kit. The reason is that when the device is mounted to the frame of the sofa, you get forces transmitted to the structure on both the upward and downward strokes of the Buttkicker internal piston, whereas when you use the under-leg mounting method, the Buttkicker is driving its force into the floor with little motion for half of each cycle.

How many of these bad boys do I need to power a row of 4 home theater seats? 4? Or can I get away with 2?

As long as the seats are attached solid you would be fine with 2 BK-LFE. You would also require an amplifier to power them.

What is the best amp for this. Try to be spacific.

I called and talked with ButtKicker, they said the Dayton SA-1000 was the best and was equal to thwir amps. There is a company called Partsexpress.com with the best price, 398.00

Where would you mount this in a car? Also how would you mount this to a car?

Typically in the trunk. It's too tall for anywhere else. But it's not your best choice for a car anyhow; this thing requires a LOT of power. It's moving a big piston. And it's heavy, while you want your car light for performance. An Aurasound or Clark Synthesis transducer is smaller, easier to mount to your seat's underside and more power-efficient. They won't -thump- as much, but they're better choices.
