Looking for advice on Bass Shakers

I want to add a bass shaker to my seating. Which amp out of these would be best? I'm looking at either Dayton BST-1 or Aura AST-2B-4 Pro for the shaker. Unsure which to use because people say the Auras seem to have more shake to them but the Daytons are rated to dig deeper but the mini amps I've looked at are rated to cut off at 20 anyway.

The amps I'm looking at are the Fosi Audio M04 Subwoofer Amplifier and Nobsound G2 Subwoofer Power Amplifier.

Any advice on which of these products would be best for a moderate home theater setup would be appreciated.
