Thanks.  The feet are pieces of a chrome curtain rod chopped up with a cut-off wheel.  Danny recommended the amp, it is a Yung SD300-6.  300 watts at 4 ohms.  The woofers are 8 ohms so I installed binding posts in both boxes so I can connect them in parallel.

That's the same amp I decided to use, both for the single driver amps (X-Sub) and a couple pf dual driver variants. It has the 6dB boost @ 30Hz Danny recommended, will provide the minimum 150 watts into 8 ohms for the single drover subs and 300 watts into 4 ohms for the dual driver versions.
