I have had good luck with my Dayton 250 plate amp that powers my THTLP. I built separate plywood boxes for my plate amps with hole saw vents, painted them and mounted them either to the wall or back side of entertainment center out of site but easy to reach the controls. If one 250 amp doesn't do it with 150 watts at 8 ohm, get two amps one for each 4 ohm woofer or get a Dayton 500. I have also heard good things about the Bash 300 and 500 plate amps. The Yung 500w plate amp is on sale on PE right now, I run a Yung 300SD for my TT and it sounds great, doesn't get hot. The Crown 1000 watt amp is on sale also.
Another option is to build another 24" THT with a single DVC15 and run all three of the subwoofer dual voice coils in series (16 ohms) but wire all three subwoofers together in parallel to get 5.3 ohms and run them with a single amp. This may help with room nodes but you lose the ability to adjust phase between subwoofer boxes by running them all off one amp. If you have the floor space to move these around, not a big deal.
If it were me I would buy one plate amp, if it is not enough, get another, or return the first to get a bigger one.
