12V Class D amp to match Munro Sonic Egg 100's

Hello y'all,
Im building a camper-van music studio.
All powered by 12v so we don't kill batteries using an inverter.
We already have some MunroSonic Egg 100's.
I like them because they will fit nicely into the weird arc of the van roof and wont have corners to bump heads on.
The Munro amp is 240v so I want to replace it with a 12v Class D.
Can anyone recommend anything?
Really don't wanna break the bank here - I know I wont get the exact same performance as the original amp but something flat-ish response-ish just to get them going as good as possible for £150 - £350
Happy to buy a board and make my own box etc....
thanks!
