Recently bought a Crest CA-6 for home subwoofer duties. Rated 1500W @ 4 ohms bridged. That can draw nearly 15 amps from the outlet momentarily. Much of that rating is only momentary, depending on capacitor storage. At the "pro" level, seems that most most bass players prefer heavier A/B or H class amps to lightweight class D amps at similar ratings. There are exceptions like the Crown K1/K2 which have linear power supplies but have that "sleep mode" modification for home use. Seen some new class D pro amps rated at 10,000W, however, maybe not into 2 ohms.
SMPS/PWM amps have also, historically, had the issue of repairabilty because of so much integration and timing in the circuits. Can't just replace a component without dramatically affecting others.
Crest CA series has .775V input sensitivity. Can you live with a fan?
