Anyone know if this can safely run 4 ohm speakers like the Masterclass 2504?

CarlitoBased on the specs, it appears so. Here is the on-board chip use in this amplifier (TPA3121D2) specs below:
"The TPA3121D2 is a 15-W (per channel), efficient, class-D audio power amplifier for driving stereo speakers in a single-ended configuration or a mono speaker in a bridge-tied-load configuration. The TPA3121D2 can drive stereo speakers as low as 4 Ω. The efficiency of the TPA3121D2 eliminates the need for an external heat sink when playing music....
...The patented start-up and shutdown sequences minimize pop noise in the speakers without additional circuitry."
The chips power specs, and load ranger are given "10-W/Ch Stereo Into an 8-Ω Load From a 24-V Supply 15-W/Ch Stereo Into a 4-Ω Load from a 22-V Supply 30-W/Ch Mono Into an 8-Ω Load from a 22-V Supply Operates From 10 V to 26 V"
