### ⭐⭐⭐⭐⭐ Runs cool and rms power is legit.
*by L***A on 22 April 2025*

Installed this amp to 4 ds18 high power 6.5 coax speakers. Used 4ga power/grnd wires and 12ga to speakers. Mounted amp on 1/2” standoffs to help keep air around all sides and stays cool. No clipping so it should last. Only been 2 weeks but no complaints. Amp barely gets warm. Some bad reviews could be just because of incorrect installation? No issues at all.
