Review: Sounds great! - Amp I great! We added additional speakers to the bed of our 2023 Jeep Gladiator and needed more power. No issues so far with any of the DS18 products we have bought and installed. Great quality!
Review: Runs cool and rms power is legit. - 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.
