  • Runs cool and rms power is legit.
Style: SXE-4000.4D/BK
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. ... show more

  • This amp has power!
Style: SXE-4000.4D/BK
I am currently running 10 speakers on this amp and it is powerful, makes the voice speakers sound louder than stock and also the ds18 speakers are clear as day, so i do recommend ordering this amplifier for your future build.

  • Lasted 1 week
Style: SXE-4000.4D/BK
Bought a full ds18 system for doors and the amp. Sounded so loud and absolutely amazing after a 2 day install. The amp decided to nearly create a fire hazard in my vehicle when it nearly blew up and blew 4 door speakers when it blew. Not sure how but not going back to this brand unfortunately. Returned it and went with another brand. ... show more

  • Amplifier is for audio, not subwoofers:(
Style: SXE-4000.4D/BK
Amplifier works as it should and expected it to, but I didn’t notice that it wasn’t meant for subwoofers nor have any bass boost knobs on it and I regret buying it for that very reason. Can’t believe I spent $311 on an amplifier that’s audio or Twitter only or loudspeakers, etc.
