this amps is completly nasty in every aspect. I recently bought one and i think in my opinon they sound better than the jl 300/4 slash series amps w im not knocking any amps ive been a jl consumer for many years ive owend all there slash series amp at one point.but whats different that i like is first it can do six channels vs four and these amps are unregulated power supply which means if u have enough power they will sound louder.and i can power my center channel front and rear speakers from on amp vs two amps saves on weight and current draw in the vechile.there a great buy for the money when i first bough my 300/4 amps they were 600 dollars each.and the amps sound identical in sound quality tested the higs on a real time anilizer meter and the results were the same quality . I also tested for distortion using a pink and white noise microphone and they tested almost identical.so in my opinion the human ear could not tell the difference
