Super nice amp needs more attention for how good it is!!

When I bought this amp I couldn't find any reviews or bench tests I just went with the description hoping it wasn't like a crunch or lazar kind of amp that says 1100maxxx like the more x's mean more power. I have it running a set of 6.5 component speakers on 1&2 channel and two 12s Kenwood KFC low rms subs in a sealed box in my 13 Hyundai Veloster. This was the perfect amp for that, its crystal clear highs and mid on the components and bangs on the subs, when I play music 3/4 of the volume my rearview mirror is worthless just a jumping mess it does true rms at 125 a channel and has ton of features that you don't see on other amps and the see thru side of the amp is beautiful not so much on the top side but no one really sees it just hears it and that's what counts. I highly recommend this amp!! Trust me its not a planet audio, legacy, crunch amp its more of a pioneer or ppi kind of brand mid or higher brand. I had to but this review in because there is no reviews out there and this amp deserves attention at least thats my two cents on it!! Thanks Jimmy

update on my q4000 amp

its going on 7 months now and amp is still going good. Only issue I have had is it will get hot but its a ab amp so that comes with the territory but I also have a hour and half drive to work each way and I bump the whole way to work so I test it on the daily. If you do get this amp the better the ground you have the less heat it will run. I did blow my components speakers the renegade 6.5's the amp was just to much and I ran them with to much gain only at half gain but they screamed when the were going. I had the components on 1and2 channel and 2 Kenwood kfc 12's on 3and 4 channel I had to use a LOC on factory amp in my Hyundai Veloster with dimesion audio system. I love the amp and with my factory system which has its own subwoofer channel I used the LOC from the sub channel to my q4000 sub channels and I turned q4000 on high pass on the q4000 sub channel the amp which I can then use the low pass filter as a sub sonic filter if the signal coming from the music sources that has a crossover on low pass already which made my bass low and bump harder. I has features that cater to your needs. Thanks Jimmy from Columbus OH Go bucks beat the irish!!
