I usually don't do reviews much, but I had to do one for this amp! This is a lil power house and very clean too! When I installed it I left the settings on deck the same. Boy I had to make some changes. The amp is so powerful and clean I could turn it up more than the old one with more power! If you are looking for a new amp and you want the very best for your money? This amp will amaze you! There is no doubt you should buy this amp!
Purchased the 350.2, 400.4. Using the 400.4 on 2 satori mids (one per door) and 2-hertz coax in the dash. (All active with dsp) All the power and more. Time, doesnt matter. From a 3 hour drive, running the system full rip, the board doesnt get hot at all, not matter how long. The connections (pos/neg, speaker terminals) are super nice. Small footprint for the power. They look great if you are into that, and also, using my Umik, i see full band width (something many class D, dont/wont give you) and the price, is amazing for what you get. Time will tell on longevity, but atm, i have zero fear(s).
Happy listening all.
(Also, I am also using knu 4-guage, like the reviewer below, and it fit perfectly. Dont know whats going on there. But it fit perfectly for me)
I'm using it with 2 crescendo mezzo sq2 components in my front doors. I doubt anyone could tell this is a D class amplifier. Maaaybe there was a side by side comparison. I used to be a rockford fosgate guy but for the price, power and sound quality this can't be beat.
Seems like a great amp but couldnt install it because my knuconceptz 4 gauge wire doesnt fit and I dont want to rewire my trunk to install it. Cant comment on performance but its a tiny but heavy amplifier. Sucks about the wiring part. Bummer
I have not had it installed yet. May be a couple of months before I actually get to use it.
