this amp is an undercover killer it may look small but it packs alot power It's as loud as my friend's 1600 watt hifonics amplifier. I have this monster on two 12" kenwood subwoofers and my car feels like its falling apart I'm constantly setting off car alarms excelent amp
This amp is clean and efficient. Stays cool. A good tip for anyone... A gain is designed to match your head units volume, not turn all the way up and clip the amps output.
The design is fairly clean overall. Connections are made by removing the fascia shield via the 2 allen head screws allowing access to the terminal strips for connections. The first thing I noticed is the weight. This amp is light. Meaning, there can't be that much inside for a clean performer. Sure enough, this is a plane jane stripped down amp, with limited MOSFETS. CEA 2006 rating is 1% THD. Meaning it's a Loose noise monster. Kenwood rates them at 0.5% THD Secondly...Where's the second power transformer... There sure isn't one on the board. Lastly, do the math. 40A fuse X 13.8V = ~552W peak load before the fuse pops. Generally, this formula works for class AB the best. Digital amps are more efficient. Based on the number of Mosfets...there's no way this amp is getting near 800 or 1200 watts. This looks like a revised layout from the older KAC series amplifiers, with near identical componentry. There is so much sparce space on this amplifier board, there's no reason to have the heat sink this large. The other thing I observed... is the solder joints on the MOSFETS on the amplifier side of the board looked relatively poor and high in flux. Under high load, I would expect a failure condition. If your looking for just cheap sound reinforcement and not worried about quality, then pick this one up. If your looking for Better Regulated, true digital class D, and better overall circuitry...look on to either Xtant (before their MTX aquisition), JL, or Directed.
