Pros & Cons

  • great overall power, and powerful, very reasonable price, lots of power, very loud
  • casing over connections, documentation is very vague, quality and installation process

The KAC-9104D Class D Mono Power amplifier cranks out mega doses of power in a much smaller chassis size (30% smaller than previous models), so it’s more adaptable to tight spaces like under seats or in trunks. The KAC-9104D also has a Dual Mono Drive connection that allows you to strap two KAC-9104D amps together to power a single subwoofer—that’s 1800 Watts of power!

  • 1800 Watts Maximum Output Power with 30% Smaller Chassis Size
  • 500 watts RMS x 1 at 4 ohms (900 w…

    Missing Attachment Kenwood has built their reputation in building car audio amplifiers which offer outstanding reliability and advanced sound quality. The KAC-9104D is a compact mono amplifier designed by Kenwood which features a rugged aluminum cast chassis that is nearly 30 percent smaller than its predecessor and it still punches out nearly 900 watts of RMS to your subwoofers without twisting the electrical system of your car.

    On the other side, your signal enters the amp through a pair of RCA inputs. Use both of them and the amp sums them together for a mono (full) signal. The signal passes through a gain control, then the lowpass crossover, and finally the infrasonic filter before going to the output stage. All of the components in the signal side are surface mount with the exception of some electrolytic capacitors, which are inserted from the other side of the PCB. Read more

    Have 2 of these hooked up to 2 12" premiers 3000 watt subs. Powers them very nicely wired to 1 ohm. I used to have 2000 watt 2 channel but these beat it by far. They are not a good as other brands of the same watts, but for half the price or more it is alot better deal. Read more

    I have this amp connected to two alpine type Rs in a sealed box wired to 1 Ohm and MAN IT MOVES AIR! The amp has not cutout once. I have 45 min commutes and has not caused any problems. It gets alittle warm but does a fine job of cooling its self. Great amp,sounds good and the price is right. I would buy another one again. Read more

    I had this hooked up to 2 alpine type r 12's at a 1ohm load and it hit so hard I removed one because I was losing my hearing. I don't know why people have a problem with the amp cutting out I have no problems whatsoever. True it is only putting out 644 watts RMS at 14.4 volts. I also have a 5 farad capacitor in use along with my setup maybe that helps, it helped my lights stop dimming. Before the capacitor when the bass hit hard at high levels it was actually shutting...
