5.0 out of 5 stars traded old amp a while ago... ended up buying again, May 1, 2008

By	Donovan Flannery (michigan) - See all my reviews

i love this amp, never gets hot, real small, high output... i owned this awhile ago but traded my whole setup, and im back again. my previous kac-x10d had screws which would not fit the allen wrench they supplied you with but no big dael i had plenty of tools to fix that issue.

4.0 out of 5 stars amazing sound quality, January 7, 2008

By	J. Flannery (michigan) - See all my reviews (REAL NAME)

comparing to my old amp, everything hits harder and strong with this amp. previously the bass would kinda rumble with my old amp but with this in place with the same subs its amazing. it never even warms up even with heavy use like my old one, when you touch the amp its cool to the touch. the only thing i dont like about it which is only 1 problem is that the allen wrench they supply you with does not fit the allen screws which hold the cover plate on its like a size under for what you need. <- which is no big deal because it still works, although my bass makes the screws rattle up and out of the amp because i cant tighten them down as hard as i'd like to.

by the way this amp had enough power to unbolt my chimsel lamp and bounce it all around on the back window. <- my solution... threadlock

2.0 out of 5 stars Digital? Where?, May 23, 2008

By	CG (Michigan, USA) - See all my reviews

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.

Here's the specs:
Class D Mono Power Amplifier
K-STAT technology
Dual sigma drive
Dual power supply with two transformers
Maximum Output Power: 1200 Watts
RMS Power 4-Ohm: 300 Watts x 1 (20-200Hz, 0.5%THD)
RMS Power 2-Ohm: 600 Watts x 1 (100Hz, 0.5%THD)
RMS Power 1-Ohm: Over 600 Watts x 1
Signal To Noise Ratio: 80dBA (Ref:1 Watt into 4Ohm)
Infrasonic Filter: 15Hz, 25Hz, -24dB/oct
Bass Bosost ready (Wire remote): 40Hz-100Hz, 0dB-+18dB
Low Pass Filter: 40-200Hz (Variable), -24dB/oct

OK... Now for the truth.
CEA 2006 rating is 1% THD. Meaning it's a Loose noise monster.
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.
