Infinity Kappa Five - short review

Got this 5 channel amp installed, and after playing around with it for a few days, I can say nothing but positive things about it.

Set up as follows.
Front Massive Audio CK6V components
Rear Pioneer TS-D1702R coaxials
12" Kicker 10CVR124

I have ran the amp pretty hard for an extended period of time, and have had no issues.
The amp can get a little warm (Not hot), but what amp doesn't heat up a bit.
I am sending out 50 watts rms to the front/rear and it's more than enough, and I have my levels set fairly low for those channels. Sending 300 watts rms to the subwoofer channel, and I decided to up the level on that channel a bit, just to get a bit more bass.

I love the size of his amp, under 15" in length. If you are looking for a 5 channel amp that you need to tuck away somewhere, this one is ideal.

Short review, and not incredibly specific, but I am digging the amp. Would highly recommend, and if you shop around you can find it at a great price.

I had completely forgotten this amp....good to see you like it bro

300watts can still produce respectable bass for my taste given sufficient cone area. However, I'd set gains with a DMM on subwoofer channel (liberally, with a -5dB test tone) to make sure you don't clip the signal.

haha, I say it like that because my 10th grade year in high school when I decided I wanted a system, this was one of the first amps I came across. I knew Infinity was legit and I liked the ease of a 5 channel. I came VERY close to buying one and just letting things be with a nice 12 and some comps.... then I got ****** into the never ending cycle of buying tons of new audio equipment and wanting to get better and better :crap:

Being a Class D amplifier, if it has efficiency comparable to other modern 5-channel amps (e.g. Polk D5000.5), I'd say the fusing of 80A indicates that this amplifier is slightly underrated, maybe by 25%. The polk has 80A fusing, and has rating of about 75watts rpms (4ohm) on full range channel and 400watts for the sub.

Good stuff, Zako.

Just to update. This amp died ten days after install and had to be returned.

did you get another or go with something else?

I have seen other reports of these Infinity amps dying. Maybe it's the reason they're not so popular. If you want a small budget class D 5-channel amplifier, I'd suggest to look at Polk D5000.5 or Alpine MRX-V70. These have been tested and verified to provide good clean signal. I haven't heard of problem reports with them on forums. Infinity is no longer a high end brand IMO. The only their car-fi equipment I like and currently use is the Kappa 120.9w subwoofer.

Zako, that's too funny. I ended up ordering a Polk PA D5000.5 earlier last week. Have had it running for about three days, everything is all good so far.
