Weak amp keeps turning off

Weak amp keeps turning off. Works component 6x9 kappa and 6.5. This amp keeps turning off and takes about 30 seconds to turn back on. It also takes 30 seconds to even turn on. Bad buy, I wish I had gone for a stronger one.

Pros
  • Full range line outs
Cons
  • Slightly cracked

Great amps for my boat

I have 3 of these amps on my boat driving 9 speakers. The sound quality is amazing and the amps are compact for tight spaces. The amps stay nice and cool throughout. They seem to put out over a hundred watts per channel. Great quality for these amps.

Pros
  • 100W x 4 - Class D design
Cons
  • No mold required

Good quality amplifier for portable audio and video

Lots of power in this little amp, I'm pretty sure watts per channel is underrated. The front channels work about 1/4 of the way with 100 watt speakers. Gain with excellent clarity throughout the range. Rear channels 6 1/2 inch 75 watt speakers powered by Hipass. That's also about 1/4 way gain. Nice appearance, was surprised how heavy it is. An Alpine amplifier with one channel was defective. Replaced four with this Infinity Kappa, sound quality doubled with this amp. Definitely recommend.

Pros
  • Low distortion
Cons
  • I'll be silent

Big sound in a small package!

I bought this Kappa amp because every time I've seen Dyno test these amps they put out more power than advertised. I've done quite a bit of research on this. When it arrived it was smaller than I expected and I was a little concerned. I use a Kappa 6.5 3way with a passive motor in the front of the car. For the rear doors I chose Kappa Coiaxl. This Amo simply delivers pure power. I went for Dasita Android head unit and they claimed they are too weak but I will never know about it. Thus, all 8…

Pros
  • Includes: 1 amplifier, 4 differential speaker level adapters, 2 spare fuses, 4 Phillips screws, 1 EARL clamp, 3 self-tapping screws, 1 instruction manual
Cons
  • There are other interesting options.
