Question about Kenwood KAC-859 Car Audio Amplifier
I Have one of this amplifiers, the problem is, i'm listening to music, and then suddenly one channel starts to crisp and making noises like static, then the channel goes off... If i increase the volume enough(at stereo level 20 out of 30) the channel gets on again and sounds normally, till sometime the channel goes off again. If when the channel goes off, i increase the volume a little bit but not enough, the channel sounds like the music but with very much static and irregular noise. It wont stop... what could it be?

SOURCE: power of amplifier
If the KAC-7252 is to be bridged, the operation mode switch on the top of the amp is set to mono. When switched to Mono, the signal from the left channel input only is used. Bridging creates 4 times as much power so the KAC-7252 delivers 170 Watts per channel so that 340 watts total so that value 340 is multiplied by 4 and that gives you 1360 watts of power. so it will drive them.

I had a similar problem with a KAC-X812D Kenwood amplifier.
My problem turned out to be that the RCA inputs were so sensitive, they picked up interference from my head unit through the RCAs.
I replaced the head unit with a newer model, and had no problems after.
This may not be your case, but hope it helps.

Its not pulsing, its called clipping. The sound is being clipped due the amp being pushed past is power capacity and distorting the signal. This will damage your speakers very quickly. No amp should be turned more then 3/4 up. If its not loud enough you need to purchase a larger amp or be comfortable with the wattage it produces at 3/4 volume. You may also have speaker wires touching/crossed causing th issue.
