Unhook the Speaker leads from the amp and check for resistance between the two on the amp... it should be 0... now reattach the speaker wires to the amp and check the resistance...depending on the load at which the amp is stable it should be more than 1 ohm at the least...2 ohms on most amps. If all that checks out, check your pre amp inputs. Maybe something came loose behind the deck.

I have the kvt 617 I have great audio when listening to radio nut anythig else I only have subs it started doing it when i first got it and then it quit and know it is doing it again any idea?

High end kenwoods have a setting, where you can turn off the internal amp in the head unit, if the sub is the only thing that has an external amp hooked to it, and it is playing, that may be your problem. Also, if one of the speakers hooked directly to the Kenwood has a short, bad voice coil, or contacts touching metal, that can cause the amp in the Kenwood to go into protect, and you will loose sound to all the speakers.

Kenwood KAC 7202 amp not powering on

First you should test to be sure the amps main power feed is supplying 12+ volts to the amp. and that the other connections (head unit remote lead - input & output signal leads) are properly secured, if all is well then there maybe an internal issue with the amp.

It is not recommended to affix an amp directly to a speaker/kicker box, hence the vibration that may cause wire connections and/or internal electronic components to become loose or faulty.

As far as "should i take the amp apart and look at its guts"

NO, sorry but given the way you phrased your question I can assume that your electronic troubleshooting knowledge is not up to par, and that task would be a waste of your time.

Good luck

My kenwood amp wont turn on

What kind of "Clips" did you put on? They may be causing too much resistance and preventing the amp from getting the current it needs. Double-check with a voltmeter that you are getting at least 12 volts at the amp power connections and make sure your ground lead is as short as possible and connected to solid metal of the vehicle's chassis.

Since Kenwood makes a lot of amps, I can't be specific. Check to see if speaker (A/B) is switched on. Make sure "mute" switch is off. If useing tuner, make sure to hook up AM/FM ant.

Amp Problems

You are probably presenting too low an impedance load to the amplifier. In bridged mode the amp must be connected to a minimum 4-ohm load. If your subwoofer is a dual voice coil type with 4-ohm voice coils, you cannot wire the voice coils in parallel and connect it to the bridged amplifier. If you have a sub with dual 2-ohm voice coils, you can wire the voice coils in series and connect it to the amplifier in bridged mode. To connect voice coils in series: Connect a wire from the negative terminal of one coil to the positive terminal on the other coil. Connect the unused positive and negative terminals to the amplifier's output.

My Kenwood KAC 9152D 1800W AMP acting funny

Sounds like you got the wrong speaker load by either parralleling some speakers or else you bridged the outputs in such a way to create the wrong speaker load or maybe all of the above. In short, it sounds like you have blown at least one of your output channels and its time for a trip to the repair shop. I suggest you disable your amp at once so that it doesn't do any more damage to itself.
