The first thing you must do is to confirm that you have voltage at the amp. Just because the fuses look good, that doesn't mean you're getting power to the amp.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

SOURCE: Kenwood KAC-7202 wont turn on

I have found the problem to my Kenwood KAC-7202. The amps fan was the only thing that would come on thats it. So I started checkin zener diodes cause all transistors checked out fine. So I remember readinf about a guy that had same problem and took it to a shop and they said it was some diodes. Well, thats what I was thinkin or the transformer. It turned out that 1 zener diode was no good, diode D9 1ss133. I took a zener out of an old vcr I use for parts and put it in and the fan came on as usual then the red light. Then I hooked my mp3 player to the rca input and hooked up some speakers and it works great. Hope this helps you other guys with the same problem. Check your zener diodes with a digital volt meter, if you get any measurement other than the reverse impedance which will read between 600 and 1200 ohms some lower or higher and then reverse the leads on your meter and if you get any reading it's no good and the reading will be 0-50 cause mine read 047 ohms.

Hello mogly20,

The amp probably won't know if it's you or the homeless guy, so try smashing a glass bottle on it like he did. If that doesn't work, I'd recommend you locate another homeless guy and buy another amp.

Hope this helps.

My amp blew the 20 amp fuses. Replaced and they blew as soon as the radio kicked in. Took the back off to look for any burnt connections or blown open/expanded capacitors or resistors. It smells like...


Remove all the wires from the amp including the remote turn on wire. Once you do that, after about 30 seconds the amp will reset. Hook the power up first, then the ground then the remote. Turn the unit on and check for power WITHOUT the speakers hooked up. If you get no power by now it's a good chance that the amp is cooked. If you do get power, try hoking up your speakers first on one channel then the other channel and then bridged. If it cuts out or off when you touch the speaker wires to one channel or the other, then that channel is no good. Hope this helps.

I have a kenwood kac-728s and two coustic 10in. subwoofers hooked to it and every time i start my car and the radio powers on the two 20 watt fuses on the amp blows.any ideas?


That is pretty much saying that the amp's power supply is shorted or at least has a low resistance path to ground which is causing the fuses on the amp to blow. The amp has protection circuitry to prevent damage to the output stage so that is not what is causing this. Is the amp new?
