Question about Kenwood KAC-X650D Car Audio Amplifier
My amplifier has worked without any problems and was installed by a professional installer. Wiring is perfect i.e. power supply etc. The amp went into protection mode. I removed and took to local auto stereo shop (very high end known for service and custom install etc.) They sent the amp in to Kenwood for repair. It has been returned and NOT repaired with an explanation: To much "corrosion". I removed the back panel and it there appears to be no corrosion what so ever. Any suggestions on other options to have it repaired? Or what to look for? Any way to "reset" the amp?

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.

Does it go into standby when it's in another mode like : Cd or Video 1 or tape?
When you state that you checked the power amp IC's , how so did you do this?
Thanks n' let me know.

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.

it sounds to me like its burnt.but with some amps the screws that hold it in place have to be screwed into the car chassisfor grounding. be careful not to srewe into hidden wires.

SOURCE: To bridge a Kenwood KAC-9102D
The Kenwood KAC-9102D is a mono amp. There is no bridging. Having two sets of terminals is just a more convenient way of connecting two subwoofers. The amp is stable down to 2 ohms impedance, so it is safe to run 2 4 ohm loads in parallel.
Hope this helps.
