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.

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.

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.

SOURCE: amp goes dirctly into protect
ok well it could be two thing wrong your amp dont have a good ground or your amp is a smar amp and your subs must have to be hooked up so the power from the amp cn go to the subs so the amp can see that you do have subs hooked up to take it out of protect o and look at your fuses to to smal or to big will send it to protect to

from what i have read about your amp, it is already a mono amp, and rated for 2 ohm's, so all you have to do is wire the subs in parallel (both positives together to positive and both negatives together to negative) or series/parallel if you have dual voice coils (both positive and both negative paired on each sub, then positive from amp to positive on one sub; negative on that sub to positive on next sub; then negative on sub to negative on amp) Note though, with two dual voice coil subs, you can have a 1 ohm load with the first set up, which can damage your amp. Let me know if this helps :)
