HAVE A KENWOOD AMP MODEL KAC-9102D . iT KEEPS SHUTTING OFF WHEN i TURN THE RADIO LOUD. ANY SUGGESTIONS

speed hacker

do you have the rem (remote turn on) connected to the remote turn on lead from your head unit? what make and model is your head unit>?

could be you don't have enough voltage going into the amp or it could be the pre amp in between. if your voltage is below 11 volts then you need more voltage. you should have at least 12 to 14.4 volts.or you might have a small short in your amp.

Hello laurogleal,

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.

i had this same prob. & i run 2 amps as well, cameto find out i had a neg. & positive touching , so check all ur wiring for tht amp..

You will probably need to use a Line Output Converter (LOC). They're available at virtually any shop that sells car audio.

Many times, the outputs of the OEM amplifier will have significant DC voltage on them. This could damage the input circuits on the kenwood amplifier.

Let me know if you have any other questions.

My recommendation is to get a line level converter. Go to a car audio shop or even best buy and specifically ask for a line level converter. It will have speaker wires in and RCAs out. Connect the speaker wires to the sub woofer speaker wires and then you will have the RCAs to run to your amp. I hope this helped.

You need to confirm that the B+ voltage isn't dropping at the amp.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) 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.

put a the amp the max charge permitted, and y you have a preamp you can makeit work.

Try to turn down the volume??? LOL No really most likly the voice coil is overheating on the speaker, or the unit is over heating. Try to add a fan on top of the unit as I found this on high powered units, that they are being push hard and getting hot. Is the amp really hot when it does this? If it is then its a normal thing as not enough venilation. if its not hot then theres a problem in the amp and should be bench checked by a pro with load resistors and a tone generatoe as well as a scope to check if theres a clipping problem in the output stage.
