20 Most Recent Kenwood KAC-9103D Car Audio Amplifier - Page 8 Questions & Answers

Hi Trey, i understand that you not a technician, what i do advise is to first get your head unit bench-tested, have all the output channels and currents checked thouroughly. If that doesnt sort the problem then try a different head unit as a process of isolation. If the problem still persists with a new head unit, then the problem is definitely with the points of connection from the head unit, OR you may have a weak battery. The amplifier will not bring on a miswire fault in the head unit. Cheers.

NO KENWOOD amp model stated at all (vast there are) wild guess speaker or wires to them shorted or open.

RTM . typed the number wrong , kenwood KGC4300 equalizer WANT DIN PLUG PINPUT. on IS THIS A CAR RADIO AND YOU LEFT OFF THE KGC4300 THAT IT/? 35 years old today, that? 1985 made !

the amplifier of the tape is dead or it need service

There is a setting that turns off and on the subwoofer

I think there is a switch to go from output 3+4 to subwoofer

The ground wire check.

Make sure ground and power to the AMP are perfect (clean and tight). Afterwards unplug all the speaker wires and/or RCA speaker connections. Does the light still flash and power down after it is reset? If so, the AMP may be damaged. If not, then one of your speaker wires are shorted. Plug one speaker in at a time. One of them should cause a negative reaction.

VIDEO CARD READER OF UNIT IS BAD YOU HAVE TO FIND A TECH SUPPORT WITH KENWOOD TO FIX

check all the wiring at te back the push and hold reset button for ten second and try power again

push and hold rest bull with a small pin and the unplug unit for ten second then try power up again

Typically those car radios have an embedded (on circuit board) chip which is a flash EEPROM type memory. And this chip stores data which was programmed even if power is removed to the system. It also cannot easily be erased. They engineer this on purpose because any workaround to there anti theft system would defeat the purpose of having it so. Um I'm 99% certain without that code you basically have a brick which won't power on. And nothing you can do can change that. Perhaps and engineer or something could replace the chip or I have heard of ways to wire in and basically short certain leads causing the chip to delete it's memory without actually destroying it but that is engineer level stuff. Buyer beware I would definitely get a refund on that. A quick Google search of Kenwood 6140 password comes up with this to confirm what I already know about this technology. Also with 4 digits there are 10000 different combinations. https://www.manualslib.com/manual/705744/Kenwood-Dnx6140.html?page=74
