on mine...sub rumbles the whole house when i do the speaker test...but no other sound comes from it. same problem. see if it shows up in speaker test.
SOURCE: Kenwood KAC-8103D 1000 watt issues
Apparently it won't let me log in. Anyhow... I'm pushing voltage. The light is flashing, not flickering. How can I replace the transistors?
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.
Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/mark_b53a7494531bf96d
SOURCE: i just received this kenwood 100 watt powered sub
check the transformer has ac around 50 vac. then check the dc power supply at +_ 45 vdc if all that is ok,check the output ic has +- 45 vdc at 2 of the pins,if it does,the output ic is probably no good
SOURCE: amp light is on but no power to my subs!
Hi There.
When you say the 40 Amp fuse blew. Was it your mains battery fuse or was it the fuse on the amplifier? If it was the fuse on the amplifier then you may have hurt the amplifier. The Kenwood KAC-8101D is a 1000 Watt monoblock amplifier. Therefore if you say that 1 of your woofers is not playing, then it is almost certainly blown if you are sure it is connected correctly. Try disconnecting it and only running the woofer that tries to play. If this woofer is still working correctly, you will notice a drastic drop if the sound of your bass. The reason for this is because you have changed the impedance load on your amplifier due to the fact that the other woofer is not working. Have your working woofer checked and replace the faulty woofer then you should be banging again.
Hope this helps!!
