OK soo the other day i was driving down the road and my sub woofer blew soo thinking that was the problem i went and bought a new subwoofer now thats installed still no sound.... The power to the amp is on as indicated to the red light powered on but still no sound all connections are good and double checked everything i have run out of things to look for plzz hlp
Just purchased a brand new Kicker ZX650.4 amp. It was installed and was working fine for four days in a row suddenly no bass and no sound. check the amp wiring and fuse. every thing is in good working condition. So I turned on, off the stereo suddenly the amp has power again but then as soon as the bass drops the amp dies. but what was strange the second time. The amp power led light slowly dimmed then no power. what was also strange my cap was fully funcitonal so was the stereo. help
Check the main amp fuse under the hood, even if it looks good just change it. Often times that light on the amp can come on just from the power amp tunon wire. Try a friends subwoofer box just to make sure the connectors on your box are good, and if that doesn't work then give me some more details....year/make/model of car, what kind of sub, what types of things do you see on the side of the amp....is there a green light as well as a red light?

Tip: The max point reward for answering a question is 15.
**First thing is verifying that the powerlight is lite up, this shows that it is receiving power and is grounded properly.
**Next thing you need to ensure is that the remote wire is connected properly on both the head unit and the amp.
**Third Make sure the RCA wires are all connected properly, try jiggling them around on the amps end to make sure there not just shorting out.
**Check all fuses related to the amp to make sure all the channels are working properly. (Applys to amps with multiple channels and fuses)
If all these things are fine, then the sub could very well be blown. Did you have it up loud before it stopped working ? You said it was working fine then just went all quiet, did the head unit power down as well ?
Post back with any further info or questions so that I can assist you further.
You did not say whether or not you checked the wiring going to your subs. Many times, a shorted or grounded speaker wire will cause an amp to fail. And if the amp powers up OK with the subs disconnected, I'd suspect one or more of the wires.
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.
there are fast checkings for you:
Quick Connect Card
is the system working fine exept the sub?
my guess: the headphone jack works fine then the speakears are too
if soo then the sub amp is bad
or some connection is torn
try opening the sub and see if everything is hooked right
and if soo then the amp is the problem
every electronics shop can fix this
